摘　　要：混凝土的侵蚀实质是水泥石的侵蚀,而造成混凝土宏观破坏。高性能混凝土由于掺加了高效减水剂和大掺量超细掺合料并采用低水胶比配制,因而具有高密实度和优异的抗侵蚀性。The corrosion essence of the concrete is that corrosive materials attack its hardened cement paste and thus destroy the concrete as a whole. The high-performance concrete has excellent corrosion-resistant capability because it is a concrete of high compactness prepared with high-efficient water-reducing agents and super fine admixtures and in a low water-cement ratio

关 键 词：侵蚀 硫酸盐 高性能混凝土 抗侵蚀性
