摘要
为探究湿拌砂浆性能与机制砂石粉等各组分含量之间的关系,文中针对机制砂石粉含量对湿拌砂浆性能的影响进行研究.结果表明,粉煤灰掺加 7%～14%,增稠保水剂掺加 1.2%～1.8%,引气剂掺加 0.2%～0.4%,机制砂石粉含量在 5%～15%时,效果较好.通过设计正交试验,优化材料配比,粉煤灰、增稠保水剂、引气剂和机制砂石粉掺量分别为 12%、1.8%、0.2%和 10%时,湿拌砂浆性能优良,该湿拌砂浆各项性能均高于标准要求.
Abstract
In order to explore the relationship between the properties of wet mixed mortar and the content of machine-made sand and gravel powder,the influence of machine-made sand and gravel powder content on the properties of wet mixed mortar was studied in this paper.The results show that the best effect is obtained when fly ash is added 7%～14%,the best effect is obtained when thickening water retaining agent is added 1.2%～1.8%,the best effect is obtained when air entraining agent is added 0.2%～0.4%,and the best effect is obtained when the content of mechanical sand powder is 5%～15%.Through the design of orthogonal test to optimize the material ratio,the wet mixed mortar has good performance when the content of fly ash,thickening water retaining agent,air entraining agent and mechanical sand powder is 12%,1.8%,0.2%and 10%,respectively.The properties of the prepared wet mixed mortar are higher than the standard level.
