摘要
利用废砖粉作为矿物掺合料分别取代10%、20%和30%水泥量制备干粉砂浆,通过对干粉砂浆的28d抗压强度、稠度、保水率和14d拉伸黏结强度等性能研究。结果表明:废砖粉具有一定的水化活性,可以作为矿物掺合料制备干粉砂浆。
This paper studies the performance of dry-mixed mortar prepared with waste brick powder which respec-tively replacing 10%, 20% and 30% of cement amount. The performance study includes the compressive strength onday 28, the fluidity, water retentivity and tensile bond strength on day 14. The results show that waste brick powderis with certain hydration activity and can be used as mineral admixture for preparing dry-mixed mortar.
