Khwerero 1: kuyesa alkalinity ya simenti

Yesani kuchuluka kwa pH ya simenti yomwe mukufuna, ndipo gwiritsani ntchito pH, mita ya pH kapena cholembera cha pH kuyesa. Zotsatira zoyesera zingagwiritsidwe ntchito podziwiratu: ngati kuchuluka kwa alkali sungunuka mu simenti ndi yayikulu kapena yaying'ono; kaya admixture mu simenti ndi acidic kapena inert zinthu monga mwala ufa, zimene zimapangitsa pH kukhala otsika.

Gawo 2: kufufuza

Gawo loyamba la kafukufukuyu ndikupeza zotsatira zowunika za clinker za simenti. Werengani zomwe zili mu mchere zinayi mu simenti: tricalcium aluminate C3A, tetracalcium aluminoferrite C4AF, tricalcium silicate C3S ndi dicalcium silicate C2S.

Gawo lachiwiri la kafukufukuyu ndikumvetsetsa kuti ndi zinthu zotani zomwe zimaphatikizidwa pamene klinka ikuphwanyidwa mu simenti ndi kuchuluka kwake komwe kumawonjezeredwa, zomwe zimathandiza kwambiri pofufuza zomwe zimayambitsa magazi a konkire komanso nthawi yokhazikika (yotalika kwambiri, yochepa kwambiri).

Gawo lachitatu la kafukufukuyu ndikumvetsetsa kusiyanasiyana komanso kuwongolera kophatikiza konkriti.

Khwerero 3: Pezani kuchuluka kwa mlingo wokwanira

Dziwani kuchuluka kwa mlingo wa chochepetsera madzi chogwira ntchito kwambiri chomwe chimagwiritsidwa ntchito popanga simentiyi. Ngati awiri kapena kuposerapo ochepetsera madzi amphamvu kwambiri akusakanikirana, pezani mlingo wokwanira wa mlingo kudzera muyeso la phala la simenti malinga ndi kuchuluka kwa kusakaniza. Kuyandikira kwa mlingo wa chochepetsera madzi othamanga kwambiri ndi mlingo wokwanira wa simenti, zimakhala zosavuta kuti mukhale osinthika bwino.

Khwerero 4: Sinthani digiri ya pulasitiki ya clinker kuti ikhale yoyenera

Sinthani mlingo wa alkali sulfation mu simenti, ndiye kuti, digiri ya pulasitiki ya clinker pamlingo woyenera. Kuwerengera kwa mtengo wa SD wa digiri ya plasticization ya clinker ndi: SD=SO3/(1.292Na2O+0.85K2O) Zomwe zili pagawo lililonse zalembedwa pakuwunika kwa clinker. Mtengo wa SD ndi 40% mpaka 200%. Ngati ndi otsika kwambiri, ndiye kuti pali trioxide ya sulfure yocheperako. Mchere wochepa wokhala ndi sulfure monga sodium sulphate uyenera kuwonjezeredwa kusakaniza. Ngati ndipamwamba kwambiri, zikutanthauza kuti molekyu ndi yaikulu, ndiko kuti, pali sulfure trioxide yambiri. Mtengo wa pH wa kusakaniza uyenera kuwonjezeka pang'ono, monga sodium carbonate, caustic soda, etc.

Khwerero 5: Yesani-sakanizani zophatikizika ndikupeza mtundu ndi mlingo wa othandizira

Pamene khalidwe mchenga ndi osauka, monga mkulu matope okhutira, kapena pamene onse yokumba mchenga ndi mchenga superfine ntchito kusakaniza konkire, pambuyo ukonde slurry mayeso amapeza zotsatira zogwira mtima, m`pofunika kupitiriza kuchita mayeso matope kuti zina kusintha kusinthasintha ndi admixture.

Khwerero 6: Mayeso a konkire Poyesa konkire, kuchuluka kwa kusakaniza kuyenera kukhala kosachepera 10 malita

Ngakhale slurry ya ukonde itasinthidwa bwino, sizingakwaniritse zoyembekeza mu konkire; ngati slurry ya ukonde sichinasinthidwe bwino, konkire ikhoza kukhala ndi mavuto aakulu.Pambuyo pa kuyesedwa kochepa kopambana, nthawi zina ndalama zambiri zimafunika kubwerezedwa, monga 25 malita mpaka 45 malita, chifukwa zotsatira zikhoza kukhala zosiyana pang'ono. Pokhapokha ngati mayeso angapo a konkriti apambana pomwe kusintha kosinthika kumatha kumaliza.

Khwerero 7: Sinthani kusakaniza konkriti

Mukhoza kuonjezera kapena kuchepetsa kuchuluka kwa mchere wosakaniza moyenerera, ndikusintha kusakaniza kumodzi kukhala kuwirikiza kawiri, ndiko kuti, gwiritsani ntchito zosakaniza ziwiri zosiyana nthawi imodzi. Palibe kukayika kuti kuphatikiza pawiri kuli bwino kuposa kusakanizikana limodzi; kuwonjezeka kapena kuchepetsa kuchuluka kwa simenti kumatha kuthetsa zofooka za kumata kwa konkire, kutayika kwachangu komanso kutaya magazi konkire, makamaka kukhudzana ndi mchenga; kuonjezera pang'ono kapena kuchepetsa kuchuluka kwa madzi; kuonjezera kapena kuchepetsa chiŵerengero cha mchenga, kapena kusintha pang'ono mtundu wa mchenga, monga kusakaniza mchenga wouma ndi wabwino, mchenga wachilengedwe ndi mchenga wochita kupanga, ndi zina zotero.
