19世纪,在北美洲含有硫酸盐的碱性土壤地区,曾发现在地下水道、涵洞、基础等处的混凝土被破坏。1892年米却利斯(W.Michaelis)研究指出,普通混凝土中有铝酸盐,与外界的硫酸盐和水接触,便化合成有害的“水泥杆菌”(即硫铝酸钙),其体积膨胀2.5倍,是混凝土破坏的原因。1936年法国洛西叶把产生“水泥杆菌”的成分,预先配入水泥中,发明了一种以无水硫铝酸钙熟料为膨胀组份的膨胀水 In the 19th century, in the alkaline soils containing sulfate in North America, it was found that the concrete in the underground watercourses, culverts, foundations, etc. was destroyed. In 1892, W.Michaelis pointed out that there are aluminates in ordinary concrete, and when it comes into contact with external sulfates and water, it can synthesize harmful “Melcobacteriosis” (ie, calcium sulfoaluminate). Its volume expansion of 2.5 times is the cause of concrete damage. In 1936, Losi Leaf of France produced the composition of “Melcobacteriosis,” which was pre-mixed into cement, and invented a kind of expansion water with calcium sulphoaluminate clinker as the expansion component.
