Ecological ultra-high performance concrete and preparation method thereof
The invention relates to the field of building materials, and in particular, relates to ecological ultra-high performance concrete and a preparation method thereof. The ultra-high performance concrete provided by the invention comprises a cementing material, sand, water and a water reducing agent, wherein the cementing material comprises the following raw materials in parts by mass: 400-450 parts of Portland cement, 120-180 parts of a dehydrated phase, 120-180 parts of molybdenum tailings, 180-200 parts of stone powder and 180-200 parts of silica fume, wherein the dehydration phase is obtained by hydrating cement. According to the ultra-high performance concrete provided by the invention, the molybdenum tailings are used as a cementing material, so that the tailings are utilized in a high-valued manner, and the energy consumption of the ultra-high performance concrete is greatly reduced.
本申请涉及建筑材料领域，特别涉及一种生态型超高性能混凝土及其制备方法。本申请提供的超高性能混凝土包括胶凝材料、砂子、水和减水剂，其中，所述胶凝材料包括以下质量份的原料：硅酸盐水泥400‑450份，脱水相120‑180份，钼尾矿120‑180份，石粉180‑200份，硅灰180‑200份；所述脱水相由水泥水化得到。本申请提供的超高性能混凝土以钼尾矿作为胶凝材料，不仅使尾矿得到了高价值化利用，而且大大降低了超高性能混凝土的能耗。
