Statistical analysis on the basic mechanical properties of aerated ceramsite concrete
The requirements on lightweight,structural strength,and high stability on material properties have to be met for aerated ceramsite concrete(ACC)when using as insulation material in building's exterior wall or the prefabricated wall panels.In this paper,several batches of ceramisite foam concrete were prepared by physical foaming with ceramisite from building waste soil as aggregate,the probability distribution of cube compressive strength,basic mechanical property parameters and their relationships of ceramsite foam concrete are studied by test statistics.The results indicate that,the cubic compressive strength preferably follows a logarithmic normal distribution that the coefficient of fitting determination is up to 0.997.A good linear relationship exists between the axial compressive strength and the cubic compressive strength,and the conversion factor is between 0.76-0.99.Comparatively,the splitting tensile strength and cubic compressive strength exhibits a power function relationship.Analyzing from the whole samples,the cubic compressive strength stably remains from 5.9-7.6 MPa.In addition,the dispersion of tensile strength values is relatively smaller for samples that the cubic compressive strength value is not more than 7.5 MPa.
