摘　　要：通过试验研究了不同细度模数的河砂及不同含泥量的砂石对混凝土性能的影响,并分析砂石质量的差异对混凝土经济性的影响,得出河砂细度模数及砂石含泥量不同对混凝土经济性的影响规律。根据这些规律实现混凝土配合比的优化并指导生产,以有效控制混凝土的质量。Study on the effect of different fineness modulus of sand and mud containing different amount of sand and stone on the concrete per- formance by experiments, analyze differences in the quality of sand and stone on the concrete economy, obtain the effect rule of different fineness modulus of sand and different amount mud-content of sand and stone on the economy of concrete, in accordance with these rules to achieve the optimization of concrete mix and to guide production and effective control over the quality of concrete.

关 键 词：砂石 含泥量 经济性
