矿物掺合料对预拌砂浆性能的影响研究

研究了粉煤灰、矿渣等矿物掺合料单掺及双掺对预拌砂浆工作性能的影响。试验结果显示：单掺粉煤灰0%～60%时,随着掺量的增大,砂浆稠度增大,和易性增强;单掺矿渣0%～60%时,随着掺量的增大,砂浆稠度有一定提高,但比同掺量的粉煤灰要小,且掺量大时出现泌水现象;双掺时,能改善砂浆和易性,同时还具有复合增强效应,使两种矿物掺合料性能上的优势得以互补。

Study about the influence of mineral materials on properties of ready mixed mortar

The article has researched the workability and strength about ready mixed mortar with fly ash or slag content,or fly ash and slag content.The results indicate that： while fly ash content is 0% ~60%,workability is higher as the content increasing,while slag content is 0% ~60%,workability is better than cement mortar,but worse than fly ash in the same content,and appear bleeding when the content is high,while fly ash and slag in mortar,workability and strength are improving,shows the two mineral materials can help each other in advantage.
