High-lub zog pob zeb yog ib qho ntawm cov khoom siv niaj hnub tsim khoom. Nws txawv ntawm cov classic version nyob rau hauv kev ua hauj lwm zog thiab technical indicators.
Cov khoom uas muaj cov pob zeb muaj zog muaj zog ntau dua kev ntseeg siab dua li cov mortars. Cov qauv tsim los ntawm cov khoom siv no yuav ua tau zoo thiab ruaj khov.
Nce thiab kev faib tawm
hom kev ua vaj tse siab muaj xws li cov nplua-grained thiab hnyav hnyav uas muaj qib sib txawv. Cia peb xav txog txhua yam ntawm lawv kom ntxaws ntxiv.
M600, M700 thiab M750
Cov qib no ntawm cov pob zeb muaj zog muaj zog zoo thiab lub zog, nrog rau qib siab ntawm cov dej tsis kam. Cov pob zeb zoo li no yog siv rau hauv kev tsim cov ntaiv, txuas hniav, pas dej ua ke, hauv qab daus, ntau yam khoom siv thauj khoom.
M800
Nws tsis yog lub zog siab xwb, tab sis kuj tiv thaiv qhov chaw nruj heev. Yog vim li cas cov pob zeb no feem ntau siv thaum lub sij hawm tsim cov khoom nrog lub hom phiaj tshwj xeeb.
M900
Qhob ntawm hom no muaj qhov nce ntxivzog. Cov khoom siv zoo li no yog siv rau hauv cov cheeb tsam uas yuav tsum tau tsim tshwj xeeb tshaj yog txhim khu kev qha.
M1100
Nov yog lub hom phiaj tshwj xeeb. Nws yog qhov txawv tsis tau tsuas yog los ntawm nws lub zog siab heev, tab sis kuj los ntawm nws txoj kev tiv thaiv kom ya raws thiab qhov cuam tshuam ntawm kev ua phem ib puag ncig. Feem ntau, cov khoom siv ntawm qib no yog siv thaum siv hydraulic thiab tub rog cov chaw, txuas hniav, mines.
Raws li tus nqi qis kawg ntawm compressive zog, qhov no yog chav B60. Cov nqi saum toj no tso cai.
Ib yam ntawm cov pob zeb muaj zog yog tias lawv tawv sai sai. Vim li no, lawv cov yam ntxwv muaj zog nce.
Composition
Cov khoom uas yog ib feem ntawm lub tsev sib tov cuam tshuam rau cov khoom tshwm sim.
Cov khoom hauv qab no yog lub hauv paus:
- Txhob Cia Siab. Feem ntau lawv lub luag haujlwm yog ua los ntawm Portland cements feem ntau nrog rau qhov ntsuas qhov sib xws. Cov kws tshaj lij qhia siv cov khoom siv nrog qhov ntom ntawm 25%. Qhov taw qhia yam tsawg kawg nkaus yuav tsum yog kwv yees li 500-600. Txij li thaum cov pob zeb ua tiav tau txais lub zog ntawm qhov nrawm nrawm, nws tsis tas yuav siv ntau yam khoom ntxiv uas yuav ua kom qhov kev teeb tsa ntawm qhov muaj pes tsawg leeg.
- Sand. Kev tsim cov vaj tsev sib xyaw nrog lub zog siab tsis tuaj yeem nqa tawm yam tsis muaj kev siv feldspar-type quartz xuab zeb nrog cov nplua lossis ntxhib feem. Rau cov nplua-grained ntau yam, hais txog qhov loj ntawm 0.14 mus rau 0.63 mm yog haum, thiab rau coarse-grained ntau yam, los ntawm 1.25 mus rau 5 mm. Yuav kom lub tsev muaj pes tsawg leeg kom haum zoo dua thaum lub sij hawm nws daim ntawv thov, ntau ntawm cov thawj Cheebtsam yog siv. Qee zaum, qhov piv ntawm cov khoom loj thiab me me yog sib npaug. Hauv qee qib (txog M800), tsuas yog siv cov xuab zeb nruab nrab lossis ntxhib. Lub xeev cov qauv yeej ib txwm muab rau hauv tus account.
- loj muab tub lim. Nyob rau hauv xws li compositions, gravel plays lub luag hauj lwm zoo sib xws. Nws lub zog compressive ntawm cov av noo siab yuav tsum yog 1.5 npaug ntau dua li cov tshuaj. Ua ntej ntxiv xws li ib tug muab tub lim, nws yog sorted thiab ntxuav. Cov khoom yog muab faib ua feem ntawm 0.5-1 cm, 1-2 cm, thiab 2-4 cm. Cov hom crushed pob zeb yog xaiv nyob ntawm seb lub zog siv thiab cov phiaj dav dav ntawm cov khoom yav tom ntej. Yog tias cov qauv muaj qhov tsis muaj zog thiab cov phab ntsa tuab, ces cov khoom siv txog li 7 cm loj yog siv rau cov pob zeb uas muaj zog ntxiv, tsuas yog siv cov khoom sib xyaw qhuav uas ua tau raws li cov cai hauv GOST.
