摘要
利用钢渣、粉煤灰做路面基层材料可大量利用工业废渣,减少天然石料的开采,是一种生态建筑材料。文章主要研究了钢渣、粉煤灰的路用性能,其中包括配合比、无侧限抗压强度、劈裂抗拉强度、回弹模量等常用性能,通过试验比较,证明钢渣与粉煤灰组合完全可以做道路基层使用。
Making use of steel - slag and fly - ash for the material of base course can utilizes in large the industrial residue waste, reduce the exploitation of natural stones, so they can be acted as a composite building material for environmental proteetion. This article analyzes mainly the mad performance of both materials, includingmix proportioning, unconfined compressive strength, tensile splitting strength, modulus of resilience, etc. A comparison of tests indicates that these combined materials can be used perfectly for the base course of pavement.
