| 摘 要： | 从混凝土致密堆积配比设计逻辑出发,研究了不同密度骨材(水库废弃淤泥烧结的骨材、天然骨材(石头)与实心钢珠为混凝土骨材,骨材密度分别为1.7、2.6和7.8kg.m-3)经致密配比的堆积,获得了轻质、常重与重质高性能混凝土的材料及其配比关系,对比分析了不同密度骨材混凝土特性包括新拌性质及硬固行为的影响.

| Abstract: | Based on the concrete design logic of the densified mixture design algorithm (DMDA),this paper investigated aggregates with different densities,i.e.,aggregates sintered by using a reservoir's waste sludge,natural aggregates (stones),and aggregates of solid steel balls,whose aggregate densities are 1.7,2.6,and 7.8 kg·m~(-3),respectively. Through the DMDA accumulation,lightweight,normal weight,and heavyweight high-performance concrete materials as well as their mixing ratios were obtained. The characteristics of these aggregate concretes,including the mixture properties and the effect of hardening behavior,were compared and analyzed. |
