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。
