1.CLSM應該要先材料送審
承包商應提供生產廠商資料及使用配比表,且應有試拌結果之
試驗合格報告,檢附切結書保證CLSM不含回脹性粒料。
不要以為預拌就可以了,如果沒有事先送審,同樣不能用,不
能送A混凝土預拌廠的配比來審,結果用B混凝土預拌廠的料。
承商自行在現場拌合有配比嗎?有送審嗎?
2.真要在工地拌合,也沒不行,但同樣要先送審....
使用工地型拌和設備產製CLSM時,其拌和設備須事先提送計畫,
經工程司認可後方得使用。
你的承商現場拌合CLSM有經過你們的同意嗎?
3.CLSM一般一組3顆,都做28天的抗壓強度,七天也可以做,但
是抽測較多。
4.除設計時另有規定外,CLSM規定抗壓強度為28天齡期之試驗強度。
所以,七天那顆,一般是參考用的....
5.CLSM不合格時,可以減價收受或刨除重做....送101是誇張一點...
除非承商完全不配合,不按契約規範施作。
以上參考高雄市工務局之施工規範第3377章....當然,真要準,要看
你們自己的合約規範或圖說有沒有規定....
PS:如同有位版友提到,CLSM理論上是為了取代級配回填、又不用夯
實做工地密度,但也不能強度太強,免得以後無法開挖,要用破
碎機。
但個人經驗,台電埋管時,回填就是灌CLSM,結果後來路面還是
下陷,AC路面變成U型....
而聽說(只是聽說),台水埋管,回填灌的CLSM,會導致膨脹,AC
路面隆起。
