Hauv cov ntsiab lus no:
32 MPa pob zeb: Qhov no txhais tau tias cov pob zeb muaj lub zog compressive ntawm 32 megapascals, uas yog qhov ntsuas ntawm nws lub peev xwm los tiv thaiv compression. Nws raug suav hais tias yog qhov nruab nrab lub zog sib xyaw ua ke, haum rau ntau yam kev siv, nrog rau kev siv hauv vaj tse, pavements, thiab lwm yam kev tsim kho.
25 MPa pob zeb: Qhov no txhais tau hais tias cov pob zeb muaj lub zog compressive ntawm 25 megapascals, uas yog lub zog qis dua piv rau 32 MPa pob zeb. Thaum 25 MPa pob zeb tseem muaj zog thiab haum rau ntau daim ntawv thov, nws yuav tsis siv rau hauv cov khoom siv uas yuav tsum tau muaj zog dua.
Hauv cov ntsiab lus, thaum sib piv cov pob zeb ua kom muaj zog, qhov siab dua MPa qhia tias muaj zog ua vaj tse. Qhob nrog lub zog compressive ntawm 32 MPa yog qhov muaj zog tshaj li pob zeb nrog lub zog compressive ntawm 25 MPa. Qhov kev xaiv ntawm pob zeb muaj zog yog nyob ntawm qhov kev xav tau tshwj xeeb thiab lub peev xwm thauj khoom ntawm qhov kev tsim kho.
