Chofunika Kwambiri Pakuwunika Kutentha kwa Konkriti ndi Chinyezi Pansi pa Mikhalidwe Yanyengo Yovuta

Ndikofunikira Kwambiri Pakuwunika Kwa Konkriti Ndi Chinyezi Panyengo Yovuta Kwambiri

Nyengo imakhudza kwambiri kuchiritsa ndi mphamvu ya konkriti.M'nyengo yozizira, konkire imachiritsa pang'onopang'ono, zomwe zimachepetsa mphamvu zake.Kwa konkire yotentha, mavuto amatha kuchitika pamene chinyontho chimachotsedwa pa slab ya konkire mofulumira kwambiri.Izi ziyenera kuyang'aniridwa ndi zolondolamasensa kutentha ndi chinyezikuonetsetsa kuti simenti ikuyenda bwino.

1. Kuthira konkriti

Zosakaniza monga mchenga ndi miyala zikasakanizidwa ndi simenti ndi madzi, kutentha kumawonjezeka nazo.Kutentha kochokera munjira yotenthayi kumatchedwa kutentha kwa hydration.Mphamvu ya hydration ndi yomwe imapangitsa konkire kuumitsa.

Pa hydration ndondomeko, zosiyanasiyana mankhwala zimachitikira nthawi imodzi.Izi zimabweretsa "hydration products".Ma hydration awa amachititsa kuti tinthu tating'onoting'ono ta mchenga, miyala, ndi zinthu zina zizigwirizana ndikupanga midadada ya konkriti.

2. Magawo asanu a kusintha kwa kutentha kwa konkire

Kusintha kwa kutentha mu konkire ndi njira yovuta yomwe imakhudza kwambiri mphamvu ya konkire.Njirayi imagawidwa m'magawo asanu osiyanasiyana.Gawo lirilonse liri ndi nthawi yeniyeni ndi machitidwe a mankhwala, malingana ndi kusakaniza konkire.

a.Kuchita koyamba.

Gawo loyamba la hydration lidzayamba madzi atangotsanuliridwa pa simenti.Kenaka, kuwonjezeka kwadzidzidzi kwa kutentha kumayembekezeredwa.Izi zidzachitika mwachangu ndipo zimatha pafupifupi mphindi 15-30, kutengera mtundu wa simenti yomwe imagwiritsidwa ntchito.

b.Dormancy nthawi.

Pambuyo koyamba anachita, pawiri kuphimba pamwamba pa simenti particles, zomwe zidzachititsa pang`onopang`ono mlingo wa hydration.Izi zikachitika, ndi gawo lachiwiri la kusintha kwa kutentha kwa konkire, komwe kumatchedwanso kuti induction phase, yomwe ndi nthawi yolowera pamene konkire isanawumitsidwe, ndipo zoyendetsa ndi kuyika konkire ziyenera kukwaniritsidwa. nthawi imeneyi.

c.Nthawi ya mphamvu mathamangitsidwe.

Pagawo lachitatu, konkire imayamba kukhala ndi mphamvu ndipo motero imakhazikika, imasanduka misa yolimba komanso yolimba.Kutentha kwa hydration kumawonjezeka pang'onopang'ono mpaka kufika pamtunda wake wapamwamba.Kutentha ndi chinyezi panthawiyi zimayang'aniridwa pogwiritsa ntchito masensa a kutentha ndi chinyezi, zomwe zimapangitsa kuti konkire ikhazikike pang'onopang'ono ndikufika pamtunda woyenera.Kutentha kophatikizana kwamitundu yambiri ya Hengko ndi chinyezi kumakwaniritsa zosowa zosiyanasiyana zamakasitomala, monga kupereka mitundu ya digito yapamwamba kwambiri.kutentha ndi chinyezi sensor probes: Kuti mutumize chotumizira, mufunika kafukufuku wolumikizira.Mwachitsanzo, gwiritsani ntchito kafukufuku wokhala ndi chidziwitso chapamwamba, chokhazikika chokhazikika cha chinyezi kwa nthawi yayitali ya kutentha ndi malo osiyanasiyana;Ukadaulo waukadaulo wanzeru: kusintha kosavuta kwa ma probe, mawonekedwe a digito opatsira, ndi malingaliro anzeru owongolera.

d.Kutsika.

Gawo lachinayi limachitika panthawi yomwe kutentha kwa hydration kumafika pachimake kutentha kwake.Kutentha kwa hydration kumayamba kuchepa pamene hydrate yomwe yapangidwa imakhala yotetezera gawo lomwe silinachitepo.Mphamvu zambiri zapezedwa ndipo nthawi zambiri zimakhala kwa maola angapo, ngati osati miyezi.Pambuyo pa mphamvu yofunidwayo, fomuyo imachotsedwa panthawiyi.

e.Khazikika.

Njira ya hydration imamalizidwa pamene gawo la 5 likufika.Kuyankha kotentha kwa hydration kumachedwa, pafupifupi pamlingo wofanana ndi mu gawo logona.Gawo lomaliza la ndondomeko ya hydration limatha masiku, miyezi, kapena zaka mpaka litatha ndikupeza mphamvu zake zomaliza.

3. Kufunika kwakuwunika kutentha ndi chinyezi

Gawo lirilonse la ndondomeko ya hydration limakhala ndi kutentha kosiyana.Choncho, kuyang'anira kosasinthasintha ndi kuwonetsetsa kwa siteji iliyonse ndikofunikira kuti pakhale kutentha kochepa kovomerezeka panthawi yonseyi.Tsoka ilo, nyengo yoipitsitsa imapangitsa kutenthaku kukhala kovuta kwambiri kusunga.

Kutengera nyengo, kutentha kwa konkriti kumasungidwa pakati pa 40-90F.M'nyengo yozizira, kutentha kwa konkire kumasungidwa pamwamba pa 40F.Mosiyana ndi izi, malire a kutentha kwa nyengo yotentha ndi 90F.

Kusamala kumatengedwa kusakaniza, kuyika ndi kusunga konkire nthawi yotentha.Makontrakitala akuyenera kutsatira malire a kutentha powunika.Apo ayi, hydration sichidzachitika bwino ndipo mavuto angabwere.

Kuipa kwina kwa nyengo yozizira ndi kuzizira msanga kwa konkire.Izi zimachepetsanso mphamvu ya konkire mpaka 50%.Pankhaniyi, ndikofunika kuteteza konkire ku kuzizira.

Kutentha kwa konkire mu nyengo yovuta kumasiyana malinga ndi momwe chilengedwe chilili.Njira zodzitetezera zitha kugwiritsidwa ntchito moyenera ngati pali data yolondola ya kutentha ndi chinyezi.Deta yolakwika komanso kuchedwa kulandilidwa chifukwa cha zolakwika za anthu kungayambitse zisankho zolakwika.Kuwunika ndi zida zanzeru monga Hengkomafakitale-grade kutentha ndi chinyezi masensaimatha kuthandiza ogwiritsa ntchito kuyeza zolondola.

Muli Ndi Mafunso Ndimakonda Kudziwa Tsatanetsatane Wowunikira Chinyezi Panyengo Yovuta Kwambiri, Chonde Khalani Omasuka Lumikizanani Nafe Tsopano.
