Thaum pib ua haujlwm, cov tswv tsev lub caij ntuj sov yuav tsum tau ua raws li cov lus uas lawv tsis tau hnov dua. Piv txwv li, ntau tus xav paub seb BSG pob zeb yog dab tsi. Kev txiav txim siab ntawm cov ntawv luv luv yog qhov yooj yim - cov no yog npaj txhij-rau-siv qhob sib tov.
Ntawd yog, pob zeb uas xa ncaj qha mus rau qhov chaw tsim kho hauv daim ntawv tiav. Hauv qhov no nws txawv ntawm BSS - qhuav qhob sib tov. Lawv tseem yuav tsum tau diluted nrog dej hauv ib qho kev faib ua feem kom tau txais cov khoom tsim nyog.
Dab tsi sawv cev
Thaum BSG pob zeb xav tau, qhov kev txiav txim siab ntawm qhov qhia tau tias nws yog qhov sib xyaw ua ke, cov neeg siv khoom xav tau hu rau cov chaw tsim khoom ncaj qha. Nyob rau hauv cov ntaub ntawv no, lub tuam txhab xa cov khoom sib tov siv cov pob zeb tov khoom tsheb. Qhov no yog cov txheej txheem uas muaj cov cuab yeej tsim nyog uas tso cai rau koj tswj cov kev daws teeb meem hauv ib lub xeev kom txog thaum nws tuaj txog ntawm qhov chaw.
Raws li qhov muaj pes tsawg leeg, BSG yog cov khoom xyaw classic - cement, xuab zeb, crushed pob zeb, dej. Cov proportions nyob ntawm seb yam ntxwv ntawm cov khoom kawg yuav tsum muaj.khoom. Tsis tas li hauv BSG tej zaum yuav muaj cov khoom siv tshwj xeeb los txhim kho kev ua haujlwm ntawm cov khoom siv.
Deciphering BSG pob zeb txhais tau hais tias qhov sib tov twb tau npaj lawm, thiab tus neeg siv khoom tsis tuaj yeem tswj cov txheej txheem ntawm nws cov khoom. Txawm li cas los xij, qhov no tsis tau txhais hais tias txhua yam yog tshuav rau lub caij nyoog. Tag nrho cov txheej txheem tsim khoom tseem tswj tau.
Lub tuam txhab siv daim ntawv qhia ua tau raws li qhov yuav tsum tau ua ntawm GOST rau cov khoom sib tov. Qhob yog tsim los ntawm cov ntaub ntawv zoo raw khoom, cov khoom xyaw raug coj mus rau hauv qhov proportions, uas tso cai rau koj kom tau txais kev sib xyaw nrog cov yam ntxwv uas xav tau, uas yog, nws cov viscosity yuav ua tau raws li cov qauv, thiab tom qab hardening cov sib tov yuav tig mus rau hauv monolith. uas tuaj yeem tiv taus txhua yam khoom thauj.
Key Benefits
BSG tau siv ntau yam, ob qho tib si rau kev tsim vaj tsev nyob thiab kev tsim kho kev lag luam. Tau kawg, muaj qee hom pob zeb uas muaj cov yam ntxwv tshwj xeeb thiab tsis tuaj yeem tsim los siv cov thev naus laus zis, tab sis feem ntau, BSG yog cov khoom siv dav dav.
Deciphering BSG pob zeb hloov mus rau ntev heev. Nws yog feem ntau hu ua npaj-mixed pob zeb. Lub ntsiab kom zoo dua yog siab zoo. Ntawm qhov chaw tsim kho, nws yuav luag tsis yooj yim sua kom ua tiav cov yam ntxwv zoo li no. Tom qab tag nrho, rau qhov no nws yog ib qho tsim nyog los xyuas kom meej qhov kev tiv thaiv ntawm tag nrho cov khoom xyaw thiab fillers los ntawm kev sib kis, kom tswj tau qhov kub thiab txias, kom ua tau raws li qhov yuav tsum tau ua raws li qhov ntau npaum li cas rau txhua cov khoom xyaw.
Tag nrho cov no yog cov haujlwm nyuaj heev. Tsis txhob hais tiaskoj yuav tsum xaiv cov khoom xyaw zoo tshaj plaws los ntawm qhov pib thiab sib tov rau hauv ib qho kev sib lawv liag.
