Mu nyengo zosiyanasiyanachitsulo chamalatazodzitetezera zomanga sizili zofanana, yozizira ndi chilimwe, kutentha kwambiri ndi kutentha otsika, chilengedwe ndi zosiyana yomanga miyeso ndi osiyana.
1.Kutentha kwambiri kwanyengo yopangira malata
Ø Konkire ikamangidwa nthawi yotentha, madzi osakaniza amayenera kugwiritsidwa ntchito potengera njira zoziziritsira kuziziritsa kutentha kwa konkriti pansi pa 30 ℃, ndipo kukhudzidwa kwa kutentha kwakukulu pakutayika kwa konkriti kuyenera kuganiziridwa. Konkire sayenera kusakanizidwa ndi madzi panthawi yoyendetsa.
Ø Ngati zikhalidwe zilipo, ziyenera kuphimbidwa ndi kutetezedwa ku dzuwa kuti zichepetse kutentha kwa mawonekedwe ndi kulimbikitsa; madzi amathanso kuwaza pa formwork ndi kulimbikitsa kuchepetsa kutentha, koma sipayenera kukhala madzi osasunthika kapena omatira mu formwork panthawi yothira konkire.
Ø Magalimoto oyendera konkire akuyenera kukhala ndi zida zosanganikirana, komanso matanki atetezedwe kudzuwa. Ø Konkire iyenera kusakanizidwa pang'onopang'ono komanso mosadodometsedwa panthawi yoyendetsa ndipo nthawi yoyendetsa iyenera kuchepetsedwa.
Ø Zomangamanga zimayenera kuphwanyidwa pamene kutentha kumatsika masana ndipo pamwamba pa konkire payenera kukhala monyowa ndikuchiritsidwa kwa masiku osachepera 7 mutachotsa fomuyo.
2.Njira zomangirachitoliro cha malatanthawi yamvula
Ø Ntchito yomanga mu nthawi ya mvula iyenera kukonzedwa msanga, yesetsani kukonzekera kutsiriza mvula isanagwe, malo opanda madzi ozungulira dzenje kuti madzi ozungulira asalowe mu dzenje.
Ø Onjezani kuchuluka kwa kuyezetsa kokhala ndi madzi amchenga ndi miyala, sinthani kuchuluka kwa konkriti munthawi yake kuti mutsimikizire kusakanikirana kwa konkriti.
Ø Mapaipi a malata ayenera kulimbitsidwa kuti apewe dzimbiri. Ø Polumikiza mapaipi a malata achitsulo, akhazikitsidwe pobisalira mvula kwakanthawi kuti asakokoloke ndi madzi amvula.
Ø Chisamaliro chapadera chiyenera kuperekedwa pachitetezo cha mizere yamagetsi, bokosi lamagetsi la zida zamagetsi zomwe zili pamalowo ziyenera kuphimbidwa ndi njira zodzitetezera ku chinyezi, ndipo mawaya amagetsi azikhala otetezedwa bwino kuti apewe ngozi zotuluka ndi electrocution.
3. Njira zopangira malatachitoliro chachitsulom'nyengo yozizira
Ø Kutentha kozungulira nthawi yowotcherera sikuyenera kutsika kuposa -20 ℃, ndipo kuyenera kuchitidwa kuti tipewe chipale chofewa, mphepo ndi njira zina zochepetsera kusiyana kwa kutentha kwa mfundo zowotcherera. Mgwirizano pambuyo kuwotcherera ndi zoletsedwa kukhudzana ndi ayezi ndi matalala nthawi yomweyo.
Ø The kusakaniza chiŵerengero ndi slump konkire ayenera mosamalitsa ankalamulira kusakaniza konkire m'nyengo yozizira, ndi akaphatikiza sayenera kukhala ndi ayezi ndi matalala ndi mazira mazira. Musanadye, madzi otentha kapena nthunzi ayenera kugwiritsidwa ntchito kutsuka poto yosakaniza kapena ng'oma ya makina osakaniza. Dongosolo la zinthu zowonjezera liyenera kukhala lophatikizana ndi madzi poyamba, ndiyeno onjezerani simenti pambuyo pa kusakaniza pang'ono, ndipo nthawi yosakaniza iyenera kukhala yotalika 50% kuposa kutentha.
Ø Kuthira konkire kuyenera kusankha tsiku ladzuwa ndikuwonetsetsa kuti kwatsirizidwa musanazizire, ndipo nthawi yomweyo, kuyenera kukhala kotetezedwa ndi kusungidwa, ndipo sikuyenera kuzizira mphamvu ya konkire isanakwane pakupanga.
Ø Konkire kunja kwa makina kutentha sikuyenera kutsika kuposa 10 ℃, zida zake zoyendera ziyenera kukhala ndi miyeso yotchinjiriza, komanso kukulitsa kufupikitsa nthawi yoyendera, kutentha mu nkhungu kuyenera kukhala kotsika kuposa 5 ℃.
Ø Magalimoto a konkriti amayenera kukhala ndi njira zotetezera kutentha, komanso kuchepetsa nthawi yoyendera konkriti.
