摘要: 为有效处理和利用固体废弃物,本文研究了用钙系膨胀剂,高炉矿渣水泥以及采用吸水率较小的再生骨料抑制碱骨料反应,尝试制备强度为30 MPa的再生骨料混凝土.并对其耐久性能做了试验研究.试验结果表明:再生骨料混凝土在强度以及耐久性能方面显示出与普通混凝土几乎相同的性能,并用钙系膨胀剂,高炉矿渣水泥以及采用吸水率较小的再生骨料,在解决再生骨料混凝土耐久性方面能够取得较好的效果.

Abstract: Strength grade C30 of recycled aggregate that was one of effective methods to dispose waste solid was fabricated with Ca series expanding agent, and blast furnace slag cement and low absorption recycled aggregate used to restrain alkali-aggregate reaction.The durable experiment shows that the strength and durability compared ordinary concrete with recycled aggregate concrete both display the same properties and Ca series expanding agent, blast furnace slag cement, and small water absorption play a good effect on durability of recycled aggregate concrete.
