摘 要:介绍了人工砂(石矿尾屑和卵石砂)在高强度预应力混凝土管桩中的应用,并作了试验研究。结果表明,掺入一定量的人工砂不但可以提高混凝土的强度和性能,而且具有一定的经济优势。掺入人工砂生产出的管桩完全能满足工程施工需要,特别是对于年设计生产能力100万m管桩的生产单位,人工砂具有更大的应用价值。
Abstract: The application of artificial sand (stone chip tail sand and pebble) in high strength prestressed concrete piles is introduced, and some relative experimental studies are carried out. The results show that adding a certain amount of artificial sand can not only improve the strength and performance of concrete, but have some economic advantages. The piles with artificial sand can completely meet the requirements of engineering construction, especially for production companies whose the annual design production capacity is 1 million meter piles, artificial sand has greater application value.
