炉渣粉煤灰混凝土砌块的基本性能试验研究

The research on the basic performance tests of slag fly ash concrete block

介绍了炉渣粉煤灰混凝土砌块的原材料种类及性能,设计了6种不同试验配合比的炉渣粉煤灰混凝土砌块,分别进行了密度、抗压强度、冻融及导热系数试验,得出了炉渣粉煤灰混凝土砌块在不同配合比下的各基本性能指标。经过对比分析,炉渣粉煤灰混凝土砌块的密度约为1700 kg/m3,抗压强度大于10.0 MPa,导热系数约为0.298 W(/m·K),冻融试验结果满足规范要求。

The raw materials types and performance of slag fly ash concrete block were intreduced,the slag fly ash concrete blocks of 6 different test mix proportions respectively were designed in this paper, density test,compressive strength test,freezing and thawing test and coefficient of thermal conductivity test were carried out,and the basic performance indices of the slag fly ash concrete block under 6 kinds of different mix proportion were obtained. Through contrast analysis, unit weight of slag fly ash con- crete block is about 1700kg/m3, compressive strength is greater than 10.0MPa, thermal conductivity is about 0.298 W/ （m ·K） , freez- ing and thawing conditions can meet the requirements of specification.
