摘要
本文对目前废弃混凝土再生技术的研究做了论述,并指出了其中存在的一些问题。结合混凝土各组成部分的结构特点,提出了通过低温煅烧对废弃混凝土综合利用的新方法。在750℃温度条件下煅烧1h,可以实现水泥浆与骨料的分离。脱水后的水泥浆可以重新获得水化活性。得到的混凝土骨料可以满足使用要求。
The current research situation on the recycling technology of waste concrete and existing problems in application was summarized. Considering the structural characteristics of cement paste and aggregate, a new recycling technology through calcination is presented. The cement paste and aggregates could be separated at 750℃ for one hour. The dehydrated cement paste can have reactivity again, and the aggregates can meet the requirement of application.
