Superfine calcium carbonate doping technology for improving appearance quality of concrete
The invention discloses a superfine calcium carbonate doping technology for improving the appearance quality of concrete, and relates to the technical field of superfine calcium carbonate. When the erosion-resistant concrete is prepared, the superfine calcium carbonate is doped, micro-pores in the concrete can be filled with fine particles of the superfine calcium carbonate powder, so that the pore structure of the concrete is refined, the appearance quality of a concrete member is improved, the micro-pores in the concrete can be filled with the fine particles of the superfine calcium carbonate powder, and the corrosion resistance of the concrete member is improved. The surface of the concrete is smoother and more uniform, the concrete is more attractive, the compactness and durability of the concrete can be improved by refining the pore structure of the concrete and doping the superfine calcium carbonate powder, formation of pores and cracks in the concrete can be reduced, and therefore the impermeability, freeze-thaw resistance and durability of the concrete are improved. When the mixing amount of the superfine calcium carbonate powder is 20% and the fineness is 400 meshes, the superfine calcium carbonate powder is mixed into the concrete, so that the pore structure of the concrete can be effectively refined, the appearance quality of a concrete member is improved, and meanwhile, the mechanical property of the concrete is ensured not to decline.
一种提升混凝土外观质量的超细碳酸钙掺入技术，涉及超细碳酸钙技术领域；在制备耐侵蚀混凝土时掺入超细碳酸钙，超细碳酸钙粉的微细颗粒可以填充混凝土中的微观孔隙，从而细化混凝土的孔结构，改善混凝土构件的外观质量，由于超细碳酸钙粉的细小颗粒可以填充混凝土中的微观空隙，使混凝土表面更加光滑和均匀，使其更具美观性，且通过细化混凝土的孔结构，掺入超细碳酸钙粉可以提高混凝土的密实性和耐久性，这有助于减少混凝土中的孔隙和裂缝的形成，从而提高混凝土的抗渗性、抗冻融性和耐久性；且当超细碳酸钙粉掺量为20％，细度为400目时，掺入到混凝土中可以有效细化混凝土孔结构，改善混凝土构件外观质量，同时保证混凝土的力学性能不衰退。
