摘要
砂是预拌砂浆的重要组成部分,本文主要研究了不同比列的混合砂对预拌砂浆水灰比、和易性、保水性、强度等性能的影响。对预拌砂浆的配制、生产提供参考。
Sand is one of the key componens for ready mixed mortar, Effects of W/C, workability, water retention, and strength for reand mixed mortar of different snd mixing rate were mainly studied.Testing result showed that:when at the same consistency, as the content of manufactured sand increasing, W/C reducing, density increasing, workability improving;compressive strength increasing, while keep stable after 70%.Provide a reference for mixing and production of ready mixed mortar
