摘要
选用优质的常规材料,通过低水胶比,低胶凝材料用量,成功地制备了流动性优良,抗压强度超过60 MPa,耐久性优异的高性能混凝土。研究的内容主要包括高性能混凝土的配合比设计,以及抗压强度、劈裂抗拉强度、抗折强度、轴心抗压强度、弹性模量等力学性能;同时还进行了电通量、抗硫酸盐侵蚀等耐久性研究。
The conventional materials with high quality,low water binder ratio （W/B）and low binder content were selected to produce HPC with required high durability, perfect workability, and strength level of C60. The studied main con- tents include high performance concrete mix design and mechanical properties such as compressive strength, indirect tensile strength,flexural strength,axial compressive strength;elastic modulus;a study was made of such durability as rapid chloride permeability test results and sulphate resistance ,etc.
