粉煤灰对孔道压浆料稳定性的影响分析
摘要
Abstract
Fly ash is the most widely used mineral admixture in pore grouting.By studying the process of adjusting the proportion of different batches of fly ash in the production process of channel grout,this paper summarizes the influence of fly ash content and density on the performance of channel grout.The results show that fly ash can promote the fluidity of channel grout,and the higher the content of fly ash is,the stronger the fluidity is;too high content of fly ash will increase the setting time,decrease the strength,and the maximum content should not be more than 25%;too high or too low amount of fly ash will lead to partial floating or precipitation in the channel grouting slurry,affecting the stability of the channel grouting slurry.The density of fly ash affects the suitable amount of fly ash in the channel grouting material,and the higher the density is,the lower the suitable content is.关键词
