Superfine calcium carbonate erosion-resistant concrete with optimized pore structure and method thereof
The invention discloses superfine calcium carbonate erosion-resistant concrete with an optimized pore structure. The superfine calcium carbonate erosion-resistant concrete is prepared from cement, an admixture, fine aggregate, gravel, water, a water reducing agent, a retarder, a thickening agent and a defoaming agent, according to the prepared superfine calcium carbonate erosion-resistant concrete, on one hand, powder grading is optimized through superfine calcium carbonate powder from the perspective of raw materials, the internal pore structure of the concrete is improved, on the other hand, on the perspective of the technology, the technology of the concrete from the flow state to the whole component process is controlled, material and technology synergistic matching is provided, and the comprehensive performance of the concrete is improved. The appearance quality of the concrete member can be adjusted and controlled under the combined action; when the erosion-resistant concrete is prepared, the surface brightness of the concrete can be improved by doping the superfine calcium carbonate with snow white appearance into the concrete, and the 400-mesh calcium carbonate powder is added into the concrete, so that the number of pores can be effectively reduced, the pore structure can be optimized, and the appearance and the working performance of the concrete can be well improved.
一种优化气孔结构的超细碳酸钙耐侵蚀混凝土，其通过水泥、掺合料、细骨料、碎石、水、减水剂、缓凝剂、增稠剂和消泡剂为原料制备而成；本发明制备本发明制备而成的超细碳酸钙耐侵蚀混凝土，一方面从原材料角度出发利用超细碳酸钙粉优化粉料级配，改善混凝土内部孔结构，另一方面从工艺角度出发，把控混凝土从流态到整体构件过程的工艺，提出材料和工艺协同匹配，共同作用实现混凝土构件外观质量的可调可控；本发明在制备耐侵蚀混凝土时，通过向混凝土内掺入外观雪白的超细碳酸钙可改善混凝土表面亮度，且选用400目碳酸钙粉添加到混凝土中可有效降低气孔数量，优化气孔结构，对混凝土外观和工作性能有较好的改善作用。
