Noob hnav dawb yog lub ntuj granite nrog kev ntxhib los mos zoo nkauj thiab cov daus yooj yim. Sesame dawb granite yog tsuas yog siv rau kev ua yeeb yam dai rau sab hauv thiab sab nrauv phab ntsa ntawm qib siab tha xim sab hauv phab ntsa. Noob hnav dawb granite yog ib qho ntawm cov pob zeb granite nto moo tshaj plaws nyob hauv lub ntiaj teb. Nws txhua xyoo export ntim thiab muag khoom sab hauv yog qhov zoo. Nws tuaj yeem siv los ua cov vuas vov tsev, pua pua rooj, txee rau pem teb, txua ntoo, txua ntoo txaij sab nrauv, sab hauv phab ntsa, pem teb, square engineering panels, Environmental kho kom zoo nkauj ntawm cov pob zeb thiab lwm yam khoom siv rau kev tsim kho thiab pob zeb vaj.
Cov yam ntxwv ntawm sesame dawb granite: Granite tau nplua-nplua, nruab nrab-nplej, coarse-grained granular qauv, lossis plaque-zoo li tus qauv, nrog cov sib txawv thiab cov nplua zoo, qhov chaw qhib me me (porosity feem ntau yog 0.3% rau 0.7%), dej kev nqus tsis ua haujlwm siab (kev nqus dej yog feem ntau 0.15% ~ 0.46%), thiab muaj cov dej ua haujlwm zoo tiv thaiv.
Lub noob hnav dawb granite muaj qhov siab hardness, nws qhov Mohs hardness yog li 6, nws qhov ntom nruab nrab ntawm 2.63 g / cm3 thiab 2.75 g / cm3, nws cov kev ua kom muaj zog yog 100-300MPa, thiab cov nplua-nplua granite tuaj yeem siab txog 300MPa lossis ntau dua , thiab nws lub zog flexural Feem ntau, nws li ntawm 10 txog 30 MPa. Noob hnav dawb granite feem ntau tsim nyob rau hauv daim ntawv ntawm cov pob zeb, pob zeb pob zeb, thiab pob zeb pob zeb, thiab raug tswj los ntawm thaj chaw geodetic.
Cov phiaj xwm dav dav yog qhov loj thiab dav faib, yog li nws yooj yim mus khawb, yooj yim los tsim cov khoom loj, thiab nws cov pob qij txha tau tsim kho kom tsis tu ncua, uas yog qhov zoo rau kev tsuas ntawm cov pob zeb zoo li niaj zaus. Zoo heev spellability. Thiab sesame dawb granite tsis yooj yim rau huab cua, thiab tuaj yeem siv ua pob zeb dai kom zoo nkauj sab nraum zoov.
