摘要
介绍开发天然珍珠岩用作高强、高性能混凝土掺合料的实验研究 ,其结果表明在强度等级为 C5 0～ C80的高强、高性能混凝土中掺入珍珠岩磨细粉等量替代高标号水泥 10 %～ 2 0 %不仅提高混凝土拌合物的工作性 ,还可使混凝土后期抗压强度增长约 2 0 % ,同时具有可观的经济效益和深远的社会意义 .
This paper introduces natural pearlite to a new industrial use mineral admixture in high strength concrete (HSC) and high performance concrete (HPC).Based on experimental investigation,authors explained the method of mineral admixture making from pearlite,displayed the better result by using the mineral admixture in HPC,which is increasing fluency of concrete mixture?strength in late period and durability of HPC.
