Kev kuaj pom ntau
Kev xeem Cement: Portland cement, Portland cement zoo tib yam, slag silicate cement, volcanic tshauv silicate cement, ya tshauv silicate cement, composite silicate cement, G- qib roj zoo cement, txoj kev silicate cement, ceev hardening silicate cement, low heat slag silicate cement, expanded sulfoaluminate cement, phosphosphoric cement
Kev kuaj cov khoom siv cement: cement manhole npog, cement self leveling, cement cib, cement boards, cement mortar, cement pipes, thiab lwm yam.
Cov khoom kuaj
Specific gravity thiab bulk density:Lub ntiajteb txawj nqus ntawm cov cement zoo tib yam yog 3: 1, thiab qhov ntom ntom feem ntau yog 1300kg / m3.
Fineness: hais txog lub thickness ntawm cov cement hais. Qhov zoo dua cov khoom, qhov nrawm dua qhov hardening, thiab siab dua lub zog thaum ntxov.
Teem sijhawm:Lub sij hawm xav tau rau kev sib xyaw cement kom pib teeb tsa yog hu ua lub sijhawm pib. Lub sij hawm xav tau los ntawm kev ntxiv dej kom tiav solidification yog hu ua lub sij hawm kawg solidification. Lub sijhawm pib ntawm Portland cement tsis ntxov dua 45 feeb, thiab lub sijhawm teem sijhawm kawg tsis pub dhau 12 teev.
Lub zog: Lub zog ntawm cov cement yuav tsum ua raws li cov qauv hauv tebchaws.
Volume stability:hais txog kev ua tau zoo ntawm cov cement ntim hloov thaum lub sij hawm hardening txheej txheem. Cov cement muaj ntau cov impurities, uas tuaj yeem ua rau deformation tsis sib xws.
Hydration cua sov:Kev sib cuam tshuam ntawm cov cement thiab dej ua rau cov tshuaj tiv thaiv exothermic. Qhov kev tso tawm tas li ntawm cov cua sov thaum lub sij hawm hardening txheej txheem ntawm cement yog hu ua hydration heat.
Txheem viscosity:hais txog qhov viscosity ntawm cov cement slurry thaum muaj qee yam tsis kam rau lub tog dej ntawm tus qauv ntsuas pas nrig.
Tus naj npawb ntawm cov qauv rho tawm los ntawm txhua pawg yuav tsum tsis pub tsawg dua 16kg. Cov qauv yuav tsum muab faib ua ob qhov sib npaug, txhua qhov hnyav tsawg kawg yog 8 kg. Ib feem yuav tsum yog tus qauv kuaj, thiab lwm qhov yuav tsum yog tus qauv thaub qab.
