Grey CSA Cement Qib 42.5 yog cov calcium sulfoaluminate cement uas tawv sai sai uas tsim los rau cov ntawv thov uas xav tau lub zog thaum ntxov thiab teeb tsa sai. Nws ua tiav25–30 MPa hauv 4 teevthiab42.5–50 MPa ntawm 28 hnub. Nrog rau qhov tsis tshua muaj zog shrinkage, zoo heev sulfate tsis kam, thiab ruaj khov ntawm qhov kub qis, nws yog qhov zoo tagnrho rau kev ua cov hauv qab uas nws tus kheej leveling, kho sai mortars, precast concrete, grouting, thiab kev tsim kho lub caij ntuj no. Cov grey CSA cement no muaj cov kev daws teeb meem zoo thiab pheej yig rau cov haujlwm tsim kho vaj tse thiab kev tsim kho. Muaj rau kev muab ntau lossis cov hnab.
