Q: Kodi kugwiritsa ntchito jenereta nthunzi kuchiritsa pambuyo kuthira osakaniza anamaliza?

A: Pambuyo kutsanuliridwa konkire, slurry alibe mphamvu, ndipo kuuma kwa konkire kumadalira kuuma kwa simenti.Mwachitsanzo, nthawi yoyamba yoyika simenti ya Portland ndi mphindi 45, ndipo nthawi yomaliza yomaliza ndi maola 10, ndiko kuti, konkire imatsanuliridwa ndi kusungunuka ndikuyika pamenepo popanda kuisokoneza, ndipo imatha kuuma pang'onopang'ono pambuyo pa maola 10.Ngati mukufuna kuwonjezera kuchuluka kwa konkriti, muyenera kugwiritsa ntchito jenereta ya nthunzi pochiritsa nthunzi.Nthawi zambiri mumatha kuzindikira kuti konkire ikatsanulidwa, iyenera kuthiridwa ndi madzi.Izi zili choncho chifukwa simenti ndi hydraulic cementitious material, ndipo kuumitsa kwa simenti kumagwirizana ndi kutentha ndi chinyezi.Njira yopangira kutentha ndi kunyowa kwa konkire kuti ithandizire hydration ndi kuumitsa kwake kumatchedwa kuchiritsa.Zomwe zimafunikira kuti zisungidwe ndi kutentha ndi chinyezi.Pansi pa kutentha koyenera ndi mikhalidwe yoyenera, hydration ya simenti imatha kuyenda bwino ndikulimbikitsa kukula kwa mphamvu ya konkire.Kutentha kwa konkire kumakhudza kwambiri hydration ya simenti.Kutentha kwapamwamba, kuthamanga kwa hydration, ndipo mphamvu ya konkriti imakula mofulumira.Malo omwe konkire imathiridwa madzi ndi yonyowa, zomwe zimakhala zabwino kuti ziwumitsidwe.
