摘要
海底管道加重混凝土层主要起加重和机械保护作用,为满足混凝土表观密度、强度和工作性等几方面的设计要求。研究了铁矿石和铁矿砂重骨料不同掺量、不同水泥用量、不同砂率和聚丙烯纤维掺量对加重混凝土性能的影响。
Concrete is coated around the submarine pipeline in order to weight the line and keep it from being damaged.This study discusses the design demands of the concrete in density and compressive strength and operating performance.The influence of different content of iron ore, cement,polypropylene fiber and the sand ratio on the weight concrete performance is also studied in this paper.
