陶粒轻质高强混凝土的试验研究

An experimental research on light-weighted and high-strengthed concrete of expanded fly ash aggregate

基于普通原材料和工业废渣,通过正交试验和普通成型工艺配制出抗压强度超过50 M Pa、表观密度1 950 kg/m3的轻质高强混凝土材料,并给出优选配比方案,归纳出轻质高强混凝土强度、强质比与胶水比的经验公式。

With the help of ordinary mixing method, a kind of light-weighted concrete with a compression resistance over 50 MPa and a density of 1 950 kg/m^3 is produced after orthogonal tests by using ordinary materials and residue of industrial wastes. The optimization mixing proportions are recommended while an empirical formula for the density of such light-weighted concrete and the ratio of hinder and water is introduced.
