Performance Test on Road Cement Concrete by Machine-made Sand

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.
