Coal gangue roadbed material and preparation method thereof
The invention provides a coal gangue roadbed material and a preparation method thereof. The coal gangue roadbed material comprises the following components in parts by weight: a mixed solid material which comprises 2-5 parts of coal gangue granules, 0.5-3 parts of blast furnace slag, 0.5-3 parts of red mud powder and 1-2.5 parts of carbide slag; the dosage of the alkali activator accounts for 2-4% of the weight of the mixed solid material; 2.8 to 3.2 parts of water; the use amount of the polypropylene fiber accounts for 0.4-0.8% of the weight of the mixed solid material. The problems that in the prior art, resource utilization of solid waste is insufficient, and a low-cost method for improving roadbed frost heaving is lacked can be solved.
本发明提供了一种煤矸石路基材料及其制备方法。该煤矸石路基材料按重量份数计，包括：混合固料，混合固料包括：煤矸石粒料2～5份、高炉矿渣0.5～3份、赤泥粉料0.5～3份、电石渣1～2.5份；碱激发剂，碱激发剂的用量占混合固料重量的2～4％；水2.8～3.2份；聚丙烯纤维，聚丙烯纤维的用量占混合固料重量的4～8‰。本发明能够解决现有技术中固体废料资源化利用不足、以及缺乏低成本改良路基冻胀的方法的问题。
