spray concrete 中文意思是什麼
spray concrete
解釋
噴射混凝土-
Shotcrete - rock bolt support and concrete lining are important parts of timbering structures in modern tunnel construction, and there are also essentials for natm. the intensity difference of concrete is big because of the big randomicity at the aspects of material, metage of additive, mix round, ratio of water and lime, spray construct and water maintain
由於噴射混凝土和二次襯砌在拌和料、外加速凝劑的稱量、拌勻以及水灰比的配比、在噴射作業及灑水養護上都存在著很大的隨機性，其強度的差異也較大。 -
