Strong acid corrosion resistant cement mortar and preparation method thereof
The invention provides strong acid corrosion resistant cement mortar and a preparation method thereof. The cement mortar is prepared from the following raw materials: cement, water, sand, fly ash, sodium silicate, carbon nano tubes, polypropylene fibers, a polycarboxylate superplasticizer and a dispersing agent. The cement mortar disclosed by the invention comprises the fly ash and the sodium water glass, and after the fly ash and the sodium water glass are added, a compact silicon dioxide structure can be formed in the cement mortar after curing, so that the reaction between the cement mortar and an acidic material is reduced, the erosion process of the acidic material is slowed down, and the effect of protecting concrete is achieved. The cement mortar further comprises the carbon nano tubes, the carbon nano tubes serve as a nano-sized reinforced fiber material, the pore structure of the concrete material can be effectively filled and improved due to the extremely fine particle size of the carbon nano tubes, and in addition, the internal microstructure of the concrete material can be densified due to the excellent mechanical property of the carbon nano tubes, so that the permeability of harmful substances of the concrete material is reduced, and the durability of the concrete material is improved.
本发明提供了一种抗强酸腐蚀的水泥砂浆及其制备方法，该水泥砂浆包括以下原料：水泥、水、砂、粉煤灰、钠水玻璃、碳纳米管、聚丙烯纤维、聚羧酸减水剂、分散剂。本发明的水泥砂浆，包括粉煤灰、钠水玻璃，添加粉煤灰、钠水玻璃后水泥砂浆在固化后内部会形成致密的二氧化硅结构，这样减少了水泥砂浆与酸性物质反应和减缓酸性物质侵蚀的进程，从而起到混凝土保护的作用；还包括碳纳米管，碳纳米管作为一种纳米尺寸的增强纤维材料，其极细的颗粒尺寸可以有效的填充和改善混凝土材料的孔隙结构，此外，碳纳米管本身的优异力学性能，可以使得混凝土材料的内部微观结构致密化，从而降低混凝土材料的抗有害性物质的渗透性，进而提高其耐久性能。
