Makhalidwe Azigawo Za Konkire

6 mphindi kuwerenga

Magulu onsewa amadziwika kuti ndizodzaza ndi ma inert, zomwe zimapanga 60 mpaka 80% polemera konkriti ndi 70 mpaka 85% polemera. Chigawochi chagawika mitundu iwiri yosiyana: yovuta komanso yabwino. Ma coarse aggregates nthawi zambiri amakhala akulu kuposa 4.75 mm, pomwe magulu abwino amakhala ocheperako kuposa 4.75 mm. Mphamvu yokakamiza ya chipindacho ndi chinthu chofunikira posankha chidacho.

Mwala umapanga m'mphepete mwazitali komanso zigawo zazitali zomwe zimakhala ndizokwera kwambiri mpaka kuchuluka kwake komanso zomangika bwino, koma zimafuna slurry yochulukirapo kuti ipange zosakanikirana. Mutha kupeza zinthu zabwino kwambiri pa zomangamanga pa intaneti.

Makhalidwe Azigawo Za Konkire

Zida zina zamagulu amtunduwu zimatha kukopa zinthu zakusakanikirana konkriti. Izi ndi izi.

  1. zikuchokera

Ndizoletsedwa kugwiritsa ntchito magulu opangidwa kuchokera kuzinthu zomwe zimagwiritsidwa ntchito ndi alkali mu simenti ndikupangitsa kukula kwambiri, kulimbana ndi kuwonongeka kwa konkriti. Chipangizocho chikuyenera kuyesedwa kuti mudziwe ngati zinthuzo zilipo mgululi.

  1. Kukula ndi mawonekedwe

Kukula ndi mawonekedwe amitundu yonseyi zimakhudza kwambiri simenti yomwe imafunikira pakusakaniza kwa konkriti, zomwe pamapeto pake zimakhudza magwiridwe antchito a konkriti. Chigawo chachikulu kwambiri chotheka chiyenera kugwiritsidwa ntchito popanga konkriti wachuma. Wogulitsa Omanga Laker imapereka mitundu yonse kukula ndi mawonekedwe.

Kumbukirani kuti kukula ndi mawonekedwe a tinthu tating'onoting'ono timakhudza kwambiri magwiridwe antchito atsopano a konkire kuposa konkire wolimba.

  1. Pamwamba kapangidwe

Kukula kwa mgwirizano wolimba pakati pa tinthu tating'onoting'ono ndi simenti slurry zimadalira mawonekedwe akunyumba, mawonekedwe oyipa komanso mawonekedwe apadziko lonse lapansi.

Ngati pamwamba pake pali pakhola koma paliponse, pamakhala mphamvu zomatira kwambiri. Pamalo ophatikizika am'mapiri, mphamvu zomata zimawonjezeka chifukwa cha kuuma kwa simenti slurry mu pores.

  1. Kulemera kwake mwapadera

Kuchuluka kwa kulemera kwake kwa uvuni komwe kumayikidwa kumatenthetsa mpaka 100 mpaka 1100 ° C kwa maola 24 mpaka kulemera kwa kuchuluka kofanana kwa madzi komwe kumalowetsedwa ndi gulu lodzaza louma lomwe limatchedwa kukula kwa gulu lonselo.

Kulemera kwake ndi njira yodziwitsira kugwiritsa ntchito kwamagulu. Mphamvu yokoka yotsika nthawi zambiri imawonetsa zida zopindika, zofooka komanso zoyamwa, pomwe mphamvu yokoka yayikulu imawonetsa zinthu zabwino.

  1. Mlingo waukulu

Amatanthauzidwa ngati kulemera kwa unit yomwe imafunika kudzaza chidebe cha voliyumu. Kawirikawiri amafotokozedwa mu kilogalamu pa lita.

  1. Porosity ndi mayamwidwe

Chifukwa cha thovu, timabowo tating'onoting'ono tomwe timapanga pathanthwe pomwe magma osungunuka amalimba amatchedwa pores. Miyala yokhala ndi miyala yotchedwa poore imatchedwa porous miyala.

Kuyamwa kwamadzi kumatha kufotokozedwa ngati kusiyana pakati pa kulemera kwa gawo lowuma kwambiri ndi kulemera kwa gulu lokwanira munthawi zowuma.

  • Kutengera ndi chinyezi chomwe chili mgawomo, chimatha kukhalapo pamikhalidwe iliyonseyi.
  • Chipangizocho ndi chouma kwambiri (palibe chinyezi)
  • Gulu lowuma (chinyezi china pores)
  • Zowonjezera zokhala ndi malo owuma (ma pores adadzazidwa ndimadzi, koma palibe madzi pamtunda)
  • Magulu onyowa kapena onyowa.
  1. Mchenga wambiri

Titha kutanthauziridwa kuti pansi pamvula, mchenga wokwanira (mwachitsanzo)) ukuwonjezeka poyerekeza ndi kuchuluka kwa mchenga wouma kapena wokwanira. Kuchuluka kwa kuchuluka kwa mchenga wonyowa mpaka kuchuluka kwa mchenga wouma kumatchedwa koyefishienti yowonjezera.

Madzi akawonjezeredwa pamchenga wouma komanso wosasunthika, filimu yopyapyala yamadzi imapanga mozungulira mchenga. Chifukwa chakumangika kwapadziko lapansi, mpweya pakati pamchenga ndi kanema wamadzi amakonda kukankhira tinthu tating'onoting'ono patali, kukulitsa voliyumu.

  1. Gawo lazachuma

The fineness modulus ndichinthu champhamvu chomwe chimapezeka powonjezera ndikugawa kuchuluka kwakachulukidwe kamene kamatsalira pa sefa iliyonse mu 80 mm mpaka ma microns a 150 ndikugawa ndi 100.

Gawo labwino kwambiri limagwiritsidwa ntchito kuti mumvetsetse kuchuluka kwake. Mtengo wokulirapo wa gawo loyera umawonetsa kuchuluka kopitilira muyeso, ndipo mtengo wocheperako wa gawo loyera umawonetsa kuchuluka kwathunthu.

  1. Malo enieni a chipangizocho

Pamwamba pamiyeso yolemera yazinthu zimatchedwa malo enieni. Iyi ndiye njira yosalunjika ya kalasi yonse. Malo enieniwo amakula ndikucheperachepera kwamitundu yamagulu.