- Zoo additives. Silica-hom plua plav yog nchuav rau hauv cov pob zeb uas muaj zog ntxiv. Tab sis qhov no tsis yog ib txwm xyaum. Piv txwv li, yog tias qhov ntsuas lub zog yog C 55/67 lossis C 60/77, ces koj tsis tuaj yeem siv cov khoom siv ntxiv. Silica plua plav tau txais thaum lub sijhawm tsim khoom siv flint. Nws ua ntau yam haujlwm tseem ceeb. Ua ntej, nws nkag mus rau qhov chaw khoob ntawm cov khoom ntawm cov khoom tseem ceeb. Vim li no, qhov ntom ntawm cov khoom ua vaj tse nce. Thib ob, nws cuam tshuam nrog cov txiv qaub slaked, vim tias qhov ntsuas lub zog nce ntau dua. Thib peb, cov tshuaj tiv thaiv ntawm cov cement thiab xuab zebtau zoo dua thiab.
Ntxiv rau cov khoom teev tseg, cov khoom siv dag zog ntxiv tuaj yeem siv rau hauv cov pob zeb ntawm hom no.
Key Features
High-lub zog, nplua-grained concretes muaj ntau yam zoo, vim qhov kev pab cuam lub neej ntawm cov khoom tshwm sim nce.
Ib qho kev daws ntawm pob zeb hauv cov kua dej muaj cov yam ntxwv hauv qab no:
- Delamination tsawg tsawg.
- Tus nqi ntawm cov pa hauv qhov sib tov tsis ntau tshaj 1%.
- Qhov ntom ntawm cov qauv sib txawv ntawm 1-1, 4.
- Rheological zog khaws cia txog li 4 teev.
Ib qho tshwj xeeb ntawm cov pob zeb muaj zog yog tias nws khaws nws cov khoom ua haujlwm tau ntev. Qhov no yog qhov tseem ceeb, txij li cov khoom siv tuaj yeem thauj tau tsis pub dhau ob teev mus rau qhov chaw uas txhua txoj haujlwm tau ua. Tab sis qhov taw qhia ntawm qhov ntom ntawm qhov sib tov kuj cuam tshuam. Nws yuav tsum yog homogeneous, txwv tsis pub qhov tshwm sim ntawm nws delamination yav tom ntej yuav nce.
High-lub zog kho pob zeb monoliths muaj cov khoom hauv qab no:
- Curvature tsawg tsawg.
- Hnav tsis kam yog siab.
- Lub zog thaum nias - ntawm 50 txog 100 MPa.
Tab sis koj yuav tsum nco ntsoov tias muaj qhov ua tau ntawm cov kab nrib pleb hauv cov pob zeb uas muaj qhov ntom ntom ntom ntom thaum nyem thiab sib cuag nrog dej tib lub sijhawm.
Kev siv cov pob zeb muaj zog ntau
Cov ntaub ntawv zoo li no tau siv thaum lub sijhawm tsim kho cov chaw uas yuav tsum tau txo qhov hnyav ntawm lub tsev thiab txo qhov ntev. Lawv siv thaum koj xav tau los tsim cov khoom lag luam txhim khu kev qha, zoo.
Feem ntau cov pob zeb muaj zog tau pom zoo nyob rau hauv cov xwm txheej hauv qab no:
- Filling floors in industrial buildings.
- Tsim cov tsev khaws khoom rau kev tso cov khoom siv hluav taws xob.
- Kev tsim choj, lwm yam qauv zoo sib xws.
- Tsim ntau lub tsev.
Cov pob zeb muaj zog yog qhov nrov heev ntawm txhua yam khoom siv hauv tsev.
Production
Lub ntsiab tseem ceeb ntawm cov txheej txheem tsim khoom rau kev tsim cov pob zeb ua kom muaj zog yog qhov ua tau zoo ntawm cov khoom siv hauv lub sijhawm ua haujlwm tag nrho.
Qhov no tuaj yeem ua tiav los ntawm kev ua raws li cov cai no:
- Tshwj xeeb high-speed mixers yog siv los tsim cov sib tov.
- Nws yuav tsum tau saib xyuas cov dej noo nyob hauv cov fillers tas li.
- Nws yog ib qho tseem ceeb los sib piv lub sijhawm teem caij thiab lub sijhawm thauj.
- Ib txwm soj ntsuam proportions, dosages.
- Nco ntsoov ntxiv cov khoom xyaw kom raug raws li qhia hauv daim ntawv qhia.
Qhov zoo ntawm cov pob zeb muaj zog kuj yog nyob ntawm kev saib xyuas kom zoo ntawm cov khoom tsim. Cov khoom siv yuav tsum tau them nrog cov khoom ntub dej hauv thawj 3 hnub. Qhov no yuav xyuas kom meejnce kev tiv thaiv ntawm cov khoom tshwm sim rau cov khoom puas tsuaj ntawm ib puag ncig sab nraud.
Cov kws tshaj lij kom tswj tau qhov zoo ntawm cov pob zeb ib txwm saib xyuas cov khoom sib xyaw. Lawv xyuas cov khoom siv, cov yam ntxwv ntawm cov khoom ntim, ntau yam khoom, thiab saib xyuas cov neeg ua haujlwm. Yog tias tsim nyog, txiav txim siab yam tsis ua raws cai.
Zaj lus
High-strength lightweight concretes yog siv nyob rau hauv ntau yam lag luam. Cov khoom siv no ua kom muaj kev ntseeg siab thiab ua haujlwm ntev ntawm lub tsev nyob rau hauv kev tsim kho. Ua ntej xaiv ib qho kev xaiv, nws raug nquahu kom xub sab laj nrog tus tsim kev paub txog.
