Alkali-activated coal gangue concrete and preparation method thereof
The invention discloses alkali-activated coal gangue concrete and a preparation method thereof. The alkali-activated coal gangue concrete is prepared from the following materials in parts by weight: 20-30 parts of coal gangue blocks, 25-35 parts of lightweight aggregate, 30-40 parts of sand, 1-3 parts of an alkali activator, 1-3 parts of a water reducing agent and a plurality of parts of a water source. According to the alkali-activated coal gangue concrete and the preparation method thereof, in the pretreatment process, through high-temperature calcination, a layered structure and a crystal structure of the alkali-activated coal gangue concrete can be partially damaged, and at the moment, a mineral structure is in a loose and porous state, and a metastable structure with multiple internal broken bonds and a large specific surface area is achieved; the calcined coal gangue is in a metastable state, main structural bonds of the calcined coal gangue are Si-O bonds and A1-O bonds, later treatment is facilitated, the purpose of effectively improving the compressive strength of the alkali-activated coal gangue concrete can be achieved by filling the coal gangue powder, meanwhile, during production, generated waste is treated through an effective means, and the production cost is reduced. The pollution to the environment is reduced.
本发明公开了一种碱激活煤矸石混凝土及其制备方法，包括由以下材料的重量份的成分组成：煤矸石块体20‑30份量、轻骨料25‑35份量、砂30‑40份量、碱激发剂1‑3份量、减水剂1‑3份量以及水源若干份量。该碱激活煤矸石混凝土及其制备方法，设置有通过在预处理的过程中，通过高温进行煅烧，可对其层状结构和晶体结构部分被破坏，此时矿物结构处于疏松多孔态、内部断键多和比表面积大的亚稳定的结构；经煅烧的煤矸石处于亚稳定状态，其主要结构键是Si‑O键和A1一O键，方便后期进行处理，并且通过煤矸石粉末的填入，可有效的增高该碱激活煤矸石混凝土的抗压强度的目的，同时，在生产时，所产生的废弃物通过有效的手段进行处理，减少对环境的污染。
