Kufotokozera zabodza coagulation:

1

Chochitika cha kukhazikitsidwa kwabodza kumatanthauza kuti panthawi ya kusakaniza konkire, konkire imataya madzi mu nthawi yochepa ndipo ikuwoneka kuti ikulowa mu chikhalidwe, koma kwenikweni hydration reaction sikuchitika kwenikweni ndipo mphamvu ya konkire sidzakhala. bwino. Mawonetseredwe enieni ndi osakaniza konkire mwamsanga amataya kugudubuza kwake mkati mwa mphindi zochepa ndipo kumakhala kovuta. Pafupifupi theka la ola limataya madzi ake. Ikangopangidwa pang'onopang'ono, maenje ambiri a zisa amapezeka pamwamba. Komabe, mkhalidwe wa condensation uwu ndi wanthawi yochepa, ndipo konkire imatha kukhalanso ndi madzi enaake ngati itasakanikirana.

Kusanthula zomwe zimayambitsa zabodza coagulation:

Kupezeka kwa coagulation zabodza kumachitika makamaka pazinthu zambiri. Choyamba, pamene zili za zigawo zina mu simenti, makamaka aluminates kapena sulfates, ndi okwera kwambiri, zigawozi zidzachita mofulumira ndi madzi, kuchititsa konkire kutaya fluidity mu nthawi yochepa. Kachiwiri, kufewetsa kwa simenti ndichinthu chofunikira kwambiri chomwe chimakhudza makonzedwe abodza. Zabwino kwambiri simenti particles adzawonjezera enieni padziko m'dera ndi kuonjezera dera kukhudzana ndi madzi, potero kufulumizitsa anachita liwiro ndi kuchititsa onyenga kolowera. Kuphatikiza apo, kugwiritsa ntchito molakwika zosakaniza ndizofalanso. Mwachitsanzo, zosakaniza zochepetsera madzi zimagwira ntchito ndi zigawo zina za simenti kupanga zinthu zosasungunuka. Zinthu zosasungunuka izi zimayamwa madzi ambiri, zomwe zimapangitsa kuti konkriti ichepe. Zinthu monga kutentha ndi chinyezi m'malo omangamanga zingakhudzenso madzi a konkire, zomwe zimapangitsa kuti zikhale zabodza.

 

Njira yothetsera vuto la coagulation yabodza ndi motere:

Choyamba, gwirani ntchito mwakhama posankha simenti. Mitundu yosiyanasiyana ya simenti imakhala ndi mitundu yosiyanasiyana yamankhwala komanso mawonekedwe osinthika, choncho ndikofunikira kusankha mitundu ya simenti yomwe simakhoza kuyambitsa zabodza. Kupyolera mu kufufuza mosamala ndi kuyesa, tikhoza kupeza simenti yomwe ikugwirizana bwino ndi zosowa za polojekiti yamakono, motero kuchepetsa kwambiri chiopsezo cha kukhazikitsidwa kwabodza.

Kachiwiri, tiyeneranso kukhala osamala kwambiri tikamagwiritsa ntchito admixtures. Zosakaniza zoyenera zimatha kusintha bwino ntchito ya konkire, koma ngati ikugwiritsidwa ntchito molakwika kapena ngati zosakaniza zosagwirizana ndi simenti zimasankhidwa, zovuta zokhazikitsa zabodza zitha kuchitika. Choncho, tiyenera zomveka kusintha mtundu ndi mlingo wa admixtures malinga ndi mikhalidwe yeniyeni ya polojekiti ndi makhalidwe a simenti, kapena kukhathamiritsa ntchito yawo mwa compounding kuonetsetsa kuti konkire akhoza kukhala bwino fluidity.

Potsirizira pake, kutentha kwa malo omangamanga ndi chinthu chofunika kwambiri chomwe chimakhudza madzi a konkire. M'malo otentha kwambiri, madzi a konkire amasungunuka mosavuta, zomwe zimapangitsa kuti konkire ikhale yolimba mwamsanga. Kuti tithane ndi vutoli, titha kuchitapo kanthu kuti tichepetse kutentha kosakanikirana, monga kuziziritsa kuphatikizirapo musanasake, kapena kugwiritsa ntchito madzi oundana kusakaniza. Pochepetsa kutentha, titha kuchepetsa kuthamanga kwa konkire, potero tipewe kuchitika kwachinyengo.
