Preparation method of steel fiber reinforced and toughened spontaneous combustion coal gangue aggregate concrete
The invention discloses steel fiber reinforced and toughened spontaneous combustion coal gangue aggregate concrete and a preparation method thereof, and belongs to the field of resource utilization of solid waste building materials and the field of composite materials. The raw materials comprise wave shearing type steel fibers, a composite cementing material, spontaneous combustion coal gangue coarse and fine aggregate, a chemical additive and water. According to the invention, spontaneous combustion coal gangue coarse and fine aggregates are used for replacing natural aggregates to prepare concrete, and steel fibers are added for toughening and strengthening the concrete, so that a novel composite material with light self weight, high strength and good toughness is obtained. The method is simple in process, has the advantages of saving resources and recycling solid wastes, and can remarkably improve the tensile strength, bending resistance and impact resistance of the spontaneous combustion coal gangue aggregate concrete.
本发明公开了一种钢纤维增强增韧自燃煤矸石集料混凝土及其制备方法，属于固废建材资源化利用领域和复合材料领域。原材料包括波浪剪切型钢纤维、复合胶凝材料、自燃煤矸石粗细集料、化学外加剂和水。本发明使用自燃煤矸石粗细集料取代天然集料制备混凝土，并添加钢纤维对其进行增韧增强，得到一种自重小、强度高、韧性好的一种新型复合材料。本发明工序简单，具有节省资源和固废再利用的优势，能显著改善自燃煤矸石集料混凝土的抗拉、抗弯以及抗冲击性能。
