| 摘 要： | 在高品质再生骨料制备过程中不可避免地会产生15%左右的微粉.该微粉的有效利用对于废弃混凝土的资源化和环境保护具有重要意义.研究了处理方法和掺量对胶砂抗压强度的影响.结果表明,该微粉掺量低于30%时,其活性与II级粉煤灰基本相同;经热处理后,活性明显提高,在600 ℃达到最高.

| Abstract: | About 15% powder is produced during the preparation of high quality recycled concrete aggregate. The effective utilization of this powder is significance to environment protection and recycling of waste concrete. The influence of powder content and treatment method on compressive strength of mortar are investigated in this paper.The results indicate that when the powder content is lower than 30%,the activity is same as fly-ash,the activity of the powder becomes considerable higher after heat treatment and r... |
