机制砂率和石粉对人工砂砂浆抗渗性能的影响
Effect of manufactured sand ratio and limestone on the impermeability of manufactured sand mortar
摘要
Abstract
In order to achieve high performance application of manufactured sand,the mix proportions of manufactured sand mortar (MSM) were designed with the water-powder of 0.42,using mixed sand with different manufactured sand ratio and mixing limestone to replace part of cement,and the impermeability of MSM was experimentally studied.The mechanism was investigated by the pore size distribution and average porosity size of MSM.The study results show that,with the increase of manufactured sand ratio and limestone content,the impermeability of MSM increases firstly,and then decreases.When the manufactured sand ratio is 66.7％,and the limestone content is 10％,the impermeability of MSM reaches the best.关键词
