Mawu Oyamba

Konkire ndi chinthu champhamvu kwambiri komanso cholimba chomwe chakhala chikugwiritsidwa ntchito pomanga kwazaka zambiri. Ngakhale angagwiritsidwe ntchito pomanga misewu, milatho, nyumba, ndi zomangira zina, imathanso kukhala yosasunthika ikakumana ndi zinthu zoopsa monga kutentha kwambiri, chinyezi, kapena chinyezi. M'nkhaniyi, tikambirana momwe zimatenga nthawi yayitali kuti konkire ikalamba ndikuyipitsa pakapita nthawi, kutilola ife kumvetsetsa bwino zinthu zake ndi zolepheretsa.

Kukalamba ndi Kuwonongeka kwa Konkire

Monga mibadwo ya konkire, imataya mphamvu ndi kusinthasintha chifukwa cha machitidwe a mankhwala pakati pa zigawo zake. Mlingo umene mibadwo konkire zimadalira zinthu zingapo, kuphatikizapo kutentha, chinyezi, kuchiritsa nthawi, ndi kukhudzana ndi zinthu zachilengedwe monga mchere, madzi, ndi zochitika zanyengo yoopsa.

Pa kutentha kwa chipinda (20°C), konkire nthawi zambiri imakalamba pamlingo wa inchi imodzi pachaka. Komabe, monga konkire imakhudzidwa ndi kutentha kwakukulu kapena chinyezi, ukhoza kufulumizitsa ukalamba wake, kumabweretsa nthawi zazifupi mpaka kufika pamalo enaake owonongeka.

Kuchuluka kwa kuwonongeka komwe kumachitika panthawi ya ukalamba kumasiyanasiyana malinga ndi mitundu yeniyeni ya konkire yomwe ikugwiritsidwa ntchito. Mwachitsanzo, konkire yowotchedwa sivuta kusweka ndi kusweka ngati konkire yowuma. Zotsatira zake, konkriti wothamangitsidwa nthawi zambiri imathandizira ukalamba wake pang'onopang'ono, kutenga zaka zingapo kapena makumi angapo kuti ifike pomaliza.

Kutentha ndi Chinyezi

Mlingo umene mibadwo ya konkire imadaliranso kuchuluka kwa chinyezi mu osakaniza. Pamene konkire imasakanizidwa ndi madzi, imakumana ndi mankhwala omwe amachititsa kuti tinthu ting'onoting'ono ta mpweya tipangidwe mkati mwa kusakaniza. Izi zimapanga porosity yomwe imalola konkire kuti ikule ndikugwirizanitsa pansi pa kupanikizika, kuwonjezera mphamvu zake zonse.

Pamene kutentha kumawonjezeka, mlingo umene mibadwo ya konkire imachedwetsa. Izi ndichifukwa choti zomwe zimachitika pakati pa simenti ndi madzi zimawonekera kwambiri, kuchititsa kuti chisakanizocho chikhale chogwirizana kwambiri komanso kuti chisawonongeke ndi ming'alu ndi kusweka.

Kuwonjezera kutentha ndi chinyezi okhutira, mtundu wa konkire womwe ukugwiritsidwa ntchito umakhudzanso zaka zake ndi kutsika kwake. Mitundu ina ya konkire imagonjetsedwa kwambiri ndi kusweka ndi kusweka kusiyana ndi ina, kuwapanga kukhala oyenera kugwiritsidwa ntchito panja pomwe kusintha kwa kutentha ndi kuchuluka kwa chinyezi kungakhale kofunikira.

Nthawi Yokonzekera

Nthawi yochiritsa konkire ndi nthawi yomwe imakhazikika itatha kuthiridwa munthaka kapena sing'anga ina. Nthawi imeneyi imadalira zinthu zingapo, kuphatikizapo mtundu weniweni wa konkire, chinyontho mu osakaniza, ndi kutentha panthawi yochiritsa.

Pamene konkire amaloledwa kuchiza kwathunthu, idzakhala yolimba ndi yolimba. Komabe, ngati sichichiritsika bwino, simenti imatha kuchitapo kanthu ndi chinyezi ndi mpweya mumlengalenga, kupangitsa kuti iphwanyike ndikutulutsa mankhwala owopsa.

Pomaliza, zaka konkire ndi kuwonongeka ndi njira zovuta zomwe zimadalira zinthu zingapo. Ngakhale kuti n'zotheka kuchedwetsa kuyambika kwa njirazi mwa kusakaniza koyenera ndi kuchiritsa, ndikofunikira kuzindikira kuti konkire ndi chinthu cholimba kwambiri chomwe chingalepherebe pansi pamikhalidwe yovuta kwambiri. Pomvetsetsa zaka ndi kuwonongeka kwa konkire, omanga mapulani, mainjiniya, ndipo makontrakitala amatha kupanga zisankho zodziwika bwino posankha ndi kupanga zida zama projekiti awo.
