钢筋混凝土是以普通硅酸盐水泥的水化物作为粘结剂并结合一定级配的骨料如碎石和钢筋而制成的一种复合材料。在钢筋混凝土的腐蚀中,骨料的影响较小,故只对水泥和钢筋进行讨论。普通硅酸盐水泥硬化制品是由约占50%的水合硅酸钙凝胶(3CuO·SiO_2·H_2O)、
Reinforced concrete is a composite material made of ordinary Portland cement hydrate as a binder and combined with a certain graded aggregate such as gravel and steel. In the corrosion of reinforced concrete, aggregate less affected, so only the cement and steel are discussed. Ordinary Portland cement hardened products is composed of about 50% of the hydrated calcium silicate gel (3CuO · SiO 2 · H 2 O)
