Taoli sand seismic performance and insulation performance

Ceramsite concrete due to the quality of light, low elastic modulus, resistance to deformation performance is good, so has good seismic performance, ceramsite sand around a number of brick buildings are in different degrees by the earthquake. Although it is associated with building structure system, but the frac sand companies concrete has excellent seismic performance is also an important reason. 1976 Italian LiuLi area of strong earthquake with a magnitude 9, statistics show that the brick building damage rate was 40% ~ 40%, the frame structure of clay brick building the damage rate was 33%, and ceramsite concrete building damage rate is only 5%. Ceramsite ceramsite sand seismic performance thus, heat preservation, heat insulation frac sand due to internal porous, so it has good insulation, the thermal conductivity of concrete prepared with it, as a general rule, be 0.3 ~ 0.8 W/(mok), 1 ~ 2 times lower than the normal concrete. Ceramsite architecture has good thermal environment, according to the test for many times, ceramsite sand ceramsite concrete permeability resistance is better than that of ordinary concrete. With 20 mpa ceramsite concrete and ordinary concrete, for example, by comparing multiple tests, ordinary concrete impermeability index for B6, and can achieve B18 ceramsite concrete is to B25.
