Steam-cured alkali-activated slag concrete and preparation method thereof
The invention belongs to the technical field of building materials, and relates to steam-cured alkali-activated slag concrete and a preparation method thereof. When the steam-cured alkali-activated slag concrete is applied to engineering in alpine regions, the steam curing time is shortened by 1-2 hours, so that the characteristics of high strength, good freezing resistance and high chloride ion erosion resistance can be utilized, the quality of components is improved, and the steam-cured alkali-activated slag concrete is adapted to extreme weather conditions; besides, the problems of long forming and curing time and long construction period can be solved, the component steam curing and mold removal time is shortened, the mold turnover rate is greatly increased, the construction period is shortened, and the adverse effect caused by construction in winter is relieved; meanwhile, 20-30% of fly ash is doped to replace slag, and the problem of shrinkage cracking of the alkali-activated concrete is effectively solved by adopting a steam curing system; in addition, cement is not used for preparing the concrete, so that energy consumption and carbon emission are greatly reduced, and energy conservation and environmental protection are achieved; and river sand is replaced with machine-made sand, so that the usage amount of natural resources is reduced, the production cost is saved, and the steam-cured alkali-activated slag concrete has important significance on healthy and sustainable development of the building industry.
本发明属于建筑材料技术领域，涉及一种蒸养碱激发矿渣混凝土及其制备方法，在高寒地区工程中应用时，蒸养时间缩短了1‑2小时，不仅可以利用强度高、抗冻性好和抗氯离子侵蚀性能强的特点，提升构件的质量,适应极端气候条件，还可以解决成型养护时间和施工周期长的问题，缩短构件的蒸养、拆模时间，大幅增加模具周转率，缩短施工周期，缓解冬季施工带来的不利影响；同时，掺入20‑30％的粉煤灰取代矿渣，采用蒸养制度有效解决了碱激发混凝土收缩开裂的问题；另外，不使用水泥制备混凝土大大降低了能源消耗和碳排放量，节能环保，采用机制砂取代河砂，降低了自然资源的使用量，节约了生产成本，对建筑业的健康、可持续发展具有重要的意义。
