摘要:
试验研究了低水灰比条件下,砂率对道面混凝土工作性、强度、耐磨性、抗水渗透性和抗冻性的影响规律.结果表明:砂率存在一个最佳值,此值下道面混凝土工作性最佳;随着砂率的增大,道面混凝土耐磨性能降低,抗渗性能提高,抗折强度、抗压强度和抗冻性均呈现先增大后减小的规律.最后,提出了低水灰比道面混凝土的合理砂率取值
Abstract:
Under the condition of low water-cement ratio, tests were carried out to study the effects of sand ratio on the workability, strength, wear resistance, impermeability and frost resistance of pavement concrete. It is proved that there exists a best sand ratio under which the pavement concrete performs best. With the increase of sand ratio, the wear resistance of pavement concrete deceases and the impermeability increases; the flexural strength, compressive strength and frost resistance all increase first and then decrease. In the end, it puts forward the rational sand ratio of pavement concrete in low water-cement ratio
