PC磚告訴你水泥凝固要多長時(shí)間

水泥是粉狀水硬性無機(jī)膠凝材料。加水?dāng)嚢韬蟪蓾{體，能在空氣中硬化或者在水中更好的硬化，并能把砂、石等材料牢固地膠結(jié)在一起。根據(jù)水泥熟料配料方案和煅燒狀況不同，以及摻加混合材種類和含量不同，加之不同區(qū)域?qū)λ噘|(zhì)量要求指標(biāo)不同，水泥的凝結(jié)時(shí)間也不相同。

一般地，42.5強(qiáng)度等級的水泥要比32.5等級水泥凝結(jié)時(shí)間短。帶R的與不帶R的要短，短約10~30分鐘。

要根據(jù)溫度確定：在20度時(shí)，5－8小時(shí)時(shí)，水泥砂漿會達(dá)到終凝。這時(shí)用手指已經(jīng)按不動。再過20分鐘灑水最好。
