在炉窑和建筑工程中使用矾土水泥施工时湿工艺极为重要,笔者将其称为“三湿”工艺,即湿基层、湿拌合、湿养护。在这一点上,人们往往只注意到拌合时的水量,而忽略了基层吸收的水量和初硬后继续需要的水量。特别在炉窑修复中,耐火砖基层和拌合耐火混凝土粗细骨料容易吸 The use of alumina cement in kiln and construction projects is extremely important during wet construction. I call this the “three wet” process, ie, wet ground, wet mixing, and wet curing. At this point, people often only notice the amount of water when mixing, and ignore the amount of water absorbed by the grassroots and the amount of water that will continue to be needed after the initial hardening. Especially in the kiln repair, the coarse and fine aggregate of refractory brick base and mixing refractory concrete is easy to absorb
