LIGHT WEIGHT BUILDING MATERIALS

LIGHT WEIGHT BUILDING MATERIALS

Abstract

            The building construction work doing the material has taken in dead load. The dead load is high the structural design to resist the load to section is heavier design so the building cost also an increase. To use lightweight material use in building the section design is economical so building cost also reduces it. This method is now very essence to our country. Here in this paper we are going to discuss the various features, application, and advantages and test result of the lightweight materials.

AAC BLOCK/AUTOCLAVED AERATED CONCRETE BLOCK    

Introduction

    Areated concrete block (light block) is the light and porous building material. It has light keeping temperature cant burn and other advantages. It can be made into many kinds of blocks(for example:600×200×100,80×80×180,240×115×53,600×200×125),they could be used industry building and common building. They are more and more popular in the world. In the future, they will replace the Clay brick completely.

Areated concrete common conception Common concrete density is usually 1600-2400kg/m3, but Areated concrete are 500kg/m3,600kg/m3,700kg/m3.It has not the big grain, main use silicon material (for example: coal ash, sand, stone dust and others), through making the material small for example sand, they can be used directly if has enough degree of small (for example coal ash. Mixing calcium material lime cement water to a special slop, then add the aluminium dust and the additive. Make the aluminium dust and the special slop have a Chemical reflect. Then produce Hydrogen to make the concrete slop to expanding or swell foam. Next, put them into the curing room to concreting cutting steaming curing, last, there will become the light brick; the porous rate is 70-80%.

Advantages

·         light weight ,Areated concrete density is usually 400-700kg/m3,(according the market in produce ),same as 1/3 of clay brick and  1/5 common concrete. So use the Light brick can reduce the weight of the build more,and also reduce the  beam of roof and pillar press best.then you can see,it can save the material and cost,it also fighting shaking.

·         keeping temperature It has many are porous,the delivery hearting coefficient is 0.9-0.22W/(mk),the same as  1/4 or 1/5 of clay brick,so it is best  materials now in the world.
