Txo kev ua haujlwm: Cov cement ntau dhau tuaj yeem ua rau cov mortar sib zog thiab tsis ua haujlwm. Nws dhau los ua nyuaj rau kev sib kis thiab siv, ua rau nws nyuaj rau kev sib koom ua ke masonry zoo.
Nce Shrinkage: mortar nrog ntau cov cement feem ntau ua rau qis dua thaum nws qhuav thiab kho. Qhov nce shrinkage no tuaj yeem ua rau tawg thiab qhov khoob hauv cov pob qij txha mortar.
Kev kub siab tshaj: Cement hydration generates cua sov, thiab cov cement ntau dhau tuaj yeem ua rau muaj cua sov ntau dhau. Qhov no tuaj yeem ua rau kev teeb tsa sai ntawm cov tshuaj khib nyiab, txo cov sijhawm ua haujlwm thiab ua rau nws nyuaj rau ua tiav cov haujlwm.
Txo Bond Strength: Txawm hais tias nws yuav zoo li counterintuitive, ntau cov cement tuaj yeem ua rau txo qis zog ntawm cov mortar thiab masonry units. Mortar nrog qhov tseeb proportions ntawm xuab zeb muab zoo adhesion.
Brittleness: mortar uas muaj ntau tshaj ntawm cov cement tuaj yeem ua nkig thiab ua rau tawg thaum muaj kev ntxhov siab, kev co, lossis kev txav mus los. Qhov no tuaj yeem ua rau cov qauv tsis muaj zog.
Cov khoom pov tseg: Ntxiv cov cement ntau dhau yog nkim, vim nws tuaj yeem kim. Nws kuj tseem tuaj yeem ua rau muaj kev sib koom ua ke ntau dua li qhov tsim nyog, uas tej zaum yuav tsis ua raws li cov qauv tsim lossis cov kev xav tau zoo nkauj.
Tsis zoo Durability: mortar nrog imbalanced proportions yuav tsis tiv ib puag ncig yam tseem ceeb los yog hnav thiab tsim kua muag raws li zoo raws li proportioned mortar. Tej zaum nws yuav raug kev puas tsuaj thiab deterioration dua nyob rau lub sij hawm.
Txhawm rau zam cov teeb meem no, nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov lus pom zoo sib xyaw ua ke rau cov khoom tshwj xeeb uas koj siv, raws li tau teev tseg los ntawm cov chaw tsim khoom lossis cov txheej txheem kev lag luam. Kev kho qhov sib xyaw tsim yuav tsum ua tib zoo thiab ua raws li qhov yuav tsum tau ua ntawm qhov project, suav nrog cov yam ntxwv xws li hom masonry, ib puag ncig, thiab kev xav txog cov qauv. Yog tias koj xav tau hloov kho cov tshuaj khib nyiab rau cov laj thawj tshwj xeeb, sab laj nrog tus kws tshaj lij kev tsim kho lossis tus kws tshaj lij los xyuas kom meej tias cov kev hloov kho yuav ua tau raws li cov qauv tsim nyog.
Peb Saner Heavy Industry (SEZG) tau tsim muaj nyob rau hauv 2010, Peb tshwj xeeb hauv kev tsim ntau yam khoom siv twj tso kua mis, nrog rau kev teeb tsa lub tshuab, lub zog mining machinery, ib puag ncig engineering machinery, thiab kev tshawb fawb thiab kev tsim cov kev daws teeb meem rau underground engineering machinery.
