Kev tsim lub hauv paus ntawm lub tsev yog qhov nyuaj tshaj plaws ob qho tib si hauv cov khoom siv thiab hais txog kev siv zog ua haujlwm. Txhawm rau kom ntseeg tau thiab tsis siv nyiaj ntau dhau thiab siv dag zog, koj yuav tsum ua tib zoo xam cov nyiaj ntawm cov cement. Cov txheej txheem no nws muaj nws tus kheej qhov txawv, coj mus rau hauv tus account cov yam ntxwv ntawm cov av, cov yam ntxwv ntawm cov qauv txhawb nqa thiab ntau ntxiv.

Peculiarities

Thaum teeb tsa ib qhov haujlwm, koj yuav tsum tam sim nkag mus rau hauv nws qhov kwv yees ntawm kev siv tag nrho cov khoom siv hauv tsev, suav nrog cov hlua khi. Yuav thiab thauj txawm tias "tsuas yog" ntxiv 10 kg tuaj yeem kim heev; qhov tsis muaj ntawm lawv yuav cuam tshuam lub voj voog ntawm kev ua haujlwm zoo tshaj plaws, thiab qhov phem tshaj, yuav tsis tso cai rau lawv ua kom tiav. Lub luag haujlwm ntawm kev sau yog ib qho tseem ceeb heev: nws pab ua kom deformation ntxhov siab thiab zam kev sib hais haum ntawm cov tsev. Feem ntau, tshwj tsis yog muaj qhov laj thawj xav suav lwm yam, qhov sib piv nruab nrab ntawm cov khoom siv tshuaj khib (xuab zeb, xis mas thiab pob zeb) yog kwv yees li 3: 1: 5 (hauv feem).

Nws tau thov li cas?

Tsuas yog ua tib zoo xaiv cov pob zeb siv los tsim lub hauv paus ntawm lub tsev. Ua rau lawv xav tau qee yam txuj ci los ntawm cov neeg tsim khoom. Txhawm rau ua kom tiav cov sib xyaw kom muaj zog ntau li ntau tau, cov pob zeb tawg tau siv hauv daim ntawv ntawm cov feem ntawm 1-4 cm. Txhawm rau kom tau txais kev daws teeb meem hauv tsev, txhua qib qib ntawm cov chaw txua zeb zeb nrog cov qoob loj ntawm 0, 12-0, 35 cm tau siv.

Qhov concentration ntawm impurities hauv cov khoom siv inert no tsis tuaj yeem tshaj 5%.

Rau kev suav kom raug ntawm kev noj cov sib xyaw ua tiav cov cement, nws yog qhov tsim nyog yuav tsum coj mus rau hauv tus account lub npe ntawm cov ntawv tseem ceeb. M-100 raug suav tias yog qhov tsis txaus.

Cov khoom siv no yog npaj ua ntej rau:

• ntxhib pem teb screeds;
• plastering ua hauj lwm;
• nto tiav;
• tso tawm sab hauv.

Txij li lub peev xwm ntawm cov khoom siv, uas tuaj yeem pom twb tau nyob hauv thaj tsam ntawm nws daim ntawv thov, me me, los ntawm 1 cubic meter. m ntawm lub hauv paus ntawm lub tsev haus 220 kg ntawm phau ntawv tuav. M-200 lub npe tau lees paub tias yog cov plua plav thiab cov hmoov txheej, nws tsim nyog rau ntsej muag ua vaj tsev. Piv rau M-100, nws muaj zog dua, tab sis nws raug nqi me ntsis. Siv qib no ntawm cov cement tsuas yog qhov tsis muaj kev pheej hmoo ntawm dej nyab lossis kev nyuaj siab. Kev siv tshwj xeeb yog 280 kg.

Raws li cov kws tsim khoom, nws zoo dua los siv M-300 cov cement rau lub hauv paus . Nws yog nws tus uas tau tsim los rau txoj haujlwm zoo li no tau. Kev tiv thaiv tiv tauj nrog dej, sulfates, cov cua sov qis ua kom pom tseeb qhov no.

Raws li kev xyaum, peb tuaj yeem xav tias 1 cubic meter. m ntawm lub hauv paus, 380 kg ntawm phau ntawv qhuav yuav tsum tau siv.

