Anti-corrosion and anti-crack concrete material for mass concrete engineering
The invention belongs to an anti-corrosion and anti-crack concrete material for mass concrete engineering. The components and the parts by mass are as follows: 225-378 parts of high-iron phase cement; 5 to 12 parts of fluoroaluminate cement; 158 to 215 parts of a ternary component admixture; 936 to 1077 parts of a three-grade coarse aggregate; 630 to 837 parts of second-grade fine aggregate; the initial slump of the prepared concrete material is 180-210 mm, the compressive strength at 56 days is rich by 10%-15%, the hydration heat at 7 days is 170-210 kJ/kg, the adiabatic temperature rise is lower than 50 DEG C, the electric flux is 600-700 DEG C, the chloride ion diffusion coefficient is lower than 1.8 * 10 <-12 > m < 2 >/s, the sulfate corrosion resistance grade is higher than KS90, the shrinkage value is lower than 300 [mu] m/m, and the concrete material can be widely applied to the field of concrete construction. The durability of corrosion resistance, crack resistance and the like of a C45-C80 mass concrete structure in severe environments such as high corrosion and the like is improved, and the service life of the C45-C80 mass concrete structure is prolonged.
本发明属于一种大体积混凝土工程用抗蚀、抗裂混凝土材料；组分和质量份数为：高铁相水泥225～378份；氟铝酸盐水泥5～12份；三元组分掺和料158～215份；三级配粗集料936～1077份；二级配细集料630～837份；制备的混凝土材料初始坍落度在180～210mm，56d抗压强度均富裕10％～15％，7d水化热介于170～210kJ/kg，绝热温升低于50℃，电通量介于600～700C，氯离子扩散系数低于1.8×10‑12m2/s，抗硫酸盐侵蚀等级均高于KS90，收缩值低于300μm/m，提升了高腐蚀等严酷环境下C45～C80大体积混凝土结构的抗蚀、抗裂等耐久性能及服役寿命。
