摘要
根据采空区注浆技术要求及特点,系统研究高掺量粉煤灰水泥浆材(粉煤灰掺量大于40%)、水泥粘土浆材、纯灰及水泥含量小于10%浆材等的工程特性及其应用于建筑下采空塌陷区地基注浆治理的适宜性,在分析采空区注浆各技术参数与配合比之间关系后推荐了最佳配合比设计及参数。
According to the technical requirements and characteristics of the grouting mortars used in abandoned mines,systematic researches are carried out on the engineering properties of the grouting mortar with high fly ash content(>40%),cement-clay mortar,pure cement mortar and mortar with cement content less than 10% as well as their applicability to the treatment of abandoned minesAnd an optimum mixing ratio and its parameters are recommended after the relationship between the technical parameters of the grouting mortars and mixing ratio being analyzed
