Oil shale semicoke-based gel material, and preparation method and application of gel product
The invention relates to an oil shale semicoke-based gel material and a preparation method and application of a gel product, raw materials comprise a mineral precursor fine material, a crack-resistant component, a pore-adjusting component and a depolymerization component, and the mineral precursor fine material is prepared by grinding and mixing sintered oil shale semicoke and iron furnace hydrated slag. The raw materials are wide in distribution, convenient to obtain and low in price, and the requirements of large-scale and low-cost production can be met; compared with a traditional PO.52.5 high-strength cement binding material, the high-strength cement binding material has more excellent mechanical strength, fatigue resistance, saline-alkaline tolerance and volume stability; meanwhile, the oil shale semi-coke recycling field is widened, the oil shale semi-coke industrial chain is prolonged, the oil shale semi-coke application value is improved, resource and high-value utilization of oil shale semi-coke solid waste is powerfully promoted, and meanwhile the oil shale semi-coke can replace a cement binding material to be used for building high-strength concrete members and buildings; the consumption of a cement binding material with high carbon emission is reduced, the construction cost of concrete engineering is reduced, and the development of green and low-carbon concrete is promoted.
一种油页岩半焦基凝胶材料、凝胶产物的制备方法和应用，原料包括矿物前驱体细料、阻裂组分、调孔组分和解聚组分，所述矿物前驱体细料由烧成油页岩半焦和铁炉水凝渣磨碎后混合而成。各原材料分布广泛、获取方便、价格低廉，可满足规模化、低成本化生产的需求；与传统PO.52.5高强度水泥胶凝材料相比，具有更加优异的力学强度、抗疲劳、耐盐碱和体积稳定性能；同时拓宽油页岩半焦再利用领域、延长油页岩半焦产业链、提高油页岩半焦应用价值，将有力助推油页岩半焦固废的资源化、高值化利用，同时也能在替代水泥胶凝材料用于高强度混凝土构件、建筑的建造，减少高碳排放的水泥胶凝材料的消耗，降低混凝土工程造价，助力绿色、低碳混凝土的发展。
