Kupititsa patsogolo Konkire ndi Zowonjezera

Kupititsa patsogolo konkire ndi zowonjezera kumaphatikizapo kuphatikiza zowonjezera za mankhwala ndi mchere mu konkire yosakaniza kuti muwongolere mawonekedwe kapena mawonekedwe a konkire yowuma. Nawa mitundu ingapo ya zowonjezera zomwe zimagwiritsidwa ntchito kukulitsa konkriti:

1. Zosakaniza Zochepetsa Madzi (Mapulasitiki):
   • Zosakaniza zochepetsera madzi, zomwe zimadziwikanso kuti plasticizers kapena superplasticizers, zimapangitsa kuti ntchito zitheke pochepetsa kuchuluka kwa madzi ofunikira pakusakaniza konkire. Amathandizira kukulitsa kutsika, kuchepetsa tsankho, ndikuwongolera kuyenda kwa konkriti popanda kusokoneza mphamvu.
2. Khazikitsani Retarding Admixtures:
   • Set retarding admixtures amagwiritsidwa ntchito kuchedwetsa nthawi yoyika konkriti, zomwe zimapangitsa kuti pakhale nthawi yayitali yogwira ntchito komanso nthawi yoyika. Amathandiza makamaka nyengo yotentha kapena ntchito zazikulu zomwe zimafunikira mayendedwe atali ndi nthawi yoyika.
3. Khazikitsani Ma Accelerating Admixtures:
   • Set accelerating admixtures amagwiritsidwa ntchito kufulumizitsa nthawi yoyika konkire, kuchepetsa nthawi yomanga ndikuthandizira kuchotsa ndi kutsiriza mofulumira kwa formwork. Iwo ndi opindulitsa mu nyengo yozizira kapena pamene kupeza mphamvu mofulumira chofunika.
4. Zosakaniza Zopatsa Mpweya:
   • Zosakaniza zopangira mpweya zimawonjezedwa ku konkire kuti apange tinthu tating'onoting'ono ta mpweya tosakanikirana, zomwe zimapangitsa kuti azizizira komanso kukhazikika. Amathandizira kuti konkriti igwire bwino ntchito komanso imalumikizana, makamaka nyengo yotentha.
5. Pozzolans:
   • Zipangizo za pozzolanic monga phulusa la ntchentche, fume la silika, ndi slag ndi zowonjezera mchere zomwe zimagwira ntchito ndi calcium hydroxide mu simenti kuti apange mankhwala owonjezera a simenti. Amawonjezera mphamvu, kulimba, ndi kukana kuukira kwa mankhwala ndi kuchepetsa kutentha kwa hydration.
6. Ulusi:
   • Zowonjezera za ulusi, monga chitsulo, zopangira (polypropylene, nayiloni), kapena ulusi wagalasi, zimagwiritsidwa ntchito kulimbitsa mphamvu zolimba, kukana, komanso kulimba kwa konkriti. Amathandizira kuwongolera kusweka ndikuwongolera kukhazikika pamagwiritsidwe azomangamanga komanso osakhazikika.
7. Zosakaniza Zochepetsa Kuchepa:
   • Zosakaniza zochepetsera shrinkage zimagwiritsidwa ntchito pochepetsa kuyanika kwa konkriti, kuchepetsa chiopsezo cha kusweka ndikuwongolera kulimba kwa nthawi yayitali. Amagwira ntchito pochepetsa kuthamanga kwa madzi pamwamba pa kusakaniza konkire.
8. Corrosion Inhibitors:
   • Corrosion inhibitors ndi zinthu zina zomwe zimateteza konkire yolimba kuti isawonongeke ndi ma chloride ayoni, carbonation, kapena zinthu zina zaukali. Amathandizira kukulitsa moyo wautumiki wa konkriti m'malo am'madzi, mafakitale, kapena misewu yayikulu.
9. Zida Zopaka utoto:
   • Zopangira utoto, monga inki ya iron oxide kapena utoto wopangira, amagwiritsidwa ntchito kuwonjezera mtundu ku konkire pazokongoletsa kapena kukongoletsa. Amawonjezera kukopa kowoneka bwino kwa konkriti pamapangidwe omanga ndi kukongoletsa malo.

Pophatikiza zowonjezera izi muzosakaniza za konkriti, mainjiniya ndi makontrakitala amatha kusintha mawonekedwe a konkriti kuti akwaniritse zofunikira za projekiti ndikukwaniritsa zomwe mukufuna kuchita, monga mphamvu, kulimba, kugwirira ntchito, ndi mawonekedwe.
