Thiab rau cov zeolite powder ua kev ntxiv rau cement, lawv tau pom tias nws yog qhov zoo heev rau kev siv hauv qhov kev kawm txheeb xyuam. Zeolite ntawv yog siv tau los ua qhov cement ib yam li qhov pozzolanic thiab qhov microfilling uas pab tso cia lub cement zoo dua. Tiamsis, cov zeolite powder loss size loss mesh fineness muaj kev cuam tshuam loj rau kev siv zeolite. Rau kev txiav txim siab qhov zoo tshaj plaws rau kev pab tso cia lub strength thiab workability, peb yuav tsum xaiv qhov mesh zoo tshaj plaws. Peb lub neej yog tsim cov zeolite powder zoo tshaj plaws uas muaj cov particle size uas tau muab tswv yim raws li qhov xav tau rau kev siv hauv concrete formulation nyob Runhuabang .
Koj paub txog Mesh Size thiab nws kev cuam tshuam rau Concrete Performance
Rau ntawv zeolite, qhov looj liab yuav tshwm sim rau qhov ntau ntawm cov khoom thiab yog li ntawd yuav tshwm sim rau qhov kev ua haujlwm ntawm cov khoom nyob rau hauv qhov kev sib tw ntawm cement. Cov zeolite ntau yuav muaj qhov ntau ntawm qhov ntsiab thiab yuav tuaj yeem sib koom nrog calcium hydroxide (cov khoom uas tau tsim los ntawm kev sib tw ntawm cement) kom tsim tau cov khoom uas muaj qhov ntsiab ntawm cement. Qhov sib koom no yuav pab txhawj kom qhov ntau ntawm kev sib tw thiab qhov ntau ntawm kev nyab xeeb. Thaum ib leeg, cov zeolite ntau tshaj plaws yuav siv rau qhov kev sib tw ntawm cov khoom ntau kom pab txhawj qhov ntau ntawm kev sib tw ntawm cov khoom ntau rau hauv qhov tshwj xeeb. Qhov ntau ntawm cov khoom ntau yuav pab txhawj qhov ntau ntawm kev sib tw thiab qhov ntau ntawm kev sib tw ntawm cov khoom ntau rau hauv qhov tshwj xeeb, thaum qhov ntau ntawm cov khoom ntau yuav pab txhawj qhov ntau ntawm kev sib tw thiab qhov ntau ntawm kev sib tw ntawm cov khoom ntau rau hauv qhov tshwj xeeb, rau qhov ntau ntawm zeolite uas muaj. Nws yog qhov tseem ceeb kom paub qhov sib koom no kom xaiv qhov looj liab uas zoo rau qhov kev sib tw ntawm cov khoom.
Qhov kev sib koom ntawm zeolite ntau
Zeolite powder (uas los ntawv “superfine zeolite”) yog qhov muaj zeolite ntau dua li zeolite powder uas muaj lub cim ntau. Zeolite uas muaj lub cim ntau heev (median granulometry ~ 3.6 μm), raws li compared to cement, tau pom tias nws muaj qhov density zoo dua thiab muaj qhov strength zoo dua thaum sib tw. Pozzolanic reaction ntawm zeolite thiab calcium hydroxide yuav ua rau cov khoom siv muaj qhov structure zoo dua thiab muaj qhov permeability ntau dua. Zeolite uas muaj lub cim ntau heev yuav xav tau cov dej ntau dua kom siv, uas yuav tsum siv superplasticizers kom tau qhov workability uas xav tau. Superfine zeolite yog qhov muaj txiaj ntsig rau cov qhov siv uas xav tau qhov strength thiab durability zoo thaum sib tw. Tsis tas li ntawd, cov zeolite uas muaj lub cim ntau dua yuav raug xaiv yog tias xav tau qhov dej ntau dua thiab qhov mix design yooj yim dua.
Cov mesh sizes uas cov thawj tswv nyob hauv tsev siv tau xaiv rau cov qhov siv concrete
Los ntawv tshuaj xyuas thiab kev ua haujlwm tau pom tias qhov loj ntawm cov mesh uas zoo tshaj plaws rau kev siv hauv concrete. Cov lus nug los ntawm ob qhov kev siv #80 mesh thiab #200 mesh zeolite tau qhia tias lawv muaj kev ua haujlwm zoo thiab tuaj yeem, thiab yuav tau zoo dua cement mortar tsis muaj lwm yam, tias yog tias kev siv zeolite yog 10-15% ntawm cement. Los ntawm cov ntawv tshuaj xyuas, kev siv zeolite powder uas muaj qhov loj ntawm 200–250 mesh hauv concrete yog qhov tseem ceeb, thiab nws muaj ntau yam qhia tias zoo, xws li: tswj cov dej, ua zoo qhov ratio ntawm dej thiab cement, ua nce qhov viscosity ntawm concrete, thiab ua zoo qhov ability ntawm concrete rau kev siv pump. Ntawm qhov kev tshuaj xyuas txog high performance concrete, lawv siv zeolite uas muaj qhov loj ntawm 5.6–16.7 μm, thiab cov lus nug tau qhia tias kev siv zeolite yuav ua zoo qhov resistance ntawm concrete rau kev poob, ua nce qhov compressive strength ntawm concrete, thiab ua txo qhov autogenous shrinkage ntawm concrete. Cov lus nug no yuav tau siv rau kev xaiv qhov mesh uas zoo tshaj plaws rau kev ua haujlwm uas neeg xav tau.
Tsoom kev nyab xeeb, kev ua haujlwm, thiab kev nyab xeeb
Cov ntsiab lus ntawm zeolite powder rau hauv concrete yog sib koom nrog kev xav tau ntawm txhua qhov kev ua haujlwm. Rau hauv kev ua haujlwm concrete tshwj xeeb uas kev ua haujlwm thiab kev ua haujlwm rau hauv lub tshuab yog sib tshaj, peb xaiv ua zeolite zoo li (200 rau 250 mesh) kom paub zoo dua thiab txo kev haum tsis zoo. Zeolite uas peb siv rau hauv no yog zeolite zoo li heev, uas muaj kev nyob deb deb thiab yuav pab paub zoo dua kev nyob deb deb ntawm concrete zoo li heev lossis concrete zoo li heev, tab sis nws muaj kev nyob deb deb tsis zoo li rau lub sijhawm thaum kawg. Yog tias peb thov cov neeg siv haujlwm ntawm zeolite thiab kev nyob deb deb ntawm zeolite, ces kev nyob deb deb yuav zoo dua. Qhov no yuav tsum sib koom nrog kev hloov kev nyob deb deb ntawm dej thiab cement thiab kev hloov kev nyob deb deb ntawm admixture. Peb cov neeg siv haujlwm yuav txaus siab los pab cov neeg siv haujlwm xaiv cov mesh zoo li rau hauv kev ua haujlwm ntawm concrete, kev nyob deb deb thiab kev ua haujlwm, raws li cov lus qhia ntawm concrete.
Sib tham tog nrog Runhuabang kom muaj zeolite powder tshiab zoo thiab pom txhais rau koj nyob rau hauv kev tsim concrete.
