Ultra-high performance concrete and preparation method thereof
The invention relates to the technical field of ultra-high performance concrete, and particularly discloses ultra-high performance concrete and a preparation method thereof. The ultra-high performance concrete is prepared from the following raw materials in parts by weight: 44.4-50 parts of cement; 50 to 55.6 parts of steel slag powder; 0.25 to 3.6 parts of an exciting agent; 41.2 to 92.5 parts of quartz sand; 92.5 to 138.8 parts of steel slag sand; 8-10 parts of fly ash; 22 to 28 parts of silica fume; 20 to 30 parts of water; 2.8 to 3.2 parts of a water reducing agent; the preparation method comprises the following steps: uniformly mixing all the raw materials, and continuously stirring for 5-8 minutes to obtain the ultra-high performance concrete. The product disclosed by the invention can be used as a building raw material of a bearing structure and an anti-explosion structure, and has the advantages of high strength, low cost and small pollution; in addition, the preparation method has the advantages that operation is simple, and raw materials are easy to obtain.
本申请涉及超高性能混凝土的技术领域，具体公开了一种超高性能混凝土及其制备方法。该超高性能混凝土所用原料包括以下重量份的组分：水泥44.4‑50份；钢渣粉50‑55.6份；激发剂0.25‑3.6份；石英砂41.2‑92.5份；钢渣砂92.5‑138.8份；粉煤灰8‑10份；硅灰22‑28份；水20‑30份和减水剂2.8‑3.2份；其制备方法为：将全部原料混合均匀，持续搅拌5‑8min后得到超高性能混凝土。本申请的产品可作为承重结构、抗爆结构的建筑原材料，其具有强度高、成本低、污染小的优点；另外，本申请的制备方法具有操作简单、原料易得的优点。
