摘要
机制砂配制水泥混凝土其力学性能略高于天然河砂配制的水泥混凝土,具有很好的路用性能,对机制砂配制水泥混凝土和天然河砂配制水泥混凝土进行了干缩性能对比试验,并对机制砂水泥混凝土机理讨论。以机制砂代替天然河砂配制水泥混凝土应用于路面工程,具有很好的经济社会效益。
The mechanical property of cement concrete by machine-made sand is better than that of cement concrete by natural sand, and the former is of good pavement performance. Then, a shrinkage performance contrast experiment has been done between the two kinds of cement concrete. The mechanism of cement concrete by machine-made sand was also discussed in the paper. In the author's opinion, the cement concrete by machine-made sand is of excellent economic and social effect instead of natural kind applied in pavement engineering.
