摘要
试验采用碎石和高强页岩陶粒配制不同集料组成的混合集料混凝土并研究其力学性能。试验表明:混合集料混凝土的抗劈拉强度、弹性模量和表观密度随碎石取代率增加而增大,最佳碎石取代率80%时混凝土抗压强度和比强度达到最高。
The mechanical properties of combined aggregate concrete incorporated different proportion crushed stone and high strength expanded shale are studied in the paper. The test showed that the splitting tensile strength, elastic modulus and apparent density increase with the increasing amounts of crushed stone. The property of concrete made from 80% crushed stone and 20% expanded shale meet the highest compressed strength and strength to density ratio.