Type of BSG
Ntau cov qauv siv los faib cov pob zeb sib xyaw ua ke. Lawv muab faib ua pawg nyob ntawm qhov sib sau siv, qhov ntom ntawm cov cement, cov qauv ntawm cov khoom, nrog rau nws lub zog.
Los ntawm qhov kev xav no, lawv paub qhov txawv:
- lub teeb yuag;
- pob zeb sib xyaw BSG hnyav pob zeb, thiab lawv yog ob qho tib si thiab hnyav ntxiv;
- precast qhob rau kev siv.
Kev xaiv ntawm ntau yam tshwj xeeb yog nyob ntawm seb cov haujlwm twg raug teeb tsa los ntawm tus tsim tawm.
Qib npaj sib xyaw ua ke
Tsis txhob cuam tshuam cov hom pob zeb thiab nws hom. Cov neeg tsim khoom, raws li txoj cai, qhia tag nrho cov cim hauv lawv cov catalogs lossis cov npe teev nqi. Ntawd yog, lawv sau tsis yog "BSG B15 pob zeb", qhov kev txiav txim siab uas tsuas yog ib qho qhia txog lub zog. Lawv tuaj yeem sau tau, piv txwv li, "paj rwb M350 V 25 P4 F200 W8", thiab ntawm no cov cim qhia xws li nws lub zog, te tiv thaiv, kev txav mus los thiab txawm tias dej permeability twb tau nthuav tawm.
Qhov no tsis yog kev tshaj tawm xov xwm. Muaj GOST, pob zeb sib xyaw BSG ntawm cov pob zeb hnyav B15, lub teeb lossis txawm tias lub hom phiaj tshwj xeeb yuav tsum tau cim tag nrho. Nyob rau tib lub sijhawm, M yog qib ntawm cov khoom, P yog nws txoj kev txav mus los, F yog te tiv taus, thiab W yog dej tsis kam. Tib lub sijhawm, B yog chav kawm thiab tsis zoo ib yam li hom.
Qhov saum toj no tuaj yeem pom nrog piv txwv. M200 lossis M350 tsuas yog qhov nruab nrab ntawm lub zog compressive (txawm tias siv xovxwm tshwj xeeb los txiav txim siab lawv).
Txoj kev xav, qhov sib xyaw cement ntau dua, cov pob zeb yuav muaj zog dua. Yog li ntawd, cov lej uas tau qhia tom qab tsab ntawv M hais tias muaj pes tsawg cement muaj nyob rau hauv pob zeb. Raws li, nws ntseeg tau tias qib M50-M100 yog cov pob zeb uas muaj cov cement tsawg. Tom qab ntawd tuaj qhov sib tov nrog qhov nruab nrab. Thaum kawg, hauv qib M500-M600 - cov ntsiab lus siab tshaj ntawm cov cement. Lawv lub zog siab dua, thiab tus nqi ib yam nkaus.
Class
Hauv daim ntawv yooj yim, peb tuaj yeem hais tias qib ntawm pob zeb yog nws qhov sib npaug nruab nrab compressive zog, qhia hauv kgm / sq.cm. Thiab cov chav kawm tau lav lub zog hauv megapascals.
Piv txwv li, ib qho kev xa tuaj rau hauv mail: "Concrete BSG V15 P3 NKSCH". Qhov no yuav txhais tau tias lub zog lav yog 15 MPa. Yog hais tias peb txhais mus rau hauv nruab nrab compressive zog, peb tau 153. Qhov ntawd yog, kwv yees li sib raug rau M150 lossis txawm M200 hom.
Ua ntej, pob zeb tsuas yog cim. Tam sim no tsuas yog cov chav kawm yuav tsum muaj kev cuam tshuam hauv cov kev cai, tab sis ntau tus neeg muag khoom txuas ntxiv qhia lub npe lossis sau ob qho tib si.
Frost resistance
Frost tsis kam ntawm pob zeb kuj yog qhov taw qhia tseem ceeb. Nws qhia txog cov voj voog ntawm kev khov thiab tom qab thawing uas ib hom khoom muaj peev xwm tiv taus yam tsis poob nws qhov kev ua tau zoo.thiab tsis deforming.
