Kuyika mlatho, kukonza simenti, gawo lofunikira la ma jenereta a nthunzi

Kaya tikumanga misewu kapena nyumba, simenti ndi chinthu chofunikira kwambiri.Kutentha ndi chinyezi cha zinthu za simenti ndizofunikira zomwe zimakhudza mphamvu za simenti.Inde, si izi zokha, palinso matailosi a simenti, matabwa a simenti, mapaipi a simenti, ndi zina zotero. Pambuyo powonjezera madzi okwanira ku simentiyo, idzasanduka slurry ya simenti, yomwe imatha kukonzedwa.M'kupita kwa nthawi, simenti idzalimba kukhala yolimba, ndondomekoyi ndi yovuta, ndipo zinthu zambiri zidzakhudza kuthamanga kwa simenti ndi kuuma kwa simenti.

Pakusakaniza, kuthira, kuphatikiza ndi kupanga simenti, pali zofunika kwambiri.Ngati jenereta ya nthunzi ikugwiritsidwa ntchito pochiritsa, kutentha kumatha kuyendetsedwa bwino ndipo pamapeto pake kuumba kwa simenti kumatha kuwongoleredwa.

Popanga ndi simenti, ngati jenereta ya nthunzi ikugwiritsidwa ntchito, idzakhala ndi zotsatira zina pa mphamvu ya zomangamanga za simenti.Tikathira simentiyo, simentiyo imaonekera mumlengalenga ndipo nthawi zina imakhala padzuwa lotentha kwambiri.Madzi amasanduka nthunzi mofulumira ndipo zimakhala zovuta kubwezeretsanso madzi.Idzauma mwachangu, zomwe zimapangitsa kuti simenti ikhale ndi madzi ndipo ingagwiritsidwe ntchito mwachindunji.Zowonongeka, zomwe zimatsogolera ku zinyalala ndi zotsatira zogwira ntchito.

Inde, kuwonjezera pa hydration, kumatanthauza kuumitsa.Mukamagwiritsa ntchito simenti, mwachitsanzo, kuchuluka kwa kuuma kwa nyumbayo kumafunikiranso nthawi yochiritsa pambuyo pakuumba.Panthawiyi, ngati mumagwiritsa ntchito jenereta ya nthunzi, mukhoza kuonetsetsa kuti simenti imakhala ndi chinyezi.Simenti pa kutentha zosiyanasiyana zingakhudze anachita mlingo wa simenti hydration.Kutentha kukakwera, kuchuluka kwa zomwe zimachitika kumachulukira ndipo mphamvu ya condensation imathandizira.Ngati kutentha kuli kotsika kwambiri, momwe zimakhalira zimachepa pang'onopang'ono ndipo mphamvu idzachepa moyenerera.Choncho, pamene tikumanga, ambiri mwa majenereta nthunzi amasungidwa molingana ndi nyengo, kapena kutentha kwa m'deralo, malo, ogwiritsa ntchito, ndi khalidwe la madzi, ndi zina zotero, ndikuwongolera momwe simenti imayendera komanso kuuma kwa simenti kuti iwononge katundu wa simenti.Kuthamanga ndi kuchedwa kwa mphamvu yapangidwe ya mankhwala.

Zinthu za simenti zikasungidwa pogwiritsa ntchito ma jenereta athu a nthunzi, zimatha kusinthidwa malinga ndi zomwe makasitomala amafuna.Kupanikizika kumakhala kokhazikika ndipo kumatha kukwaniritsa zosowa za malo osiyanasiyana opangira komanso nyengo.Mphamvuyo imathanso kusinthidwa mumagiya angapo.Kuchuluka kwa simenti kukakhala kosiyana, kuchuluka kwa nthunzi komwe kumafunikira kumakhala kosiyana, komwe kumatha kupulumutsa mphamvu ndikuteteza chilengedwe.

Choncho, pogwiritsira ntchito jenereta ya nthunzi, imakhala ndi ubwino wambiri komanso kupulumutsa mphamvu.Ndikosavuta komanso kupulumutsa mphamvu kusankha jenereta ya nthunzi kuti musunge zinthu za simenti.Jenereta ya nthunzi ndi zipangizo zoyeretsera zotentha kwambiri komanso zothamanga kwambiri.Kuthamanga kwambiri komanso kutentha kwambiri komwe kumapangidwa kumatha kuyeretsa ndi kupha tizilombo toyambitsa matenda m'makampani azachipatala, komanso kungagwiritsidwe ntchito kuzinthu zamagetsi.Imagwira ntchito m'mafakitale ambiri, monga uinjiniya wa biochemical, makampani azachipatala, mafakitale opanga chakudya, makina onyamula katundu, zovala, kafukufuku woyesera, kuyeretsa kutentha kwambiri, mafakitale omanga, ndi zina zambiri.
