1) Kusakaniza
Mlingo wa mabala ndi yaying'ono (0,005% -5% ya simenti) ndi zotsatira zake ndi zabwino. Iyenera kuwerengedwa molondola komanso zolemetsa zolemera siziyenera kupitirira 2%. Mtundu wa ma Adntaltures ayenera kutsimikiza mtima kudzera pakuyesa kwa zinthu monga zofuna za ma konkriti, zomanga ndi zinthu zosakaniza. Mukamagwiritsa ntchito mawonekedwe a yankho, kuchuluka kwa madzi mu njirayi kuyenera kuphatikizidwa ndi madzi osakanikirana.
Kugwiritsa ntchito kophatikizana kwa zowonjezera ziwiri kapena zingapo zowonjezera kumapangitsa kukwera kapena kuthamanga kwa yankho, mayankho ayenera kukonzedwa mosiyana ndikuwonjezera osagwirizana.
(2) Madzi ochepetsa mafuta
Pofuna kuonetsetsa kusakanikirana, mankhwala ochepetsa madzi ayenera kuwonjezeredwa mu mawonekedwe a yankho, ndipo ndalamazo zitha kuwonjezeka moyenera monga kutentha kumakwera. Wothandizira madzi ayenera kuwonjezeredwa kwa wosakanizira nthawi yomweyo monga madzi osakanikirana. Mukamayendetsa konkriti ndi galimoto yosakanizika, wothandizira madzi akhoza kuwonjezeredwa asanachotse, ndipo zinthuzo zimachotsedwa pambuyo pa masekondi 60-120. Madzi wamba amachepetsa ma addicturetures ndi oyenera pomanga konkriti pomwe kutentha kochepa kwa tsiku ndi tsiku kuli pamwamba pa 5 ℃. Kutentha kwa tsiku ndi tsiku ndi pansi pa 5 ℃, ayenera kugwiritsidwa ntchito limodzi ndi othandizira oyambira. Mukamagwiritsa ntchito, samalani ndi kunjenjemera ndi kuwongolera. Sinkrete wosakanikirana ndi kuwononga madzi kuyenera kulimbikitsidwa mu gawo loyambira. Pa nthawi yochiritsa, ziyenera kufikira mphamvu ina isanathete. Mankhwala ambiri ochepetsa madzi ambiri amakhala nditatayika kwambiri mukamagwiritsidwa ntchito konkriti. Kutayika kumatha kukhala 30% -50% mu mphindi 30, chifukwa chisamaliro chiyenera kuchitika mukamagwiritsa ntchito.
(3) Wothandizira wa mpweya ndi mpweya wopondera madzi
Konkriti yokhala ndi zofuna za Freeze-Thaw zomwe zimagwiritsidwa ntchito ziyenera kusakanikirana ndi othandizira a mpweya kapena othandizira madzi. Wosaukiridwa konkire ndi ma scerete-owuma sayenera kugwiritsa ntchito othandizira mpweya. Wogulitsa mpweya ayenera kuwonjezeredwa mu mawonekedwe a yankho, choyamba anawonjezera madzi osakanikirana. Wothandizira ndege akhoza kugwiritsidwa ntchito kuphatikiza ndi wogwiritsa ntchito madzi, wothandizila wamphamvu wamphamvu, wobwezeredwa, komanso antiftor. Yankho lokonzekera liyenera kusungunuka kwathunthu. Ngati pali potalika kapena mpweya, uyenera kutenthetsa kuti usungunuke. Konkriti wothandizika wa mpweya ayenera kusakanizidwa mosiyanasiyana, ndipo nthawi yosakanikirayo iyenera kukhala yoposa 3 maminiti 3 ndi ochepera mphindi 5. Nthawi yotuluka kutsanulira iyenera kufupikitsa kuyenera, ndipo nthawi yonjenjemera iyenera kupitirira 20 masekondi kuti musataye zinthu.
(4) wobwerezabwereza komanso wobwezera madzi kuchepetsa mankhwala
Iyenera kuwonjezeredwa mu mawonekedwe a yankho. Pakakhala zinthu zambiri zopanda pake kapena zokhuthuka, ziyenera kusunthidwa kwathunthu musanagwiritse ntchito. Nthawi yosangalatsa imatha kukulitsidwa ndi mphindi 1-2. Itha kugwiritsidwa ntchito limodzi ndi akwati ena. Iyenera kuthiriridwa ndikuchiritsidwa pambuyo pa konkriti kwakhazikitsa. Kubwezeretsa sikuyenera kugwiritsidwa ntchito pomanga konkriti komwe kutentha kocheperako kuli pansi pa 5 ℃, komanso sikuyenera kugwiritsidwa ntchito konkriti kwa konkriti ndi nthunzi yoyambirira.
