Kev sib koom nrog kev sib xyaw uas tsis muaj cov pob zeb tawg tau tso cai rau koj kom txuag tau tom kawg. Tab sis cov pob zeb zoo li no yuav xav tau ntim av ntau dua ntawm cov xuab zeb thiab cov cement, yog li txuag ntawm qhov muaj pes tsawg leeg tsis tas yuav tawm los ua qhov ntxiv.

Qhov zoo thiab qhov tsis zoo

Cov pob zeb uas tsis tau tsoo pob zeb muaj lwm feem piv rau qhov loj me ntawm cov pob zeb tawg (piv txwv li, nthuav av nplaum). Hauv qhov yooj yim tshaj plaws, qhov no yog cov cement-sand mortar, uas tsis muaj dab tsi ntxiv tshwj tsis yog dej. Qee cov tshuaj ntxiv tau ntxiv rau cov pob zeb niaj hnub uas ua lub luag haujlwm ntawm qhov tsis ua haujlwm uas ua rau nws ua haujlwm tsis tau zoo . Qhov zoo ntawm cov pob zeb uas tsis muaj pob zeb tsoo suav nrog kev pheej yig thiab muaj, yooj yim ntawm kev npaj thiab siv, ua haujlwm ntev, tiv taus qhov kub hloov pauv ntau txog kaum degrees hauv ib hnub.

Qhov tsis zoo yog tias lub zog ntawm cov pob zeb tsis muaj pob zeb tsoo yog qhov ua tsis tau zoo dua rau cov pob zeb ua ke uas muaj tag nrho cov pob zeb lossis pob zeb tsoo

Ib qho ntxiv, cov pob zeb npaj tau yuav los ntawm txhua yam ntawm cov neeg xa khoom yog tus nqi ntau dua li cov khoom tsim los ntawm txhais tes los ntawm cov khoom siv yuav ntawm nws tus kheej.

Feem pua

Kev faib ua feem ntau ntawm cov xuab zeb thiab cov cement yog 1: 2. Yog li ntawd, tau tsim cov pob zeb uas muaj zog zoo, haum rau ob lub hauv paus ntawm ib lub tsev hauv tsev, thiab rau screed, txhim kho thiab kho kom zoo nkauj phab ntsa.

Rau kev tsim cov xuab zeb ua vaj tsev, dej hiav txwv loj thiab nplua-nplua av dej xuab zeb yuav haum . Koj yuav tsum tsis txhob hloov cov xuab zeb nrog cov khoom sib xws zoo sib xws, piv txwv li, tawg ua npuas ncauj thaiv, pob zeb ci, hmoov zeb thiab lwm yam khoom siv zoo sib xws. Thiab yog tias koj sim npaj cov tshuaj khib nyiab uas tsis siv cov xuab zeb, tom qab ua kom tawv, qhov sib xyaw ua ke yuav yooj yim tawg. Cov khoom xyaw no raug tso cai tsuas yog hauv qhov me me - tsis pub ntau tshaj li ob peb feem pua ntawm tag nrho qhov hnyav thiab ntim ntawm cov khoom tau npaj, txwv tsis pub lub zog ntawm cov pob zeb yuav raug kev txom nyem ntau.

Ntawm tag nrho cov zaub mov txawv rau ua cov pob zeb qub muaj niaj hnub no, pob zeb raug tshem tawm. Cov kev xaiv no suav nrog kev suav, tsom mus rau 1 cubic meter ntawm cov pa (nrog pob zeb) qhob cug. Txhawm rau ua kom cov pob zeb haum haum tsis muaj pob zeb tawg, siv cov piv txwv tshwj xeeb hauv qab no.

1. " Portland MAAs-400 " - 492 hli Dej - 205 litres. PGO (PGS) - 661 kg. Cov pob zeb tsoo nrog qhov ntim ntawm 1 tuj tsis tau ntim.
2. " Portlandcement-300 " - 384 kg, 205 liv dej, PGO - 698 kg. 1055 kg ntawm pob zeb tawg - tsis siv.
3. " Portlandcement-200 " - 287 kg, 185 l dej, 751 kg ntawm PGO. 1135 kg ntawm pob zeb tawg tau ploj lawm.
4. " Portlandcement-100 " - 206 kg, 185 l dej, 780 kg ntawm PGO. Peb tsis ntim 1187 kg ntawm pob zeb.

