Cov npuas npuas, koom nrog hauv chav kawm ntawm cov pob zeb ntxeem tau, yog cov khoom siv zoo heev rau kev tsim lub tsev zoo thiab pheej yig. Thov nco ntsoov tias nyob rau hauv ntau yam ntawm nws cov khoom, ua npuas ncauj ua npuas ncauj yog ntau zaus superior rau cib ib txwm siv nyob rau hauv kev tsim kho. Kev nrawm ntawm kev tsim lub tsev los ntawm cov khoom siv no tsuas yog amazing. Qhov no feem ntau yog vim qhov tseeb tias qhov loj ntawm txawm tias qhov tsawg tshaj plaws thaiv yog ntau zaus ntau dua li qhov loj ntawm tus qauv cib. Hauv ib lo lus, ua npuas ncauj blocks (kev tshuaj xyuas uas hais rau lawv tus kheej) yog cov khoom siv zoo heev rau kev tsim kho.
Muab lub teeb ci ntawm cov khoom siv hauv tsev, ib pab pawg me ntawm cov neeg tsim tuaj yeem ua haujlwm. Nws yuav tsum tau muab sau tseg tias ib tug feature ntawm lub npuas block yog zoo heev thermal rwb thaiv tsev, ua ke nrog tsis muaj tsawg zoo hygroscopicity. Qhov tseeb no yuam kev siv lub siab tshaj plaws waterproofing. Vim yog qhov xwm txheej zoo ib yam, nws yog ib qho tsim nyog yuav tsum ua tib zoo saib xyuas kev tsim kho tshuab ntawm lub tsev. Txwv tsis pub, ua npuas ncauj thaiv phab ntsa yuav tsis kav ntev.
Txuag ntauNws muaj peev xwm yog tias koj tus kheej nqa cov khoom siv hauv tsev los ntawm cov chaw tsim khoom rau koj qhov chaw tsim kho. Nws yog ib qho tseem ceeb heev kom paub tseeb tias lub ntim yas uas tiv thaiv cov chav nyob los ntawm huab cua ntub yog nyob rau hauv zoo meej. Txawm hais tias kev tsim ua npuas ncauj tau tab tom ua, cov khoom siv yuav tsum muab khaws cia tshwj xeeb hauv qab los.
Kev tsim vaj tsev feem ntau xyaum tsis txawv ntawm ib qho twg. Qhov nyuaj yog tias nws tsis yog ib txwm paub meej tias lub hauv paus twg los xaiv. Yog lawm, cov blocks lawv tus kheej tsis hnyav dhau, tab sis yog tias lawv ua tsis tau zoo, lawv yuav inevitably pib nqus dej noo, uas yuav ua rau muaj qhov hnyav ntawm tag nrho lub tsev. Tias yog vim li cas nws yog qhov zoo dua los siv cov qauv sawb hauv paus, vim tias lawv muaj ntau yam thiab tuaj yeem tiv taus qhov vibrations ntawm lub tsev tiav. Txawm li cas los xij, feem ntau ua npuas ncauj blocks (kev tshuaj xyuas ntawm cov neeg tsim khoom hais txog qhov zoo) yog qhov ruaj khov, lawv xyaum tsis raug rau thermal expansion.
Qhov kom zoo dua ntawm lub hauv paus sawb kuj yog tias nyob rau hauv cov tsev zoo li no tuaj yeem ua rau hauv qab daus. Lub hauv paus yog tsim los ntawm tib lub npuas npuas. Yog li ntawd, nws yog ib qho ua tau tsis tsuas yog ua kom ceev cov txheej txheem kev tsim kho, tab sis kuj yuav tsum tau tshem ntawm qhov xav tau ntxiv rwb thaiv tsev ntawm lub hauv paus. Ntawm chav kawm, koj yuav tsum ua tib zoo xyuas cov theem ntawm lub hauv paus ua ntej pib kev tsim kho, vim tias qhov tsis zoo nyob rau yav tom ntej yuav nyuaj dua los kho. Thaum cov npuas blocks (kev tshuaj xyuas uas paub tseeb tias qhov tseeb) tau muab tso ua ke, nws yog qhov tsis xav ua haujlwm nrog lawv vim lawv qhov tsis yooj yim.
Nws raug nquahu kom ua cov masonry nws tus kheej hauv cov tsev no tsis yog ntawm tus qauv cement mortar, tab sis ntawm cov kua nplaum tshwj xeeb, uas txhim kho cov yam ntxwv ntawm lub tsev ntau zaus. Cov kua nplaum zoo li no yooj yim heev rau siv: nws yog diluted nrog tus nqi ntawm cov dej qhia hauv cov lus qhia thiab sib tov kom huv si kom txog thaum sib tov homogeneous. Nws yog ib qho tseem ceeb los mus tas li thiab nruj me ntsis tswj qhov zoo tshaj plaws kab rov tav txoj hauj lwm ntawm masonry, txij li thaum lub pob zeb ua npuas ncauj yog heev rhiab heev rau txawm lub slightest distortions thiab reacts heev heev mob rau lawv. Tau kawg, tus nqi ntawm cov kua nplaum me ntsis nce tus nqi ntawm tag nrho kev tsim kho, tab sis lub neej kev pab cuam ntawm lub tsev yuav ntev dua. Tsis tas li ntawd, nws tsim kev tiv thaiv ntxiv nyob rau hauv txoj kev ntawm noo noo, uas yog undesirable rau cov khoom no: ua npuas ncauj blocks (xyuas uas ceeb toom ntawm xws li ib tug tshwm sim) zoo kawg nkaus nqus nws, thiab raug puas tsuaj nyob rau hauv lub qis kub.
