Early-strength ultrahigh-strong-alkali-activated coal gangue concrete and preparation method thereof
The invention provides early-strength ultrahigh-alkali-activated coal gangue concrete and a preparation method thereof, and belongs to the technical field of solid waste resource utilization and alkali-activated cementing materials, the concrete is prepared from calcined coal gangue fine aggregate or calcined coal gangue composite fine aggregate, slag, calcined coal gangue powder, an activator and steel fibers, the early-strength ultrahigh-alkali-activated coal gangue concrete is high in compressive strength and breaking strength, high in early strength, good in coal gangue aggregate-matrix interface bonding and compact in concrete matrix, and high-quality and resource utilization of coal gangue is facilitated. Combustion of carbon powder in the coal gangue fine aggregate can fully release heat energy, an industrial chain is formed with a power generation and heating system, harmless and zero-pollution utilization of the coal gangue is promoted, the utilization rate and additional value of the coal gangue are comprehensively improved, the problem that the coal gangue is difficult to treat is solved, and the problem of shortage of natural gravel aggregate is made up to a certain extent; the problem that traditional cement-based coal gangue mortar and concrete are low in strength is solved.
本发明提供了一种早强超高强碱激发煤矸石混凝土及其制备方法，属于固废资源化利用和碱激发胶凝材料技术领域，混凝土由煅烧煤矸石细骨料或者煅烧煤矸石复合细骨料、矿渣、煅烧煤矸石粉、激发剂和钢纤维制成，本发明的早强超高强碱激发煤矸石混凝土抗压和抗折强度高、早期强度高、煤矸石骨料‑基体界面结合好、混凝土基体密实，有利于实现煤矸石高质化、资源化利用。煤矸石细骨料中碳粉的燃烧可充分释放热能，同发电和供暖系统形成产业链，促进煤矸石无害化、零污染利用，全面提升煤矸石利用率和附加值，解决了煤矸石处理难的问题，在一定程度上弥补了天然砂石骨料短缺的问题，克服了传统水泥基煤矸石砂浆及混凝土强度较低的问题。
