Q: Kodi kuchiritsa konkriti ndi chiyani?

A:
Konkire ndiye mwala wapangodya wa nyumba. Ubwino wa konkire umatsimikizira ngati nyumba yomalizidwayo ndi yokhazikika. Pali zinthu zambiri zomwe zimakhudza ubwino wa konkire. Pakati pawo, kutentha ndi chinyezi ndizovuta kwambiri. Pofuna kuthana ndi vutoli, gulu lomanga nthawi zambiri limagwiritsa ntchito nthunzi ku Konkire imachiritsidwa ndikukonzedwa.

Cholinga chachikulu cha nthunzi ndikuwongolera kulimba kwa konkriti. Kukonza konkire ndi gawo lofunika kwambiri pa ntchito yomanga konkire ndipo kumagwirizana mwachindunji ndi khalidwe la zomangamanga la polojekiti yonse. Chitukuko chachuma chamakono chikukula mofulumira komanso mofulumira, ntchito zomanga zikukula kwambiri, ndipo kufunikira kwa konkire kukukulirakulira.

Choncho, ntchito yokonza konkire mosakayikira ndi nkhani yofunika kwambiri pakali pano. Konkire ikatsanulidwa, chifukwa chake imatha kulimba pang'onopang'ono ndikuumitsa makamaka chifukwa cha hydration ya simenti. Kuthira madzi kumafuna kutentha ndi chinyezi choyenera. Choncho, pofuna kuonetsetsa kuti konkire ili ndi mikhalidwe yoyenera yowumitsa, mphamvu zake zidzapitirira kuwonjezeka. , konkire iyenera kuchiritsidwa.

Konkire kuchiritsa mu nyengo yozizira
Kutentha kwabwino kwa konkriti ndi 10 ℃-20 ℃. Ngati konkire yomwe yangotsanuliridwa kumene ili m'malo ochepera 5 ℃, konkire imawumitsidwa. Kuzizira kumayimitsa hydration yake ndipo pamwamba pa konkriti pamakhala crispy. Kutaya mphamvu, ming'alu yoopsa ikhoza kuchitika, ndipo kuchuluka kwa kuwonongeka sikudzabwezeretsedwa ngati kutentha kumakwera.

Chitetezo pa kutentha kwakukulu ndi malo owuma
Chinyezi n'chosavuta kwambiri kusungunuka pansi pauma komanso kutentha kwambiri. Ngati konkire imataya madzi ochulukirapo, mphamvu ya konkire pamtunda wake imachepetsedwa mosavuta. Panthawi imeneyi, ming'alu ya shrinkage yowuma imakhala yovuta kuchitika, yomwe imakhala ming'alu ya pulasitiki chifukwa cha kukhazikitsidwa msanga kwa konkire. Makamaka panthawi yomanga konkire m'chilimwe, ngati njira zosamalira sizikuyendetsedwa bwino, zochitika monga kukhazikitsidwa msanga, ming'alu ya pulasitiki, kuchepetsa mphamvu ya konkire ndi kukhazikika zidzachitika kawirikawiri, zomwe sizimangokhudza ntchito yomanga, komanso chinthu chofunika kwambiri. kupanga mapangidwe motere. Ubwino wonse wa chinthucho sungatsimikizidwe.

Nobeth kuchiritsa nthunzi jenereta amapanga mkulu-kutentha nthunzi mu nthawi yaifupi kuchita nthunzi machiritso pa prefabricated zigawo zikuluzikulu, kupanga yoyenera kutentha ndi chinyezi chilengedwe kulimbitsa ndi kuumitsa konkire, kuwongolera dzuwa ndi kupita patsogolo kwa zomangamanga konkire.
