Foreword of LUCEMDear Sir or Madam,

Dear architect,

Dear building owner,

We have been delighted with the interest shown in our product since its recent launch. In line with this, and at the request of archi-tects, designers and other professionals in the sector, we are pleased to welcome you to our First Edition brochure for the Speci-fication and Application of our Light Transmitting Concrete.

Our planning details seek to demonstrate how LUCEM can be opti-mised in practical use. However, due to the infancy of the product, the extensive applications of LUCEM light transmitting concrete are still being developed and this should be regarded only as an indica-tion of its potential.

Having carefully worked in the publication of these planning details and tried to best describe the applications of LUCEM light transmit-ting concrete. We recognise that many of the sections in this docu-ment may be worth of improvement. Critical feedback will be much appreciated and contributors will be mentioned upon request in the foreword of our revised brochure, scheduled for publication at the end of 2011.

The second edition will contain an additional chapter with refer-ences arising from BAU 2011.

Thank you for your cooperation.

Stolberg/Rheinland, March 2011

Cordially,

Your LUCEM-Team

Company

LUCEM Lichtbeton GmbH

LUCEM Lichtbeton GmbH, located in Stolberg near Aachen, spe-cialises in the fabrication of light transmitting concrete products which can be used widely in architecture (as facades) and interior design in a sustainable and aesthetically pleasing way.

LUCEM Lichtbeton GmbH currently has a workforce of 15 employ-ees based at the production plant in Germany where exclusive pro-duction techniques are regularly being updated to meet market de-mands. The ongoing product development makes LUCEM a reliable partner and via national and international business partnerships, the expansion within the building industry is gaining pace.

An innovative production process created the foundation of the LUCEM technology which Andreas Roye and Marijan Barlé developed between 2007 and 2009.

Established in April 2007 as robatex (Roye Barlé Textiles), the fabrication of light transmitting concrete was developed systemati-cally with the creation of a production line.

However, since 2007, all the robatex products were distributed worldwide as the trademark LUCEM. The renaming of the company name from robatex to LUCEM Lichtbeton GmbH took place in Octo-ber 2010 with the aim of achieving a uniform outer appearance.

Company

LUCEM Lichtbeton GmbHLUCEM products are specialised, innovative and of the highest quality „made in Germany“ for the worldwide market. They have been praised by architects, interior designers, investors and private clients whose support led LUCEM to exhibiting in the German pavilion on the worldwide fair Expo 2010 in Shanghai.

The LUCEM trademark combines the highest quality with a timeless aesthetic: high-performance concretes and translucent fibres that are durable and hardwearing resistant to weather, UV-light, impact and non-flammable.

The translucent aesthetic combined with the mass density and solid form material catches the eye.

Polished, glossy or sheen/matt surfaces are outstanding character-istics of LUCEM. The surfaces can be designed individually with the addition of colour pigments or differing arrangements of fibres.

LUCEM produces panels that are available in untrimmed sizes, al-lowing these to be randomly arranged similar to natural stone.

LUCEM offers support to designers, architects and those involved in any project where the LUCEM product is being considered. LUCEM assists in selecting the best mounting and lighting system to suit the individual project and provides advice upon its application and di-versity in use.

A comprehensive support service through planning, processing, manufacturing and construction is available from within the LUCEM network of contacts.

Light transmitting concrete

Optical fibres

Concrete

Light transmitting concrete

The point: a mathematical element without dimension. However, if the origin is a beam of light totally internally reflected through an optical fiber encapsulated in concrete then in plurality a notable transparency results and a new dimension of this fundamental material arises: LUCEM Lichtbeton.

Water, sand and cement form concrete – ultra-fine optical fibers break through the concrete mass punctually whilst mechanical and haptical characteristics remain untouched.

The transmitting optical fibers get parallelised and then – layer by layer – embedded in the concrete. Thus, a large formatted con-crete is realised as the basis for cutting the panels.

The surfaces of these panels are polished to reveal the fine smoothness which enables LUCEM to become a creative work of art.

Lighting wire - theoretical

Functional principle

Diffuse natural light and sun light provide the full spectrum of co-lors shining through the LUCEM panels. Sunlight is the most inexpensive light source. If LUCEM is mounted free standig or in front of a window, no arti-ficial light source is needed.It should be noted that brightly lit rooms may affect the contrasting effects of LUCEM.

Differing methods of mounting and artificial light sources build up steady colours or fascinating effects and offer unique and exqui-site aesthetic effects for the designer.

Mounted as a wall or floor panel, LUCEM light transmitting con-crete must be lit with an artificial source to guarantee an illumina-tion of the reverse face of the panel.

Indirect light creates a special effect for interior space, especially when the LUCEM panels are the only source of light. Due to the special optical effects of the fibres, the wall panel varies in colours from every angle of the room.

Long-distance effect

Close-up view

LUCEM LineDue to a fine-meshed structure consisting of light transmitting fi-bers, the impression of a lightweight structure which in conjunc-tion with illumination elegantly reveals silouted objetcs.

