再生骨料表面包裹着一层硬化水泥砂浆、导致再生骨料的强度和表观密度、吸水率与天然骨料相比差别很大。本文利用骨料的吸水率、表观密度这两个指标来探讨再生混凝土中再生骨料的取代率、浆含量、表观密度和吸水率的关系及如何利用吸水率、取代率来推算浆含量。
Recycled aggregate surface covered with a layer of hardened cement mortar, resulting in the strength and apparent density of recycled aggregate, water absorption and natural aggregate vary widely. In this paper, we use the two indexes of water absorption and apparent density of aggregates to discuss the relationship between the replacement rate, pulp content, apparent density and water absorption of recycled aggregate in recycled concrete and how to calculate the pulp content by using the rate of water absorption and the substitution rate .