M-400 yog qhov sib txawv ntxiv los ntawm kev tiv thaiv zoo rau kev sov siab ., pom zoo rau kev thauj mus los kev tsim kho thiab rau kev tsim kho cov qauv hauv av. Qhov tsis zoo tsuas yog tus nqi siab (thiab kev siv - 440 kg). M-500 sib txawv los ntawm M-400 hauv qhov ntsuas ntsuas ntawm kev ywj pheej thiab ua tau ntev ntawm pob zeb. Rau kev kawm ntawv 1 cubic meter. m twb tau siv raws nraim 0.5 tons ntawm cov khoom, lossis 10 hnab ntawm 50 kg.

Tseem ceeb: ntau yam pheej yig dua ntawm cov tshuaj khib hauv paus tuaj yeem txhim kho los ntawm kev qhia tshwj xeeb ntxiv.

Tab sis nws tseem zoo dua los txiav txim kom raug raws li qhov ua tau raws qhov yuav tsum tau ua ntawm nws, nrog rau kev siv tus nqi.

Nws tsis yog hom tshuaj uas txiav txim siab

Nws tsis yog txhua qhov tsim nyog los ua tus kws tshaj lij kws tshaj lij lossis tus thawj coj kom nkag siab tias tus nqi tsim nyog ntawm cov cement tau txiav txim siab tsis yog los ntawm qhov ua tau zoo ntawm cov phau ntawv uas tsim los ntawm tsob ntoo. Nws kuj tseem yuav tsum tau coj mus rau hauv tus account qhov tseeb tias lub sijhawm kawg ntawm kev ua kom tiav ntawm cov pob zeb hloov pauv los ntawm kev nce lossis txo qis hauv kev faib ua feem ntawm txhua feem ntawm kev sib xyaw. Cov thav duab feem ntau yog ua los ntawm cov cement ntawm M-300 pawg. Tab sis nws tsis pom zoo kom siv qib ntawm 600 txog 800: lawv tau npaj rau kev tsim kho tsuas yog cov txheej txheem muaj zog tshaj plaws, suav nrog cov tsev ntau lub tsev.

Dab tsi yog qhov tseem ceeb - rau kev tsim kho lub tsev me me, nws tsis pom zoo kom pib los ntawm kev suav ntawm cov lej hauv online: cov lej tau txais hauv txoj kev no tsis yog ib txwm muaj tseeb thiab muaj qhov yuam kev loj.

Nws yog qhov tseeb dua los xam qhov ntim ntawm kev tsim kho lub hauv paus uas yuav los tom ntej no siv cov qauv npaj ua:

• rau ib qho slab - thaj tsam sib npaug ntawm qhov siab;
• rau daim kab xev - sib npaug tag nrho qhov ntev ntawm cov qauv raug tsim thiab thaj tsam hla;
• rau cov pawg, ntu ntu ntawm ib qho kev txhawb nqa tau muab suav nrog tag nrho cov lej ntawm cov kev txhawb nqa.

Tseem ceeb: thaum npaj los daws qhov sib tov yam tsis muaj pob zeb tsoo, qhov sib piv ntawm cov dej thiab cov cement yuav tsum tau txo 10%. Tab sis tib lub sijhawm, peb yuav tsum tsis txhob hnov qab txog kev vam khom ntawm cov dej haus ntawm qhov ntim ntawm cov xuab zeb thiab qhov loj ntawm feem ntawm cov khoom siv pob zeb. Hauv qhov piv txwv ib txwm, uas tau muab hauv phau ntawv siv rau cov uas tsis yog cov kws tshwj xeeb, cov ntsiab lus tshwj xeeb no raug rho tawm. Tab sis kom tsis quav ntsej qhov xwm txheej no hauv kev tsim kho tiag tiag txhais tau tias yuav ntsib qhov tsis txaus siab heev.

Cia peb ua haujlwm:

• pob zeb tawg 2, 5 cm nrog ntom ntawm 2700 kg;
• xuab zeb nrog cov nplua nplua nrog ntom ntawm 2500 kg;
• Portland MAAs M-400 nrog ntom ntawm 3 tons.

