以C80机制砂混凝土的配制和工作性能、抗压强度测试为基础,研究了外加剂掺量、水胶比、胶凝材料用量、机制砂种类以及机制砂砂率等因素对于C80机制砂混凝土工作性能和抗压强度的影响。结果表明:外加剂掺量、机制砂的种类和砂率对于C80机制砂混凝土的影响主要在工作性能方面,对于抗压强度影响不明显。在此基础上确定了C80机制砂混凝土的配合比,并具有良好的耐久性能。
Based on the preparation, working performance and compressive strength test of C80 concrete, the effects of admixture dosage, water-binder ratio, cementitious material dosage, type of engineered sand and mechanism sand ratio on the performance of C80 engineered concrete Impact of performance and compressive strength. The results show that: the admixture dosage, the type of sand and sand rate of C80 for the impact of concrete mainly in the performance of the concrete performance, the compressive strength of the impact is not obvious. On this basis, the proportion of C80 sand made of concrete is determined and has good durability.
