BAIJIAN - Third party testing organization
Aggregate、 as the main raw material in concrete、 plays a skeleton and supporting role in buildings. When cement is mixed with water、 it becomes a thin paste. Without the addition of aggregates、 it will not be able to form and will be unusable、 affecting the quality of the project. Therefore、 aggregates are essential and important raw materials in construction. Usually、 the detection scope of coarse and fine aggregates by China Steel National Inspection involves: construction sand、 construction pebbles、 crushed stones、 fine aggregates、 coarse aggregates、 rocks、 etc. The testing items mainly include particle grading、 MB、 bulk density、 stone powder content、 mud content、 mud lump content、 water absorption、 alkali aggregate reaction、 apparent density、 chloride content、 sulfide and sulfate、 light matter、 organic matter、 fineness modulus、 mica content、 alkali activity、 porosity、 shell、 etc
