A Japan construction material design office recently researched and developed one kind of new building material, this material not only hardened the speed to be quick, moreover the tensile strength was concretes 2.5 times. This new material is made by the carbon dioxide and the silica, the make bricks convenience is quick.stonebtb.com When construction, this material only need few the steel bar accessory material uses for to reinforce, may meet the construction need. The traditional building material concretes need 28 days to be able to harden achieve the design intensity, but this new material only needs 1 day to be possible to achieve. After these characteristics cause this material is very suitable to use for to construct the disaster, to reconstruct the construction, perhaps carries on the transformation strengthening works to the existing construction.Construction material withstands breeze blowing for a long time such as wind, sunlight, rain, corrosion and so on.The reasonability of building material is very big, the immediate influence to the project construction cost, usually the building materials expense accounts for the project total construction cost more than 50%, therefore when considers the technical performance, must give dual attention to the efficiency.