Lub pob zeb ua tiav yuav siv ntau dua li ib lub 'meter', vim tias tsis muaj pob zeb tsoo hauv nws. Qib qib ntawm cov cement ntau dua los ntawm tus lej, qhov hnyav dua qhov ua rau cov qhob tau tsim los rau. Yog li, M-200 yog siv rau cov tsev tsis muaj peev txheej, thiab M-400 cement yog siv rau ib-zaj dab neeg thiab kev tsim kho hauv nroog qis. Maas M-500 tsim nyog rau lub hauv paus thiab thav duab ntawm ntau lub tsev tsev.

Vim yog qhov nce ntawm cov cement nyob rau hauv cov nqe lus ntawm qhov ntsuas kub tiag tiag ntawm cov pob zeb tau npaj raws li ib qho ntawm cov lus qhia saum toj no - cov txiaj ntsig tau tshwm sim muaj zog dua. Nws yog qhov zoo tshaj plaws rau kev siv cov pob zeb txhawb nqa, uas tsis muaj pob zeb tawg tag. Los ntawm qhov muaj pes tsawg leeg hloov pauv nyob rau hauv txoj kev no, cov pob zeb ua tiav tau ua, uas yog siv rau kev tsim kho cov tsev siab.

Kev sib xyaw me me ntawm gypsum lossis alabaster raug tso cai. Ua haujlwm nrog cov pob zeb zoo li no tau nrawm dua - nws nyuaj hauv tsuas yog ib nrab teev. Ib qho xuab zeb-xis mas zoo tib yam, npaj los ntawm txhais tes, teeb tsa hauv li 2 teev.

Qee tus neeg tsim khoom sib tov me ntsis xab npum nrog cov dej ntxiv rau hauv cov pob zeb, uas tso cai ua haujlwm txuas ntxiv mus txog 3 teev kom txog thaum cov khoom sib xyaw pib teeb tsa.

Raws li rau cov dej ntxiv, nws yuav tsum tsis pub dawb ntawm qhov tsis huv - piv txwv li, tsis muaj cov kua qaub thiab alkaline reagents. Cov organic seem (cov ntoo, cov ntoo ntoo) yuav coj cov pob zeb ua kom tawg sai dua.

Sawdust thiab av nplaum ntxiv rau pob zeb kuj txo nws cov yam ntxwv lub zog . Nws raug nquahu kom siv cov xuab zeb ntxuav, hauv qhov xwm txheej hnyav - cog. Cov cement yuav tsum yog qhov tshiab raws li ua tau, tsis muaj cov pob thiab cov pob zeb: yog tias muaj, tom qab ntawd lawv raug pov tseg. Qhov xav tau ntawm cov khoom xyaw yog ntsuas nrog tib lub ntim, hais tias, lub thoob. Yog tias peb tab tom tham txog qhov me me - piv txwv li, rau kev kho kom zoo nkauj - tom qab ntawd tsom iav tau siv.

Nws siv qhov twg?

Ntxiv nrog rau lub hauv paus thiab hauv av screed, pob zeb tsis muaj pob zeb tawg yog siv rau nchuav ntaiv. Siv cov pob zeb ua kom tsis muaj pob zeb tawg (pob zeb txhawb nqa), pov rau hauv daim ntawv ntawm lub dav hlau ntawm cov ntaiv, muaj tshwj xeeb tshaj yog cov nplua nuj (dej) xuab zeb, hauv ib feem - qhov kev tshuaj xyuas tsawg tshaj plaws ntawm cov xuab zeb dej. Piv txwv li, coarser xuab zeb, tshuaj xyuas cov xuab zeb hauv hiav txwv, tau pom daim ntawv thov rau kev tsim cov paving slabs . Ntau cov cement zoo li cov pob zeb muaj, muaj zog dua paving slabs ua los ntawm nws. Tab sis qhov no tsis txhais tau tias cov cement yuav tsum tau sib xyaw hauv qhov sib piv ntau dua 1: 1 (tsis yog qhov zoo ntawm qhov feem pua ntawm cov xuab zeb) - qhov no, cov nplais yuav tau txais qhov tsis muaj qhov tsis txaus kiag li rau nws. Cov ntsiab lus siab dua ntawm cov cement tso cai kom tau cov vuas tsim rau txoj hauv kev, cov ntsiab lus qis dua rau cov neeg taug kev thiab chaw ua si.

Nws tsis pom zoo kom nchuav cov pob zeb ua ke nrog qhov ua rau tsis zoo tshaj li 1: 3 (hauv qhov nyiam ntawm cov xuab zeb). Xws li kev sib xyaw hu ua "lean concrete", uas tsim nyog rau kev kho kom zoo nkauj phab ntsa.
