摘要
硫酸盐侵蚀直接影响建筑结构的耐久性,不同侵蚀环境下硫酸盐侵蚀类型和机理不同。根据硫酸盐侵蚀介质种类、侵蚀机理,按照腐蚀产物稳定存在的碱性条件将水泥基材料硫酸盐侵蚀划分为5种类型:钙矾石型、石膏型、镁硫型、碳硫硅酸钙型和盐类析晶型。阐述了5种典型硫酸盐的侵蚀环境、侵蚀机理和存在的异议。
Sulfate attack of concrete and mortar has influence on durability of construction directly. Form and mechanism of sulfate attack differ from corrosion circumstance. Form of sulfate attack of concretes and mortars has been divided into 5 sats of form according to corrosion circumstance and mechanism of deterioration, including ettringite form, gypsum form, magnesium form,thaumasite form and salt crystallization form of sulfate attack. Some controversy sulfate attack mechanisms have been presented in the paper.
