Experimental Study on the Preparation of Recycled Fine Aggregate

Abstract

In this paper, the waste concrete is used to produce recycled fine aggregate, and then different mixing quantities are used to produce ordinary mortar by replacing artificial sand. The paper makes relevant studies on the influence of the recycled fine aggregate quantity on the performance of ordinary mortar. The studies show that it is feasible to produce ordinary mortar with a certain amount of recycled fine aggregate instead of artificial sand, which can meet the requirements of relevant standards, specifications and engineering.
