【摘要】 主要研究了采用普通水泥和高贝利特水泥(HBC)配制的混凝土及高性能混凝土的工作性、力学性能及抗裂性能。采用高贝利特水泥配制的混凝土坍落度损失远小于普通水泥混凝土;早期抗压强度较普通水泥混凝土偏低,但后期强度增幅较大;28d龄期抗拉强度均略高于普通水泥混凝土;并具有更好的抗裂能力。更多还原

【Abstract】 The workability,mechanical properties and cracking resistance of the high-belit cement concrete and high performance concrete and ordinary cement concrete were studied in this paper.The results show that the slump loss of high-belit cement concrete is much less than ordinary cement concrete,its early compressive strength is lower than ordinary cement concete,but its late strength enhances greatly,its tensile strength in 28d is higher than ordinary cement concrete,and its cracking resistance is better.更多还原
