1. Hloov qhov kub thiab txias
Qhov kub hloov pauv yog qhov laj thawj tseem ceeb ntawmcement batching cogpob zeb tawg. Nyob rau hauv kev sib koom ua ke ntawm sab nraud ambient kub thiab sab hauv hydrothermal nyhuv, pob zeb yog heev nquag rau pob zeb tawg. Yog tias cov cua sov sab hauv ntawm cov pob zeb tsis tuaj yeem tso tawm tau zoo, nws yuav nthuav dav vim qhov kub thiab txias, ua rau muaj kev ntxhov siab tensile thiab rhuav tshem qhov ruaj khov ntawm cov qauv qub; Cov kab nrib pleb yuav tshwm rau sab hauv lossis ntawm qhov chaw, uas yog, qhov kub thiab txias.
2. Deformation
Yog hais tias lub deformation raug txwv thiab lub zog tensile ntawm lub pob zeb yog tsawg dua qhov kev ntxhov siab ntawm nws cov qauv sab hauv, tawg yuav tshwm sim. Tsis tas li ntawd, pob zeb tseem yuav tsim cov pob zeb tawg, uas feem ntau suav nrog ob hom. Ib qho yog qhov deformation tshwm sim los ntawm tus kheej hnyav hnyav ntawm cov pob zeb ua qauv, uas txhawb kev tawg; Lwm qhov yog los ntshav ntxov ntxov ntawm pob zeb thiab tsis muaj dej noo hauv cov pob zeb. tawg.
3. Kev poob qis
Ntau qhov tseeb qhia tau hais tias qhov shrinkage ntawm pob zeb yuav ua rau tawg ntawm nws cov qauv. Qhov laj thawj tseem ceeb rau hom kev tawg no yog tias cov pob zeb tsis tau ua haujlwm tau zoo tom qab hardening thiab sib sau, ua rau cov dej ntog sai heev, ua rau muaj qhov tshwm sim loj heev.
4. Lub hauv paus tsis sib haum
Kev tsis sib haum xeeb ntawm lub hauv paus kuj tseem yog qhov ua rau pob zeb tawg. Cov kab nrib pleb tshwm sim los ntawm qhov tsis sib haum xeeb ntawm lub hauv paus yuav loj dua vim qhov chaw sib txawv ntawm qhov kev sib haum xeeb nce.
