摘要
研究了集料组成对次轻混凝土宏观性能的影响规律,通过调整集料组成配制出了密度在2 2 0 0kg/m3 左右,强度大于6 0MPa的次轻混凝土。结果表明,集料组成能明显地影响次轻混凝土的表观密度、抗压强度、抗拉强度和弹性模量。
In this paper, the influence of aggregate composition on the macro-performance of semi lightweight concrete was investigated. The results showed that aggregate composition could significantly affect the apparent density, compressive strength, split tensile strength and elastic modulus of semi-light weight concrete.