During processing of LUCEM LINE, a highly-fluid cement with specific granular size joins fine-meshed fibres. Due to this proces-sing, a consistent surface arises, with thousands of translucent fibres breaking through.

Light and shadow are shining through LUCEM LINE perfectly.The human eye is able to complete the missing points automati-cally so that it seems as if one could see the whole hand.

LUCEM LINE often is installed as a decorative wall panel due to his liveliness in fibres, appearing almost like a work of art.

LUCEM Starlight

If fibres with different diameters are used in irregular distances in between each, the single light points appear brighter – forming a punctual transparency like the impression of a starlit night. The concrete material disappears into the background.

If fibres with bigger diameters are used, the single light spots ap-pear brighter. A local brilliancy arises the impression of a very bright surface although less than 1 % of the surface is consisting of light spots.

LUCEM Label

If required, the light transmitting fibres can be arranged in logos, names or icons – a guarantee for an individual and distinctive ap-pearance.

Unique prints can be produced, which can be delivered as single-piece production, as small or big series. Entrance or guidance signs but also functional facades can be designed.

Color variations / Textures

LUCEM light transmitting concrete is a mixture of fine concrete and optical fibres. These optical fibres are responsible for the lighted surface - the sheen. Concrete is normally a mixture of sand, cement and aggregate and the larger aggregates in the texture of LUCEM light transmitting concrete greatly influence the final appearance. The aggregate granule is the only visual fea-ture if light is not shining through the concrete. Combined with translucent fibres, the structure of the concrete is responsible for the outer appearance of LUCEM light transmitting concrete. Concrete consists of a mixture of cement, pigments and sands. The production of LUCEM light transmitting concrete is always based on white cement and therefore can be delivered also in white colour. The colours grey and anthracite are coloured with pigments of ferric iron oxides. LUCEMʼs light transmitting con-crete is available in three colours which have been tested for long term durability. In addition to the pigmented white cement, the aggregates are mixed with 50 % sand.

LUCEM currently offers the following concrete mixtures:

Ulmer White, 3 mm grain

Grey calcilith, 3 mm grain

Anthracite calcilith, 3 mm grain

It should be noted that LUCEM light transmitting concrete is tra-ditional concrete and therefore minor variations and irregularities are to be expected. Air voids also occur in light transmitting con-crete and may have a size of 2 mm diameter on the surface.

The design of LUCEM LINE represents a horizontal layering whilst LUCEM STARLIGHT has got a terrazzo-like appearance.

LUCEM light panels

UseMounted as a wall or floor panel, LUCEM light transmitting con-crete needs an artificial light source to guarantee complete illu-mination of the reverse of the panel.

ProductLUCEM light panels are small plates that are lit laterally with high efficient energy-saving LEDs. The light panels are 4-10 mm thick and available in different colours. The use of RGB-LEDs allows static or intermittent colour changes. Single elements can be interconnected and the system dimmed in brightness. In contrast to other deeper systems, the lighting occurs laterally - depending on the size of the panel and the desired luminosity - LEDs can be installed on one, two or on every side. LUCEM light panels are marked with an individual raster or laminated with prism film to guarantee a homogenous spread of light.

SafetyThe use of low voltage (12 V) increases safety and makes addi-tional protection classes up to IP67 possible.

Efficiency and sustainabilityLEDs are said to be very efficient concerning effects and light yield. The LED life span counts 80.000 hours and reduces the regular exchange of light sources.

CuttingThe standard size is 1.2m x 0.60 m with cuts and recesses in various profiles produced precisely.

Classiness, high-grade furnishing and flawless services for public health.

The new building of an oral surgery clinig presents a large-sized LUCEM wall used as a room divider.

A brightly illuminated waiting area induces an interesting shadow play on the part of the offices.

Throughout the massive wall the amount of waiting patients can be counted.

Light shining through at the hallway

The room concept in the whole clinic, being divided into waiting area, consultation area and medical treatment area, was designed as massive wall construction consisting out of LUCEM LICHTBE-TON and being translucent and brightly lighted in the outer ap-pearance.

A tongue-and-groove joint system with vertical steel sections was developed for mounting.

3 panels each got built up as room-high segments. In all, 10 parts consisting of 3 panels each were mounted as a wall construction. The passage in between each 3-panel-consruction was mounted with a vertical-standing steel flat bar (dimension 70 mm * 10 mm, room-high with fixture at the concrete ceiling and at the concrete floor) with exactly positioned pins at the edgeways. These pins were chosen with an adequate diameter to mesh in a 7 mm slot included in LUCEM panels.

Light transmitting concrete is a special highlight to design special objects.

The bar of a hotel at Spitzingsee on the one hand seems to float due to big-sized light transmitting elements, appearing as stable concrete on the other hand.

The processing like natural stone allows an easy application of extra elements, e.g. a foot rest.

The cold light contrasts with the warm colors of the interior design and shows if the bar is opened.

