Cov khoom tseem ceeb tshaj plaws ntawm cov pob zeb tom qab hardening yog lub peev xwm ntawm cov pob zeb los tiv thaiv kev ntxhov siab xws li siab, nro, khoov thiab shear. Qhov sib piv ntawm cov dej-cement, hom thiab tus nqi ntawm cov cement, hom thiab cov nyiaj sib sau ua ke, nrog rau kev sib xyaw, sib sau thiab kho, txhua yam cuam tshuam ncaj qha rau lub zog ntawm pob zeb. Qhob raws li tus qauv compressive zog (nrog rau lub voos xwmfab nrog ib sab ntev ntawm 150mm raws li tus qauv qauv, kho rau 28 hnub raws li tus qauv kho, raws li tus qauv xeem txoj kev nrog 95% lav tus nqi ntawm lub voos xwmfab compressive zog) faib los ntawm lub zog qib, hu ua daim ntawv lo, Nws muab faib ua 19 qib: C10, C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75, C80, C85, C90, C95 thiab C100. Lub zog tensile ntawm pob zeb tsuas yog 1/10 ~ 1/20 ntawm nws lub zog compressive. Txhim kho qhov piv ntawm tensile thiab compressive zog ntawm pob zeb yog ib qho tseem ceeb ntawm kev hloov kho pob zeb.
