Anchor shotcrete based on coal gangue and preparation method of anchor shotcrete
The invention relates to the technical field of anchoring and shotcreting concrete, and particularly provides anchoring and shotcreting concrete based on coal gangue and a preparation method of the anchoring and shotcreting concrete. The anchoring and shotcreting concrete is prepared from the following components in parts by weight: 100 to 140 parts of cement, 135 to 150 parts of coal gangue, 50 to 70 parts of water, 15 to 20 parts of admixture, 1 to 5 parts of calcium formate, 4 to 5 parts of water reducing agent, 5 to 9 parts of accelerator, 2 to 5 parts of nano zinc oxide, 3 to 5 parts of nano calcium silicate, 1 to 5 parts of nano silicon dioxide, 2 to 5 parts of nano aluminum silicate and 1 to 3 parts of nano titanium oxide. The anchoring and shotcreting concrete provided by the invention still has better mechanical properties while using the coal gangue as the aggregate.
本申请涉及锚喷混凝土技术领域，具体提供了一种基于煤矸石的锚喷混凝土及其制备方法。其中，所述锚喷混凝土包括以下重量份数的组分：水泥100‑140份，煤矸石135‑150份，水50‑70份，掺合料15‑20份，甲酸钙1‑5份，减水剂4‑5份，速凝剂5‑9份，纳米氧化锌2‑5份，纳米硅酸钙3‑5份，纳米二氧化硅1‑5份，纳米硅酸铝2‑5份，纳米氧化钛1‑3份。本申请提供的锚喷混凝土在使用煤矸石作为骨料的同时，依旧具有较佳的力学性能。
