The kachulukidwe konkire

Konkire ndi yokumba zomangila, kuchipeza mwa kuumba ndi wotsatira solidification rationally asankhidwa ndi osakaniza ting'onoting'ono basi. Amakhala ndi simenti kapena zipangizo kumangako, komanso aggregates chabwino ndi coarse ndi Kuwonjezera wa madzi. Nthawi zina, kumene wapadera ayenera kachulukidwe konkire Mwachitsanzo, phula luso konkire, madzi si anawonjezera, ndi ntchito zina zapadera.

ubwino waukulu ndi wochezeka, komanso kupezeka kwa yaikulu zopangira m'munsi. N'zotheka kuziyika izo mu zikhalidwe zosiyana opaleshoni. Iwo angatchedwe zakuthupi mosalekeza kuti ntchito kwambiri mu madera onse ndi kumabungwe a zomangamanga. Ndi mankhwala ndi kutentha zosagwira, phokoso-zogwira mtima ndi chiyani makhalidwe cheza nyukiliya.

Kusakaniza mchenga, simenti, madzi ndi miyala zimathandiza kupeza kachulukidwe Napempha kwa konkire. Chiŵerengero kudzadalira mnyontho ya mchenga ndi miyala, simenti kalasi ndi ting'onoting'ono. Nthawi zina, zimakhudza kuchuluka ndi zikuchokera zina :. Water mankhwala othamangitsa, plasticizers, etc. Mwachitsanzo, kuti osalimba a M200 konkire, ntchito simenti kalasi 400.

Mmodzi zofunika khalidwe la nkhaniyi ndi madzi simenti chiŵerengero. Pali kudalira mwachindunji madzi / simenti. Ndiko kuti, m'munsi chiŵerengero, mphamvu konkire. zakuthupi A ndi osalimba a 200, ali misa ndithu (kuti zake yekha "ukonde"). Akafika 2400 makilogalamu / M3. Ichi ndi zazikulu konkire nyumba katundu zobala, mizati, crossbars, etc. Kwambiri ping'ono wa madzi osalimba a simenti ndi mkulu ndipo ali ndi otsika plasticity. Izo ntchito maziko a zida, akhungu malo ozungulira nyumba ndi zina zotero.

Pali wina kulakwitsa kuti nthawi zambiri pamene kusakaniza njira. makampani Chotsimikizika kawirikawiri anawonjezera kuti yambiri ya madzi, zimene zimachititsa osalimba a konkire ndi kuonjezera sayenda ake. Kubwerera ku kumachepetsa kwambiri mphamvu yake.

Konkire ali gulu chake, chimene cholinga, mitundu ya fillers ndi binders, zinthu kuchiritsa, ndi matabwa ake. Mwa maikidwe, mukhoza kusankha yachibadwa (kwa nyumba zaboma ndi mafakitale) ndi wapadera (njira yomanga, kutchinjiriza ikukhudzana hydro ndi zokongoletsa ntchito) konkire.

Ndi mtundu wa binder ndi pulasitala, silicate, simenti shlakoshchelochnyh (phula, kapena plasto- polimernbeton). Mitundu ya aggregates ake komanso ndife osiyana: porous, wandiweyani mosabisa, ndipo nkhani zake - othina, mafuta ndi chofunika. Komanso, matabwa ake akhoza kukhala yowona wandiweyani, porous, uchi ndi pore lalikulu. zinthu kuchiritsa akutsatira: achilengedwe, nthunzi kuchiritsa opanikizika mumlengalenga kapena autoclave.

The chizindikiro chachikulu makhalidwe konkire - ndi mphamvu compressive. Iwo imalongosola kalasi konkire. Mwachitsanzo, osalimba a konkire B25. Izi zikutanthauza kuti 95% ya kalasi tipirire kufinya 25 MPa. Ndiko kuti, kalata "B" ndi zithunzi amasonyeza kuthamanga chimene chingathe kupirira konkire mu megapascals. Kuwerengetsera chizindikiro cha mphamvu, izo chofunika kuganizira zinthu zolimbana compressive mphamvu. Ndi abwino kwa konkire kachulukidwe B25. Age konkire mawu a kalasi ake, kudzayesedwa mphamvu compressive ndi ofananira nkhawa, amene anatumizidwa wina siteji kamangidwe. Kodi n'komwe njira zotheka ntchito yomanga ndi kapangidwe katundu pa kapangidwe ndi zikhalidwe za oipa konkire.

osalimba a konkire 25 abwino slabs pansi, maziko olimba, mbale mabeseni. Izi kaŵirikaŵiri ntchito mfundo zolinga zimenezi. Komanso, kugwiritsa ntchito omanga zakuthupi ndi nyumba zina udindo kopita. kachulukidwe konkire 25 zipangitsa zabwino kwambiri wa nyumba iyo kusasanyiwa, anapereka kumene kuti mankhwala anagula ndi kwathunthu mogwirizana ndi specifications lofalitsidwa.
