Hom M mortar yog lub zog siab tshaj plaws mortar (tsawg kawg 2500 psi) thiab tsuas yog yuav tsum tau siv qhov twg muaj zog compressive tseem ceeb.
Tsis tas li ntawd, dab tsi yog qhov muaj zog pob zeb lossis mortar?
Hauv paus pob zeb yog muaj zog dua thiab ruaj khov dua yog li nws tuaj yeem siv rau cov haujlwm ua haujlwm xws li teeb tsa ncej whereas mortar yog siv los ua tus neeg sawv cev rau cib, pob zeb, thiab lwm yam. Pob zeb yog sib tov dej, cement, xuab zeb ib yam li mortar.
Tom qab, lo lus nug yog, yog mortar muaj zog tshaj cib? " Mortar yuav tsum tsis txhob yuav muaj zog dua tus cib "yog qhov paub zoo tshaj plaws hauv lub ntiaj teb bricklaying. Nyob rau hauv cov ntsiab lus no, " muaj zog dua " tsis txhais hais tias nws lub peev xwm load-bearing, tab sis lub mortar cov hardness thiab permeability. Tsim kom muaj zog mortar , Portland cement yog siv ua ke nrog lwm cov ntaub ntawv txheem.
Tsis tas li ntawd, qhov txawv ntawm Hom S thiab N mortar mix yog dab tsi?
Hom S muaj 2 qhov chaw portland cement , 1 feem hydrated txiv qaub thiab 9 seem xuab zeb. Hom N tau piav raws li lub hom phiaj dav dav mortar mix thiab tuaj yeem siv rau hauv qib siab, sab nrauv thiab sab hauv load-bearing installations. Hom N yog ua los ntawm 1 feem portland cement , 1 feem txiv qaub thiab 6 seem xuab zeb.
Dab tsi ntawm mortar yog siv rau cov blocks?
CEMEX cov Hom N Masonry Cement, Hom S Masonry Cement thiab Hom M Masonry Cement yog tsim tshwj xeeb thiab tsim los tsim masonry mortar . Cov masonry mortar feem ntau siv hauv cib, pob zeb thaiv thiab pob zeb masonry siv; nws kuj yog siv los tsim pob zeb plaster.

Dab tsi yog qhov muaj zog thiab qaug zog acid piav nrog piv txwv?
Cov kua qaub muaj zog sib cais (sib cais) tag nrho hauv dej). Piv txwv li, HCl, cov kua qaub muaj zog yuav tawg mus rau H + thiab Cl-ions. Cov acids tsis muaj zog dissociate ib nrab hauv dej. Piv txwv li, HF, cov kua qaub tsis muaj zog, tsuas yog yuav muaj qee yam ntawm HF cov molecules sib cais thaum twg los tau
Dab tsi yog qhov qaug zog acid thiab muaj zog puag tsim?
Cov ntsev ntawm cov kua qaub tsis muaj zog thiab lub hauv paus muaj zog ua rau hydrolysis hauv dej los tsim OH-ions ntxiv. Txij li thaum acetic acid yog ib qho tsis muaj zog acid, nws tseem unionized nyob rau hauv kev daws thiab cov OH-ions ua rau cov tshuaj yooj yim los yog alkaline. Ib yam li ntawd, ntsev ntawm lub zog acid thiab tsis muaj zog hauv paus yog acidic nyob rau hauv aqueous tov
Txoj cai twg yog txhawm rau muab lub zog saib xyuas muaj zog ntxiv dag zog rau kev ua txhaum cai lij choj tiv thaiv kev ua phem thiab tiv thaiv kev lag luam nyiaj txiag?

Dab tsi yog qhov kawg ntawm lub zog rau yuav luag txhua yam kab mob tshwj tsis yog cov neeg nyob sib sib zog nqus hauv dej hiav txwv ze ntawm lub qhov cua sov?
Dab tsi yog qhov kawg ntawm lub zog rau yuav luag txhua yam kab mob tshwj tsis yog cov neeg nyob sib sib zog nqus hauv dej hiav txwv ze ntawm lub qhov cua sov? Qhov kawg qhov chaw yuav yog lub hnub
Vim li cas cov duab ntawm titration nkhaus txawv rau titration ntawm muaj zog acid vs muaj zog puag thiab qaug zog acid vs muaj zog puag?
Cov duab dav dav ntawm titration nkhaus yog tib yam, tab sis pH ntawm qhov sib npaug sib txawv. Hauv qhov tsis muaj zog acid-muaj zog titration, pH yog ntau dua 7 ntawm qhov sib npaug. Hauv qhov muaj zog acid-tsis muaj zog titration, pH tsawg dua 7 ntawm qhov sib npaug
