Full-coal-gangue quick-hardening early-strength concrete and preparation method thereof
The invention provides full-coal-gangue quick-hardening early-strength concrete and a preparation method thereof. The full-coal-gangue quick-hardening early-strength concrete is prepared from slag, coal ash, NaOH, water glass, water, coal gangue micro powder, fine coal gangue particles, coarse coal gangue particles and a water reducing agent. According to the invention, an advanced cementing technology is applied, coal gangue powder is used for replacing a cementing material and an exciting agent in an isometric manner, and coarse and fine coal gangue particles are used for completely replacing concrete gravel aggregate, so that the full-coal gangue quick-hardening early-strength concrete is prepared, waste is turned into wealth, and the economic value of coal gangue is remarkably improved; and the safety, economic and social problems caused by coal gangue accumulation of coal mine enterprises are relieved and even eliminated, operation is easy, cost is low, and the method has wide application prospects under the background of shortage of raw materials in the building material market.
本发明提供了一种全煤矸石快硬早强混凝土及其制备方法，该全煤矸石快硬早强混凝土包括矿渣、粉煤灰、NaOH、水玻璃、水、煤矸石微粉、细煤矸石颗粒、粗煤矸石颗粒、减水剂。本发明运用先进胶结技术，以煤矸石粉等体积替代胶凝材料和激发剂，以粗细煤矸石颗粒全部替代混凝土砂石骨料，实现制备全煤矸石快硬早强混凝土，变废为宝，显著提升煤矸石经济价值，减轻乃至消除煤矿企业因煤矸石堆积而引发的安全、经济和社会问题，操作简单，成本低廉，在建材市场原料紧缺的背景下，具有广阔的应用前景。
