Ya tshauv
Ya tshauv (tseem hu ua cov roj pulverized Tsim ntawm silica (sio₂: 40-60 (alumina (Fe₂₂₃: 5-15%: 5-15%) Tsis zoo li kev sib sau ua ke ib txwm muaj, ya tshauv muaj dual nqi: nws txo tons los ntawm cov av khib nyiab (piv txwv li, kev txo qis cov khoom siv).
Fly tshauv yog ntes los ntawm fais fab nroj tsuag flue gases ntawm electrostatic precipitators lossis cov hmoov av zoo (nruab nrab ntawm qhov loj me:
Pozzolanic kev ua:Reacts nrog xis mas calcium hydroxide (CA (Oh) los ua cov calcium -}} lub sij hawm ua kom muaj zog.
Micro - sua cov nyhuv:Ultra {{0} Cov ncuav zoo sau voids nruab nrab ntawm cov hmoov av.
Tus nqi efficiency:Hloov 15-30% ntawm cov cement hauv pob zeb sib xyaw, txiav cov khoom siv raw los ntawm 10-20% thaum txo cov roj carbon monissions (Maas ntau lawm nyiaj txiag rau 7% ntawm ntiaj teb bev).
Cov cwj pwm no ua rau ya tshauv lub pob kws ntawm "kev tsim kho ntsuab ntawm" kev tsim kho ntsuab, "sib thooj nrog leed, breeam, thiab lwm yam qauv kev ua kom ruaj khov.
