本项目通过三掺粉煤灰、粒化高炉矿渣、硅灰等取代部分水泥,再掺入一定量的抗裂防腐剂,通过三掺矿物掺合料及抗裂防腐剂共同作用下,充分发挥其互补效应,减少了水泥石的孔隙,提高了混凝土的密实度,优化配合比,配制改性高抗硫耐腐蚀混凝土。试验结果表明,掺入35%~40%的磨细粉煤灰和粒化高炉矿渣及4%~6%的硅灰能有效的提高混凝土抗氯离子渗透性能,抗硫酸盐侵蚀能力及抗压强度。 In this project, part of cement is replaced by three mixed fly ash, granulated blast furnace slag, silica fume and the like, then a certain amount of crack preservative is added, and under the joint action of three mixed mineral admixtures and crack preservative, Complementary effect, reducing the pores of cement stone, improve the density of concrete, optimize the mix, the preparation of modified high sulfur and corrosion-resistant concrete. The test results show that the incorporation of 35% to 40% of the fly ash and granulated blast furnace slag and 4% to 6% of silica fume can effectively improve the concrete resistance to chloride ion permeability, resistance to sulfate attack and compression strength.
