Highly Efficient Production of Aerogel Insulation Materials and Their Integrated Composites and Systems (ICECLAY)

ICECLAY is to generate new, alternative, lightweight and cost-effective nanostructured aerogel solutions, specially designed for energy efficiency goals and able to provide superior thermal insulation for new build, building retrofit and advanced HVAC systems. While common aerogels are generally unaffordable expensive and based on hazardous production processes, the ICECLAY solution will be made by a versatile and environmentally-benign novel process, using only harmless and inexpensive raw materials for the production of novel materials and composites.

Value Added Construction Materials from Wastes

The aim of this research programme is to find a solution or uses for wastes as materials production and construction produce over 150 million tonnes per annum or 35% of UK total waste, and thus so will the problem with wastes. The principle objective is to develop and provide [industry with] a series of viable, environmentally, user friendly and low cost innovative construction products made from wastes. Research projects/activities in the programme include:

nano-Cellulose and High Strength natural fibre Composites for Structural Applications

The aim of this research programme is to develop strong civil engineering products from natural resources, to be used in building construction and potentially the automotive and aerospace industries. The originalities are in the novel process of natural raw materials and application of innovatively processed natural resources (from nano to macro). The developed materials are to be tested in combination with nano-modified thermo-setting matrices through a number of forming processes such as compression moulding. Some of the projects in the research programme include:

Project: Nano Cellulose and Applications (TSB Co-funded)

Project: High Strength Straw Composites and their Use in Construction (DEFRA Co-funded)

Project: Efficient Production of High Strength Natural Fibres and their Engineering Products (TSB Co-funded)

Project: Waste Management (BRE Co-funded)

Project: Research into Wood Wastes and Used Tyres for Innovative Construction Products (EU Co-funded)

Project: Research into Using Recycled Waste Paper Residues in Construction Products (WRAP)

Advanced Cement Based Materials

The aim of this programme is to develop cement-based and nanotechnology-enhanced materials and new methodologies for modelling and experimental processes. The research programme also investigates the performance of the developed materials and their building components, such as roof tiles and sidings. Some of the research projects in this programme include:

Innovative Timber glullam and Beam

Timber Glullam and I-beam are major wood-based composites that are used increasingly for structural or semi structural applications in construction. Products continue to take a larger share of the engineering component market from timber, steel and other products. The structure and orientation of constituents to the stresses applied in construction are crucial. This research programme includes research projects on modelling and manufacturing and design technologies to develop the optimum structure with the dedicated performance, and on the reuse of reclaimed timber beams in the construction industry.

Project: Converting Low Value Raw Materials into High Value-added Construction Products (Nigeria)

Project: Re-engineered Timber Products and their Construction (Industry)Project: Re-Use of Reclaimed Timber Beams

Project: Shrinkage Cracking of Hardening Concrete (EPSRC)

Project: Nanotechnology Enhanced Extruded Cement Based Sandwich Material for Building Applications (EU Co-funded)

Modelling Structure failure at Elevated Temperatures

The aims of the research programme are to 1) develop a mesh-independent layered procedure to model localised crack initiation and growth in plain concrete slabs subjected to out-of-plane loading and temperature distribution, and to integrate the layered plain concrete slab element with existing reinforcing steel bar and bond-link elements for modelling of reinforced concrete floor slabs in fire; 2) to perform detailed studies on the influence of support conditions, bond characteristics, and reinforcement details; 3) to investigate in detail the localized integrity failure of the interface zones between highly deflected composite floors and reinforced concrete core walls; and 4) to postulate an initial set of design recommendations for composite buildings for a performance-based structural fire engineering philosophy.

Project: Modelling Localized Fracture in Composite Floors (EPSRC)

high-resolution stratigraphy of deformed soils, detailed characterisation of soils and radiometric dating, including 210Pb analyses. Recently published work on the Düzce Fault in western Turkey (surface rupturing earthquake: Mw7.2, November 1999) was part of the EU-funded RELIEF project).

optimum Method of Procurement for a given Construction Project (Libya)

The aim of the research is to develop a new procurement selection mode/framework and some recommend practice that will aid clients’ decision-making on the optimum procurement method to use for any given project. Achievement of this aim will entail pursuing the objectives of reviewing critically the different types of procurement methods currently in use in construction projects; demonstrating the applications of the various procurement methods and their suitability of use in practice; reviewing critically project performance criteria and factors affecting success of projects in the light of procurement methods characteristics; reviewing and developing an appropriate model for the selection of optimum procurement method for any given project; testing and validating the developed model to ensure its applicability in practice.

fire Characterisation of Innovative Structural Building Products (BrE Co-funded)

The aim of the project is to develop effective building systems made from natural materials and wastes, in particular, the innovative products from biodegradable municipal waste (BMW) (from bin liners) through assessing high temperature performance characteristics of the materials and optimising performance levels to meet a certain assembly of components or end uses of products.

Earthquake impacts and ground deformation

Earthquakes present a major hazard to society and an understanding of their likely re-occurrence and their impact on ground conditions is essential. Recent research at Brunel University has been focussed upon the recognition of past earthquakes from soil and sediment sequences. To date work has been included sites in Turkey, Italy and Scotland, with a variety of partners including the Istituto Nazionale di Geofisica e Vulcanologia in Rome. The approach is multi-disciplinary, employing a variety of field and laboratory techniques including
