Environment-friendly water-resistant ultra-high performance concrete material and preparation method thereof
The invention provides an environment-friendly water-resistant ultra-high-performance concrete material. Each 1m < 3 > of the environment-friendly water-resistant ultra-high-performance concrete material is prepared from the following components: a cementing material, quartz sand, a polyhydroxy acid series high-performance water reducing agent and water, the cementing material is prepared from 390 to 750 kg of cement, 180 kg of calcined clay and 220 to 550 kg of dolomite powder; the use amount of the quartz sand is 100% of the mass of the cementing material, the use amount of the polyhydroxy acid series high-performance water reducing agent is 0.8-1% of the mass of the cementing material, and the mass ratio of the water to the cementing material is 0.2. The invention also provides a preparation method of the environment-friendly water-resistant ultra-high-performance concrete material, which comprises the following steps: stirring the cement, the calcined clay and the dolomite powder in a stirrer, adding the quartz sand, continuously stirring, adding the polyhydroxy acid-series high-performance water reducer solution, stirring into a plastic state, continuously stirring, filling into a mold, vibrating and compacting, and drying to obtain the environment-friendly water-resistant ultra-high-performance concrete material. And finally, curing. The environment-friendly water-resistant ultra-high performance concrete material prepared by the preparation method disclosed by the invention has good mechanical and water-resistant properties.
本发明提供了一种环保型耐水超高性能混凝土材料，每1m3的环保型耐水超高性能混凝土材料由以下组分制成：胶凝材料、石英砂、聚羟酸系高性能减水剂和水；胶凝材料的配比为水泥390‑750kg、煅烧粘土180kg、白云石粉220‑550kg；石英砂的用量是胶凝材料质量的100％，聚羟酸系高性能减水剂的用量是胶凝材料质量的0.8‑1％，水的质量和胶凝材料质量的比为0.2。还提供上述环保型耐水超高性能混凝土材料的制备方法，该方法为：将水泥、煅烧粘土和白云石粉放入搅拌机内搅拌，然后加入石英砂继续搅拌，再将聚羟酸系高性能减水剂溶液加入，搅拌成塑性状态，继续搅拌后装入模具中振捣密实，最后进行养护。本发明制备的环保型耐水超高性能混凝土材料具备良好的力学和耐水性能。