Roomconcept, color design, materiality and art: those were the main subjects, Sassan Philip Haschemi & Associates worked on, picking LUCEM LINE panels as a special highlight: LUCEM light transmitting concrete panels for the entrance hall and the excecu-tive suite. The LUCEM LINE panels have been designed as floor to ceiling wall claddings utilising free space behind the panels for light supply. The special color of the light source was made con-sistent with the colors of the interior design by using a LED source with warm-white light.

“LUCEM gave us the opportunity to provide creative accents, which harmonise with the entire interior design and the art-work concept”, says Sassan Philipp Haschemi.

LUCEM panels have been installed nearly without gaps. Thus, theinner structure of the panels seems to glow from inside itself. Due to the ease of processing, all operating elements and displays have been integrated completely planar to the surface.

All in all, 9 lightpanels in special frameworks with the size of 1,2 x 3,5 m were installed to accompany the elevators across three superposed floors.

Surface : approx. 1,0m²Completion: December 2010

Planning and implementation: LUCEM GmbH.

A private building owner was looking for an eyecatching design for the main entrance area of his large-scaled residential house.

With the aim of integrating this feature as harmoniously as possible, a LUCEM LINE surface of 0.50 x 2 m was embedded into the wall.

To highlight the product characteristics, the panels were mounted with invisible screws without affecting the troweled surface of the wall.

The special flat light system used, allowed an easy installation of the light transmitting concrete panels.

Thanks to the energy efficient light system used, only a low voltage power supply line and an AC adaptor were required for the installa-tion, enabling the installation to be completed in only four hours.

Unlit during the daytime, the surface appears as a high-spec con-crete material with a sanded terrazzo finish; in the evening and dur-ing dawn the appearance of this surface changes completely into an area with numerous light sources in the room.

Idea

Implementation

The relief of the wall strengthened the shadow and light effects and impressively demonstrates how robust and stable light emitting LU-CEM panels can be effectively used without visible wiring.

To achieve this, LUCEM developed a design consisting of standard-sized LUCEM light transmitting concrete panels.

The LUCEM booth at the fair BAU 2011 was built to present LUCEM light transmitting concrete demonstrating its versatility but maintain-ing a uniformity of design.

Details

On a surface of 5 x 7 m and a height of up to 5 m, the products were installed in a imposing architectural context. On the floor, an illuminated and loadbearing surface made in different formats caught the visitorʼs interest. The textural walls were mounted with anchors on a lightweight alu-minium framework.

Mounting systems

MountingBoth, the mounting of the LUCEM panels as well as the technical characteristics of stability and tolerance are similar to those of natu-ral stone.

Although any alterations on the LUCEM panels such cutting and mounting holes are recommended to be done during casting, they can be done on site by wet saw cutting or by dry cutting provided that good ventilation is available.

In general terms, the product specification in LUCEM is similar to that for granite products.

During the installation of LUCEM and due to its translucent nature, the existing sources of light should always be taken into account when mounted free standing as all mechanical elements are visible through LUCEM.

When installed free standing, we strongly advise that the number of elements behind the panel are kept to a minimum to avoid un-wanted shadows and to allow the characteristic sheen effect of the product to be retained.

To guarantee a translucent surface on free standing constructions we recommend the use of a metal support structure. Pre-cast fa-cade anchors can be used. Floor panels can be mounted flat upon different substructures. Due to the nature of the LUCEM light trans-mitting concrete, it is of the utmost importance to always individually adapt the lighting system to suit the method of mounting.

LUCEM is most commonly supplied with a flat LED lighting system to minimise the installation depth.

During mounting, LUCEM should only be handled with dry and clean gloves. Remnants of oil or grease will be very difficult to re-move.

Although LUCEM light transmitting concrete can be installed in many different ways, it is important to consider the lighting system that will accompany the panel. Please find examples of three ways of mounting - screwing, under-cut anchors, Halfen fixing system - in the following drawings:

Maintenance instructionsCleaning / Hydrophobic effectNearly like every product, LUCEM envinces signs of usage. Please stick to the following maintenance instructions to guarantee that LUCEM will be as shiny as on the day of mounting.

Factory-made protectionLUCEMpanels are delivered with a water resistant impregnation (hydrophobic effect) so that the surfaces are protected against slight soilings.Although, concrete is a water absorbent material. Please always remove liquids with colour pigments of LUCEM panels immediately. For cleaning, a sponge or a cloth should be used.

Our light transmitting panels in addition are protected with a foil. The surfaces of the light transmitting concrete are protected against soilings during processing of the elements. After processing and mounting, the protecting foil can be removed by lifting up its edges carefully with a knife.

Refreshing of hydrophobic effectThe hydrophobic effect may decrease depending on usage and in-tensity of cleaning. Therefore, a refreshing of the hydrophobic effect is suggested and is always possible.

We suggest to use standard hydrophobic mediums for concrete. Before refreshing the hydrophobic effect, please pay attention to the safety instructions of the fabricator.

CleaningWe suggest to use pH-neutral and non-abrasive detergents or natu-ral stone detergents for cleaning. Please never use acids, e.g. vine-gar, benzine, turpentine, acetone, antiseptics containing phosphoric acid or alkalinous products for cleaning because they may attack concrete surfaces.
