摘　　要：试验采用聚苯颗粒、粉煤灰陶粒、普通水泥、粉煤灰、硅灰、外加剂等原材料来配制超轻混凝土。配制采用正交设计,以聚苯颗粒、粉煤灰陶粒、粉煤灰为变量因子,通过对抗压强度、干表观密度等试验数据分析,选取可用于承重构件的最佳配合比,此时粉煤灰陶粒体积掺量为40%,聚苯颗粒体积掺量为25%,粉煤灰胶凝材料质量掺量为25%。The experiment used polybenzene particles,lytag,ordinary cement,fly ash,silica fume,admixture and other raw materials to prepare super-light weight concrete.The orthogonal design was adopted for the preparation,and polybenzene particles,lytag and fly ash were used as variable factors.Through the analysis of test data such as compressive strength and dry apparent density,the optimal mix proportion which could be used for load-bearing components was selected.At this time,the volume content of lytag was 40%,the volume content of polybenzene particles was 25%,and the mass content of fly ash cementification material was 25%.
