摘　　要：泡粒混凝土是一种以聚苯乙烯发泡颗粒、水泥、水、发泡剂为主要成分的节能建筑材料。采用正交试验法考虑粉煤灰掺量、苯粒含量、水灰比、湿密度四个影响因素,各因素确定五个水平,以流值、抗压强度、导热系数为评价指标,研究了各因素对上述三个指标的影响规律。综合平衡各因素水平对评价指标的影响,确定了一种较为合理的泡粒混凝土配合比方案。Foamed particles concrete is a kind of building energy- saving materials,which main components are foamed particles of polystyrene cement,water and foaming agent.The influence rules of three indicator to every factor are researched by orthogonal experiment considering four influence factor which include the amount of fly ash the volume percentage of particles of polystyrene,water cement ratio,wet density and every factor has five level.A reasonable mix proportion is confirmed by considering the influence of every factor to evaluation index.