Txhawm rau kom tau txais kev daws teeb meem ntawm pab pawg M-300 los ntawm cov khoom no, nws yuav tsum tau nkag mus rau qhov sib npaug ntawm 0.53. Rau 1 cubic meter. m. kev daws teeb meem yuav muaj 195 kg dej, lossis 0, 195 cubic meters. m. Qhov kev faib ua feem qhia tias 368 kg ntawm Portland cement yuav tsum raug xaiv. Paub txog qhov feem ntawm qhov tseem ceeb tshaj plaws qhuav, nws yog qhov yooj yim los suav qhov ntim ntim uas xav tau, lawv feem pua, thiab, yog li ntawd, tag nrho qhov hnyav.

Txawm hais tias qib siab dua ntawm cov cement tau siv ntau dua, nws yog qhov raug coj los siv, vim nws pab txhawb lub hauv paus rau qhov tsim nyog txwv.

Tswv yim & Tricks

Ib lo lus nug tshwm sim: "Puas yuav xaiv qhov kev daws teeb meem muaj zog txaus los tsim lub tsev?" Nws yog qhov zoo tshaj los sim nws qhov ua tau zoo hauv kev xyaum. Thaum tau npaj ib hom bar los ntawm kev suav sib xyaw, lawv tos nws kom khov thiab, siv rauj rau nruab nrab (nrog rau qhov hnyav ua haujlwm ntawm 0.5 kg), lawv sim tsav lub chisel nrog ib lub tshuab. Yog tias cov hniav ntawm cov cuab yeej kos ntau dua 0.5 cm, qhov no tsis zoo. Ib lub pob zeb dag, ntau dua lossis tsawg haum rau lub hauv paus, yuav tsum muab pov tawm ntawm cov txiab nrog qhov cuam tshuam.

Muaj lwm qhov sib txawv - lub nra uas tau ua los ntawm lub hauv paus los ntawm lub tsev, nws lub ru tsev, daus tau sau rau saum thiab txhua yam uas nyob hauv tsev. Los ntawm qhov tsis quav ntsej qhov ntsuas no, koj tsis tuaj yeem tsim lub hauv paus zoo. Yog li, 200 kg rau 1 sq. cm tau txiav txim siab yam tsawg kawg bar uas ib tus tuaj yeem tham yam tsawg kawg txog kev ntseeg tau. Qhov peev xwm ntawm cov pob zeb ua tiav tau tiav nrog kev tso tseeb ntawm cov cement mortar M-400 hauv qhov sib piv ntawm 1: 3: 5.

Koj tuaj yeem daws qhov teeb meem hauv txoj kev sib txawv me ntsis . Piv txwv tias koj xav sau rau hauv 1 sq. m nrog kev daws teeb meem ntawm 100 hli tuab. Qhov thaiv no tuaj yeem ua kom tiav nrog lub hnab txheem ntawm M-400 cov cement, tab sis yog tias koj siv M-300, koj yuav xav tau lwm 1 kg ntawm phau ntawv ntxiv. Raws li qhov tshwm sim, hauv ob qho tib si, tau muab pob zeb ntawm M-150 qeb, tsim nyog rau kev kho qhov tsis xws luag lossis khaws cov tsev thib ob. Lwm qhov tseeb tseem ceeb uas ib txwm muaj txiaj ntsig kom nco qab yog 1 lub voos xwmfab. m ntawm cov pob zeb ntawm pab pawg 300 tau txais los ntawm 600 kg ntawm cov cement ntawm qeb M-400.

Txhawm rau kom tsis txhob yuam kev nrog kev suav ntawm cov ntaub ntawv tsim nyog tsim nyog, nws tsim nyog tsom mus rau kev sib xyaw ua ke tau teev tseg hauv SNiP. Kev nruj ua raws li thev naus laus zis yuav pab tshem tawm kev poob siab vim yog koj li kev suav thiab cov kev daws teeb meem sib xyaw. Raws li nws, pob zeb yuav tsum sawv ntsug li 28 txog 30 hnub ntawm qhov kub txog 20 degrees. Ntxiv nrog rau qhov ua raws qhov tseeb ntawm qhov sib npaug, nws tsim nyog xav txog cov ntsuas no xws li cov dej noo, cov qoob loj ntawm cov cement: qee zaum lawv tsis muaj qhov cuam tshuam tsawg ntawm qhov tshwm sim ntawm kev tsim kho ua haujlwm dua li kev suav nruj ntawm kev siv tag nrho ntawm cov khoom sib xyaw hauv sib tov.