Qhov ntsuas no hauv lub cim yog qhia los ntawm tsab ntawv Latin F. Cov lej tom qab nws qhia tias muaj pes tsawg lub voj voog lub pob zeb yuav kav ntev.
Piv txwv li, F50 yog 50 cycles. Nws yog qhov xav tau los xav tias 50 xyoo txhais li cas, tab sis qhov no tsis yog li ntawd, tsuas yog cov voj voog lawv tus kheej raug coj mus rau hauv tus account. Yog li ntawd, qhov qhab nia siab dua, qhov zoo dua.
Rau thaj chaw uas muaj lub caij ntuj no hnyav, feem ntau pom zoo kom xaiv cov pob zeb uas muaj qhov taw qhia tsawg kawg F500 thiab siab dua.
Nyob zoo dej hiav txwv
Lub kav ntev ntawm cov khoom yog cuam tshuam tsis yog los ntawm nws cov Frost tsis kam, tab sis kuj los ntawm nws cov dej tsis kam. Qhov taw qhia yog qhov tseem ceeb tshwj xeeb rau cov pob zeb, uas yog siv rau kev npaj cov hauv paus thiab nchuav cov hauv paus hauv av. Nws yog txhais los ntawm tsab ntawv Latin W thiab qhia txog cov dej siab uas cov pob zeb yuav tuaj yeem tiv taus.
Cov neeg yuav cov khoom sib tov qhuav tsis muaj kev txaus siab rau qhov ntsuas no. Ntxiv mus, lawv tseem yuav tau npaj cov pob zeb ntawm qhov chaw.
Cov neeg yuav BSG B20 W20 pob zeb tsis xav tau daim ntawv qhia: cov khoom sib xyaw yog nqa los ua tiav, nws tsuas yog siv rau 2 teev kom nws tsis poob nws cov khoom.
Qhov sib txawv ntawm cov pob zeb siv
Thaum xaiv hom pob zeb, txawm tias npaj txhij los yog sib tov qhuav, ua raws li cov cai hauv qab no:
- M100 yog cov khoom siv uas siv tau ob qho tib si rau kev npaj lub hauv paus rau txoj kev nto, thiab kho cov curbs, thiab rau nteg lub substrate thaum lub hauv paus pob zeb yog poured.
- M150 kuj yog feem ntau siv los tsimnpaj txheej rau kev tsim kho ntawm monolithic foundations. Nws tuaj yeem yog lub hauv paus ywj pheej, tab sis tsuas yog rau cov tsev me me xwb. Nws kuj yog siv rau kev ua vaj hauv cheeb tsam.
- M200 yog qhov kev xaiv nrov dua, uas feem ntau siv rau hauv kev tsim kho ntawm lub hauv paus puv ntoob ntawm ntau hom - tsis yog daim kab xev xwb, tsim los rau cov khoom me me, tab sis kuj monolithic lossis pawg. Nws yog siv rau screeding qhov twg muaj siab loads nyob rau hauv pem teb. Nws kuj tseem tsim nyog nyob rau hauv kev tsim kho ntawm ramps thiab stairs. Nrov heev hauv kev tsim kho qis qis.
- M250 muaj qhov zoo sib xws, tab sis siv tsawg dua. Tab sis nws yog indispensable rau kev tsim kho ntawm monolithic foundations siab zog.
- M300 yog hom khoom siv hauv kev tsim kho rau ntau lub hom phiaj. Nws yog qhov tsim nyog rau kev tsim cov pob zeb ua vaj tse, npaj txhij ya ntawm cov ntaiv, nws yog siv rau kev tsim vaj tse pob zeb, thiab lwm yam.
- M350 - twb muaj zog dua. Xws li kev sib xyaw yog tsim nyog txawm tias cov slabs hauv pem teb uas tuaj yeem tiv taus qhov hnyav.
Cov qauv choj yog ua los ntawm qib M400 pob zeb. Raws li kev lag luam thiab pob zeb M500. Tab sis qhov no yog lub zog siab heev. Hauv kev tsim kho vaj tse, cov khoom siv tsis tshua muaj siv - feem ntau nws yog siv rau hauv kev tsim cov dams, kev tsim cov tsev txhab nyiaj vaults, thiab lwm yam.
