摘　　要：针对广州地区目前河砂资源短缺的问题,通过试验对比研究了水灰比、砂率等对机制砂路面混凝土工作和力学性能的影响,并对比河砂混凝土,对其技术经济优势进行了分析。结果表明:用机制砂取代河砂也能配制出工作和力学性能优良的路面混凝土,其每m3混凝土直接节约材料成本43.4元,具有显著的技术经济效益。Aiming at the shortage of natural sand resource in architectural engineering in Guangzhou area, the effects of water - binder ratio and sand ratio on the working and mechanical performance of manufactured sand pavement concrete are investigated. Besides, its economic and technical advantages are analyzed comparing with river sand. The results indicate that the pavement con- crete with excellent working and mechanical performance can also be produced by using manufactured sand, and every cubic meters of concrete can save material cost by ￥43. 4 directly. It has the remarkable technical and economic benefits.
