摘　　要：混凝土中的骨料,特别是粗骨料对水泥的收缩起着约束作用,是混凝土内部阻抗水泥收缩的主要组分。然而粗细骨料作为一种地方性材料,其质量的稳定性相对较差。通过平板试验,研究骨料的品种、砂率、含泥量、体积含量等因素对混凝土早期抗裂性能的影响。The aggregate in a concrete,in particular,the coarse aggregate has a restriction on the contraction of the cement,which is the main component resisting the contraction of the cement in the concrete.Coarse and fine aggregate,however,as a local material,has a relative poor stability.In this paper,through the plate test,it is studied the effects of aggregate species,sand percentage,clay content,volume levels ect on the early anticracking of concrete.

关 键 词：骨料 混凝土抗裂性 平板试验
