摘　　要：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。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。The recycled aggregate is wrapped with a layer of hardened cement mortar, it canse significant differences in the strength of recycled aggregate apparent density, water absorption compared to natural aggregate.The aggregate water absorption, apparent density of aggregate are used to explore the relationship between the replacement rate, pulp content, apparent density and water absorption and how to use water to replace the projected rate of pulp content.

关 键 词：再生骨料 浆含量 再生骨料取代率 吸水率 表观密度
