摘要
介绍了用人工砂(包括石屑)试配高强混凝土以及人工砂在预应力高强混凝土管桩生产中应用的情况.试验结果表明,利用人工砂替代洁净的天然砂,可以提高混凝土的强度,改善混凝土的和易性,生产出的预应力高强混凝土管桩可以达到国家标准GB13476—1999的要求.
Preparation of high strength concrete with stone sand （stone screenings） and the application of the stone sand in the PHC pipe pile production are presented. The results show that when the stone sand substitutes for the natural sand, the strength of the concrete increases and the workability of the fresh concrete is improved. The properties of PHC pipe pile can comply with the requirements set forth in GB 13476-1999.
