摘　　要：以高岭土尾矿-煤矸石-粉煤灰陶粒为骨料,研究不同水胶比、砂率等对陶粒混凝土性能的影响。结果表明,胶凝材料用量、砂率等对陶粒混凝土的干表观密度和导热系数影响明显,适当的胶凝材料用量和砂率是配制具有良好热工性能轻质高强陶粒混凝土的关键。The article described the effect of water-binder ratio and sand ratio on kaolin tailings-gangue-fly ash haydite concrete by testing. The＂ results shown that water-binder ratio and sand ratio had an effect on the dry apparent density and thermal conductivity of concrete and that the reasonable cementing material content and sand ratio were the key to prepare the light-weight and high-strength concrete with the better thert＇nal performance.
