摘　　要：水泥胶砂是一种不含粗集料的特殊混凝土,参照混凝土的试验方法研究相同尺寸的水泥胶砂性能。根据机场道面水泥混凝土干硬性的特点,选择低水灰比干硬性水泥胶砂为研究对象并探讨含泥量对干硬性水泥胶砂强度和耐久性的影响,得出含泥量对干硬性水泥胶砂性能的影响规律,进而反映出细集料含泥量对干硬性水泥混凝土的影响。Cement mortar is a kind of special concrete without coarse aggregate, the same way studying concrete performance was used to study cement mortar in the same size.According to the harsh characteristics of airport pavement cement concrete, dry cement mortar of low wa- ter cement ratio was chose as research object,effect of sediment content on strength and durability of dry cement mortar was studied, the disci- pline of effect of sediment content on dry cement mortar was got,and then the reaction effect of sediment content of fine aggregate on harsh concrete was reflected.
