Sandstone waste slag water stabilizing material as well as preparation method and application thereof
The invention provides a sandstone waste slag water stabilizing material as well as a preparation method and application thereof. The sandstone waste slag water stabilizing material is prepared from coarse aggregate, fine aggregate and cement, wherein the coarse aggregate is continuous graded broken stone with the particle size of 4.75 to 31.5 mm; the fine aggregate is sandstone waste slag with the particle size of 0-4.75 mm, and in the coarse aggregate and the fine aggregate, the specific weight percentage of each material is as follows: 15-17% of continuous graded broken stone with the particle size of 4.75-9.5 mm; the proportion of the continuous graded broken stone with the particle size of 9.5 to 19.0 mm is 33 to 35 percent; the proportion of the continuously graded broken stones with the particle size of 19 to 26.5 mm is 23 to 25 percent; and the fine aggregate with the particle size of 0 to 4.75 mm accounts for 25 to 27 percent. The waste slag generated in the engineering construction process is used for replacing part of natural gravel aggregate, and the specific material proportion is adjusted, so that the performance of the cement water stabilizing material reaches the standard, the problems of lack of flooring and the like are partially solved, and meanwhile, the environmental protection problems of land occupation of a slag yard and the like are also partially solved.
本发明提供了一种砂岩弃渣水稳料及其制备方法和应用，包括粗集料、细集料和水泥组成；其中所述粗集料为4.75～31.5mm连续级配碎石；所述细集料为粒径为0～4.75mm的砂岩弃渣，所述粗集料和细集料中，各个物料具体的重量百分占比如下：粒径为4.75～9.5mm的连续级配碎石占比为15%～17%；粒径为9.5～19.0mm的连续级配碎石占比为33%～35%；粒径为19～26.5mm连续级配的碎石占比为23%～25%；0～4.75mm的细集料占比为25%～27%。利用工程建设过程中产生的弃渣来替代部分天然砂石骨料，通过针对性物料占比的调整，使得水泥水稳料性能达到规范标准，不仅部分解决了地材缺乏等问题，同时也部分解决了渣场占地等环保问题。
