Kodi Elastic Modulus Mu Konkire Imachulukira Bwanji?

The Elastic modulus mu konkire inawonjezeka, monga momwe anthu ambiri amayembekezera. Chochitika ichi chalembedwa kudzera muzoyesera zosiyanasiyana ndi kusanthula kochitidwa ndi akatswiri a masamu, mainjiniya, ndi ogwira ntchito yomanga kwa zaka makumi angapo.

Kumayambiriro kwa zaka za m’ma 1960, John James Adams adanenanso kuti modulus yotanuka ya konkire idakwera kuchokera pafupifupi 32 N/m^3 pa firiji mpaka 40-50 N/m^3 pa firiji. Panthawi ino, konkire inakhala yokhazikika komanso yolimba kuposa kale lonse. Komabe, kuwonjezeka uku sikunali njira yofananira, koma m'malo mwake kuwonjezeka kwapang'onopang'ono komwe kunayamba kuchepa pang'onopang'ono pamene mawonekedwe a konkire adafooka pakapita nthawi.
Chinthu chimodzi chochititsa chidwi cha kuwonjezeka kumeneku kwa elasticity ndi gawo lomwe limagwira popewa kugwa pansi pa nkhawa. Pamene elasticity ikuwonjezeka, konkire imasinthasintha mosavuta, kulola kuti itenge mphamvu zambiri ndikukana mapindikidwe. Izi zitha kuteteza matumba a mpweya kapena zinthu zina mkati mwa konkire zomwe zimatha kugwa pakatha katundu..
Chinthu chinanso chofunikira chomwe chimathandizira kuwonjezeka kwa elasticity ndi khalidwe lokha. Monga geometry ya konkire imakumana ndi zovuta zonse, katundu wake amasintha mofulumira. Izi zimapangitsa kuti pakhale ma microcracks ndi machitidwe ena ong'aluka omwe amalola kuyenda bwino kwa mpweya ndi madzi mkati mwa dongosolo.. Izi, panthawi yake, kumathandiza kukhalabe ndi mphamvu ndi kulimba kwa konkire.
Pomaliza, kugwiritsa ntchito ukadaulo wowongolera kutentha ndi chinthu chofunikira chomwe chimathandizira kuwonjezereka kwa elasticity mu konkriti. Polamulira kutentha kwa konkire isanatsike, mainjiniya amatha kuonetsetsa kuti akusamalidwa bwino, kuchepetsa chiopsezo chomanga zolakwika ndikuwongolera magwiridwe antchito onse.

Zonse, kuwonjezeka kwa modulus yotanuka konkire kumapereka phindu lalikulu pakuchita komanso kukhazikika. Ngakhale pangakhale zina za momwe kuwonjezeka kumeneku kwakhudzira kumanga konkire, akatswiri ambiri amakhulupirira kuti yathandiza kwambiri kuti konkire ikhale yolimba komanso yolimba kumakampani omanga amasiku ano..
