摘　　要：以高岭土尾矿、煤矸石、粉煤灰为原料烧成的陶粒为骨料,掺入自行配制的新型共聚超塑化剂,解决了陶粒混凝土离析、骨料上浮等问题,配制出轻质高强陶粒混凝土。试验结果表明,当新型共聚超塑化剂掺量为1.0%时,混凝土具有最佳的流动性和黏聚性;随塑化剂掺量增大,含气量增大,混凝土表观密度逐渐减小,抗压强度先提高后降低,当掺量为1%时抗压强度达到最大。The article described that the new copolymer superplasticizer could solve the segregation and floating problem when preparing the light-weight and high-strength concrete with the kaolin tailings-gangue-fly ash haydite. The results show that the concrete with good fluxility and viscosity would have been made with. 1% new superplasticizer adwixture：with the increase of superplasticizer, air content increases,apparent density of concrete decreases gradually, compressive strength first improves the decreases,the compressive srtength reaches the maximum when the dosage is 1%.
