Chilichonse chowonjezeredwa ku konkire kupatula simenti, chophatikiza (mchenga) ndi madzi chimatengedwa ngati chosakaniza.Ngakhale kuti zinthuzi sizimafunika nthawi zonse, zowonjezera za konkire zingathandize pazinthu zina.
Zosakaniza zosiyanasiyana zimagwiritsidwa ntchito kusintha zinthu za konkriti.Zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo kupititsa patsogolo ntchito, kukulitsa kapena kuchepetsa nthawi yochiritsa, ndi kulimbikitsa konkire.Zosakaniza zitha kugwiritsidwanso ntchito pazokongoletsa, monga kusintha mtundu wa simenti.
Kuchita bwino komanso kukana kwa konkire pansi pachilengedwe kumatha kupitilizidwa pogwiritsa ntchito sayansi ya uinjiniya, kusintha mawonekedwe a konkire, ndikuwunika mitundu yophatikizika ndi kuchuluka kwa simenti yamadzi.Onjezani zosakaniza ku konkire pamene izi sizingatheke kapena pali zochitika zapadera, monga chisanu, kutentha kwakukulu, kuwonjezereka kwachangu, kapena kutayika kwa nthawi yaitali ku mchere wa deicing kapena mankhwala ena.
Ubwino wogwiritsa ntchito zosakaniza za konkriti ndi izi:
Zosakaniza zimachepetsa kuchuluka kwa simenti yofunikira, zomwe zimapangitsa konkriti kukhala yotsika mtengo.
Zosakaniza zimapangitsa konkriti kukhala kosavuta kugwira ntchito.
Zina zosakaniza zimatha kuwonjezera mphamvu zoyamba za konkire.
Zosakaniza zina zimachepetsa mphamvu zoyamba koma zimawonjezera mphamvu zomaliza poyerekeza ndi konkire wamba.
Kusakaniza kumachepetsa kutentha koyambirira kwa hydration ndipo kumalepheretsa konkriti kuti isagwe.
Zinthu izi zimawonjezera kukana kwa chisanu kwa konkriti.
Pogwiritsa ntchito zinyalala, kusakaniza konkire kumasunga kukhazikika kwakukulu.
Kugwiritsa ntchito zinthuzi kumachepetsa nthawi yoyika konkriti.
Ena mwa ma enzyme omwe ali mumsanganizo ali ndi antibacterial properties.
Mitundu ya konkriti zosakaniza
Zosakaniza zimawonjezeredwa ndi simenti ndi madzi osakaniza kuti zithandize kukhazikitsa ndi kuumitsa konkire.Zosakaniza izi zimapezeka mumitundu yonse yamadzimadzi ndi ufa.Chemical ndi mineral compounds ndi magulu awiri a admixtures.Chikhalidwe cha polojekiti chimatsimikizira kugwiritsa ntchito admixtures.
Kusakaniza kwa Chemical:
Mankhwalawa amagwiritsidwa ntchito pochita ntchito zotsatirazi:
Zimachepetsa mtengo wa polojekiti.
Iwo amagonjetsa mwadzidzidzi konkire kuthira zinthu.
Zimatsimikizira ubwino wa ndondomeko yonse kuyambira kusakaniza mpaka kukhazikitsidwa.
Konzani konkire yolimba.
