机制砂混凝土在高速公路上的应用研究

Research on application of manufactured sand concrete in expressways

针对天然砂资源逐步减少,质量日益下降,难以满足建筑用砂持续发展这一现实情况,详细介绍了采用机制砂进行混凝土配合比的设计及配制工艺,对节约社会资源、可持续发展等方面有着十分重要的意义。

Aiming at the fact with gradual reduction of natural sand resource, the degeneration of its quality, and unsatisfied supply for sustainable development of building sand, the paper introduces the design for the concrete mixture proportion with manufactured sand, and its mixing craft, so as to have the significance for saving the social resources and sustainable development.
