Kev siv cov khoom sib xyaw ua ke zoo heev txhim kho cov khoom ntws ntawm cov pob zeb thiab txo cov khoom siv cementitious hauv pob zeb.Yog li ntawd, pob zeb admixtures yog dav siv.Hauv kev xyaum ua haujlwm ntev, nws tau pom tias ntau qhov chaw sib tov muaj kev nkag siab yuam kev ntawm kev siv cov khoom sib xyaw ua ke, ua rau cov pob zeb tsis txaus, kev ua haujlwm tsis zoo, lossis cov nqi sib tov ntau dhau.
Kev paub txog kev siv cov khoom sib xyaw kom raug tuaj yeem ua kom lub zog ntawm cov pob zeb ua kom cov nqi sib xyaw tsis hloov;los yog txo cov nqi sib xyaw thaum khaws lub zog ntawm pob zeb;khaws cov dej-cement piv tsis hloov, txhim kho kev ua haujlwm ntawm pob zeb.
A.Kev nkag siab tsis meej txog kev siv cov khoom sib xyaw
(1) Yuav cov khoom sib xyaw ntawm tus nqi qis
Vim muaj kev sib tw ua lag luam hnyav, qhov chaw sib xyaw ua ke muaj kev tswj hwm nruj ntawm kev yuav khoom ntawm cov khoom siv raw.Cov chaw sib xyaw txhua qhov kev cia siab yuav cov khoom siv raw ntawm tus nqi qis tshaj plaws, thiab tib yam mus rau cov khoom sib xyaw ua ke.Cov chaw sib xyaw ua ke ua rau tus nqi yuav khoom ntawm cov khoom sib xyaw, uas yuav ua rau muaj kev cuam tshuam rau cov neeg tsim khoom lag luam txo lawv cov qib zoo.Feem ntau, cov qauv kev lees paub rau cov khoom sib xyaw tsis tshua muaj nyob rau hauv cov ntawv cog lus ntawm kev sib xyaw cov nroj tsuag.Txawm hais tias muaj, nws tsuas yog ua raws li lub teb chaws tus qauv yuav tsum tau ua, thiab lub teb chaws tus qauv yuav tsum yog feem ntau cov qauv qis tshaj.Qhov no ua rau lub fact tias thaum admixture manufacturers yeej qhov kev sib tw ntawm tus nqi qis, cov admixtures lawv muab yog cov tsis zoo thiab feem ntau NW nyuam qhuav ua tau raws li lub teb chaws tus txheej txheem, ua rau nws nyuaj rau ua tau raws li qhov yuav tsum tau ntawm lub chaw nres tsheb sib tov rau kev siv. cov khoom xyaw.
(2) Txwv cov khoom ntxiv
Qhov kev txiav txim siab theem ntawm qhov chaw sib tov nruj me ntsis saib xyuas cov nqi sib xyaw, thiab txawm tias muaj cov kev xav tau meej meej ntawm cov cement ntau npaum li cas thiab cov tshuaj sib xyaw.Qhov no yuav inevitably ua rau lub tuam tsev technical tsis txaus siab los ntawm kev txiav txim siab txheej txheem's ntau npaum li cas yuav tsum tau rau additives thaum tsim cov mix ratio.
(3) Tsis muaj kev saib xyuas zoo thiab kev sim ua pov thawj ntawm cov khoom sib xyaw
Tam sim no, rau kev tshuaj xyuas cov khoom sib xyaw, feem ntau cov chaw sib xyaw ua ib lossis ob qho ntawm cov kev qhia xws li cov ntsiab lus, cov dej txo qis, qhov ntom ntom, thiab fluidity ntawm cov slurry huv.Ob peb qhov chaw sib xyaw ua cov kev sim ua vaj tse.
Hauv kev xyaum ua ntau lawm, peb pom tias txawm tias cov ntsiab lus ntawm cov khoom siv, cov dej txo qis, qhov ntom ntom, fluidity thiab lwm yam kev qhia ntawm cov khoom sib xyaw ua tau raws li qhov yuav tsum tau ua, qhov kev ntsuam xyuas pob zeb tseem yuav tsis ua tiav cov txiaj ntsig ntawm kev sib tw thawj zaug, uas yog, Cov dej ua kom txo qis tus nqi tsis txaus., los yog tsis zoo adaptability.
B. Qhov cuam tshuam ntawm kev siv tsis raug ntawm cov khoom sib xyaw ntawm cov pob zeb zoo thiab cov nqi
Vim tias qhov tsis zoo ntawm cov khoom sib xyaw tau yuav ntawm tus nqi qis, txhawm rau ua tiav cov txiaj ntsig txo cov dej txaus, cov tuam txhab kev lag luam feem ntau nce ntau npaum li cas ntawm cov khoom sib xyaw, ua rau cov khoom siv tsis zoo thiab ntau lub hom phiaj.Ntawm qhov tsis sib xws, qee qhov chaw sib xyaw nrog kev tswj xyuas zoo thiab kev sib xyaw ua ke zoo dua tus nqi tswj kev siv cov khoom sib xyaw kom zoo dua thiab cov nqi siab dua.Vim tias qhov zoo thiab siv tsawg dua, chav tsev nqi ntawm cov khoom sib xyaw txo qis.
Qee qhov chaw sib tov txwv cov khoom sib xyaw.Thaum cov pob zeb tawg tsis txaus, lub tuam txhab kev lag luam yuav txo qis cov dej noo ntawm cov xuab zeb thiab pob zeb, los yog ua kom cov dej siv rau ib chav tsev ntawm cov pob zeb, uas yuav ncaj qha ua rau txo qis ntawm cov pob zeb.Technical departments uas muaj kev nkag siab zoo ntawm kev ua tau zoo yuav indirect los yog ncaj qha nce lub unilateral water noj ntawm cov pob zeb thiab nyob rau tib lub sij hawm tsim nyog nce tus nqi ntawm cov cementitious cov ntaub ntawv (ua kom cov dej-cement piv tsis hloov), uas ua rau ib tug nce nyob rau hauv tus nqi ntawm cov cementitious khoom. qhob mix ratio.
Qhov chaw sib tov tsis muaj kev saib xyuas zoo thiab kev sim tshuaj ntsuam xyuas cov khoom sib xyaw.Thaum qhov zoo ntawm additives fluctuates (txo), lub tuam tsev technical tseem siv cov thawj mix ratio.Txhawm rau kom ua tau raws li qhov yuav tsum tau ua ntawm cov pob zeb ua pob zeb, cov dej siv tiag tiag ntawm cov pob zeb nce, cov dej-cement piv tau nce, thiab lub zog ntawm cov pob zeb txo qis.
