Introduction:- Fiber cement is used for manufacturing of wall

panels, partitions and cover plates (sheets), which are used extensively inmodern construction for many years. However, the unit weight of cement boards

is still high, more than 2000 gf!m".#n order to adapt the varieties of thefunctions and the space for high$rise structure, the partitions to separatebuilding space demand to be lightweight, easy to construct fast and assembled simple. cement board, calcium

silicate board and gypsum board are common used as the materials of building partition. Among them, moisture

content for calcium silicate board and gypsum board gets up to 80% and 75%, respectively, in humid climatic

conditions. High humidity made the partition deform and warp easily in use. ne of the methods to improve the

deformation of building partition affected by humidity is to add some fibers into the partition board.   %he useless agricultural products lie rice$huss,sugar cane$dregs and coconut shellare always thrown away as thewaste without any considerations in%aiwan.#n fact, theseagricultural wastes containing some natural &bers are valuable and can utili'e to improvemechanical properties of the materials.%his paper selects four natural &bers collected frombamboo, coconut shell, rice$huss and sugar canedregs,respectively, to produce natural&ber cement board considered as the building partition. e discuss material properties of

natural &ber cement board includingwater absorption, bul density, length change inducedby absorption of water, impact endurance,&reproof capability and heat$resistant capability.

 %heexperimental results can be used as a reference inbuilding industry.

 APPLICATION AREA OF FIBER CEMENT BOARDS LATONIT

! "entilated facades give the building a modern loo#, e$tend service life, and also serve as a goodway of insulation

! &nterior finish of walls and ceilings of rooms in which there is high humidity stadiums' interiors,

swimming pools, water par#s, bathrooms, lavatories and utility rooms

! &nternal wall decoration of premises with high fire safety re(uirements )walls around the furnace insaunas and baths, etc.*

! +acing the screens of balconies and loggias! &nterior walls

! underlayment under metal roofing tile, metal profiles, roll roofing, ceramic tile

! andwich - panels

! +acing ventilated and elevator shafts! ound-absorbing barrier fence lines

! oof coverings, awnings, cornices! /reate multi-layer material

! /omposite panels.

ADVANTAGES OF FIBER-CEMENT BOARDS LATONIT

! on-flammable, non-flammable and do not spread the fire, have good insulation properties,

resistance to microorganisms and chemicals! Allow to re-create any geometry of ventilated facades, remove the bumps without pre-treatment ofthe bearing wall

! 1he possibility of year-round installation, regardless of the weather conditions, thereby reducing thetime of delivery of ob2ects in operation

! esists 3" and magnetic radiation. +rost resistance is 4- times higher than in the performance of

 bric#, which allows to withstand low temperatures

! 1he use of panels for the interior decoration of buildings and structures reduces the production timeof finishing wor#

! A high level of (uality than#s to the most modern e(uipment installed at the plant! 6o not rot and spread mold, have a significant resistance to weather and climate variability

*fter autoclaving do not have calciferous blooms, ac+uire greater strength andresistance to impact.
