Dab tsi yog yam khoom zoo li pob zeb? Nws lub ntsiab Cheebtsam yog gravel los yog crushed pob zeb, uas nyob rau hauv lub resulting voids. Qhob yog siv nyob rau hauv ntau qhov chaw ntawm kev tsim kho. Raws li, xws li kev sib tov tuaj yeem siv rau kev xav tau sib txawv, uas txhais tau hais tias qhov ntim ntawm nws cov khoom sib txawv, tshwj xeeb yog cov cement, uas yog xam los ntawm kev noj ib 1 cubic meter ntawm pob zeb, uas thaum kawg cuam tshuam tus nqi ntawm cov khoom.
Qhob muaj nws qhov kev faib tawm thiab qib sib txawv. Lawv cov cim yog qhov qhia txog nws txoj kev ntseeg siab. Raws li, qhov ntau txhim khu kev qha cov khoom, qhov ntau kim nws yog. Tab sis kev siv cov pob zeb, nws cov qib sib txawv, feem ntau yog vim tsis muaj zog ntawm cov khoom siv, tab sis rau kev ua haujlwm ntawm cov khoom siv rau kev tsim kho, qhov sib tov no siv.
Qhob nws tus kheej nrog ntim ntawm 1 cubic meter muaj li ntawm 0.5 cubic meters ntawm xuab zeb, gravel thiab crushed pob zeb thiab cement. Kev noj cov cement ib lub voos xwmfab ntawm pob zeb yog txiav txim siab los ntawm nws cov hom. Cov uas nyiam tshaj yuav tau tham ntxiv.
"M100" - qhov hnyav ntawm cov cement yuav tsum yog 220 kg ib 1 cu. Nws yog siv nyob rau hauv monolithic qhob vaj tse, curbs, pem teb, concreted rau hauv av.
"M200" - cement noj ib lub voos xwmfab ntawm pob zeb - ntawm 280 kg. Cov yam ntxwv los ntawm lub zog tensile siab. Tsim nyog siv rau hauv lub hauv paus, lub hauv paus ntawm ntau yam qauv, thaum tsim ib co kev me me (piv txwv li, rau cov neeg taug kev).
"M250" - cov cement yuav tsum yog 330 kg. Cov hom no yog qhov xav tau qis, txawm hais tias nws cov yam ntxwv zoo dua li cov yav dhau los. Feem ntau siv nyob rau hauv lub hauv paus ntawm cov tsev monolithic, ntaiv, kev taug kev.
380 kg ntawm cement yog nchuav rau hauv "M300" pob zeb. Hom no yog siv rau hauv cov qauv tseem ceeb, uas yuav tsum yog qhov muaj zog tshaj plaws thiab muaj zog tshaj plaws, uas muaj kev nyab xeeb ntawm ntau tus neeg nyob ntawm. Ntawm qhov loj me me, cov pob zeb zoo li no tau siv tsis ntev los no hauv cheeb tsam Moscow. Yog tsis muaj cov khoom siv no, cov tshuab sau, kev tsim kho ntawm thaj chaw dig muag, cov phab ntsa monolithic thiab lem rau tsheb tsis tiav. Withstands kub txog li 180 degrees ua tsaug rau cov tshuaj additives ntxiv.
Ntxiv rau, rau txhua lub hauv paus, pob zeb yuav tsum tau ua hauv qhov sib piv ntawm 1: 3: 5. Hauv lwm lo lus, 1 thoob ntawm cement, 3 xuab zeb, thiab 5 gravel ntxiv. Dej tuaj yeem ntxiv los ntawm qhov muag. Cov proportions yuav tsum nyob twj ywm tib yam, qhov sib txawv tsuas yog nyob rau hauv hom cement nws tus kheej. Lub zog ntawm lub hauv paus tswj kev noj cov cement ib lub voos xwmfab ntawm pob zeb. Ua ntej koj yuav tsum xam qhov kev npaj siab ntawm cov qauv, thiab tom qab ntawd xaiv hom uas xav tau. Qhov tsawg kawg nkaus tso cai rau lub hauv paus yog M300, yog tias tus lej qis dua, ces nws yog txwv tsis pub siv cov khoom no rau kev tsim kho ntawm lub hauv paus.
Lub ntsiab lus xaus yog qhov kev ntseeg tau ntawm tag nrho lub tsev tsim qauv (lub tsev ntiag tug, lub tsev siab siab, tsev kawm ntawv, thiab lwm yam) ncaj qha nyob ntawm seb cov cement noj ib lub cube ntawm cov pob zeb yuav siv li cas. Qhov tseeb, muaj ntau ntau cov qhab nia, tsuas yog cov ntsiab lus tseem ceeb tshaj plaws tau nthuav tawm hauv qhov kev piav qhia no. Hom cement yog xaiv rau cov qauv tshwj xeeb, raws li cov qauv sau tseg.
