铅锌尾矿微粉在干混砂浆中的应用研究
Application of Lead-zinc Tailings Micro-powder in Dry-mixed mortar
摘要
Abstract
The modified lead-zinc tailings micro-powder was prepared by adding certain amount of chemical activator,which was made of the micro-powder of lead-zinc tailings with different specific surface after ball milling in Jiangxi province,it is used in M7.5 dry mixed plastering mortar instead of fly ash.The results show that the optimum grinding time is 8 min,and the chemical activity and water requirement ratio of the lead-zinc tailing powder can be improved by adding 1.0％silicate activator.The addition of lead-zinc tailings micro-powder into the mortar has almost no effect on the consistency and water retention of the dry-mixed mortar,when the content of lead-zinc tailings micro-powder is above 50％,the setting time and strength of mortar will be slightly reduced and the cohesion of mortar will be reduced.But still meet the performance requirements of mortar.关键词
