Kulemera enieni konkire zimadalira mtundu wake

An mwala yokumba amene amapangidwa mwa kusakaniza madzi, simenti ndi aggregates (miyala, mchenga kapena miyala), ndi kupititsa patsogolo solidification awo amatchedwa konkire.

Monga chuma nyumba anayamba kugwiritsidwa ntchito kalelo zikuchokera konkire kenako ankasiyana ndinasintha kuchokera pano. Panali nthawi imene anaimitsidwa pa nthawi ya ntchito, koma m'zaka za m'ma XIX kupangidwa binders latsopano hayidiroliki, monga Mwachitsanzo, Portland simenti, ndi konkire kukonzanso zinatchuka kumangako. Mu 60 ntchentche za m'ma XIX. Izo zinali bwino simenti luso kupanga, mtundu mphamvu kuchuluka ndipo ntchito ngati binder chachikulu konkire. Panthawi mankhwala - mmodzi wa zipangizo zofunika kwambiri ntchito pafupifupi m'madera onse a zomangamanga ano.

kuzindikira zimenezi, iye analandira zikomo makhalidwe zotsatirazi:

• zosiyanasiyana katundu anapeza chifukwa chakuti khalidwe la ntchito zipangizo mwala ndi binders ndi zosiyanasiyana physicochemical ndi processing mawotchi;
• kuwachepetsera ntchito ndi konkire Kusakaniza, amene ali kusinthasintha mkulu ndipo amalola kupanga zosiyanasiyana akalumikidzidwa ndi makulidwe a cholimba, nyumba yapamwamba nyumba;
• zotheka wonse mechanize ndondomeko ya ntchito ndi konkire;
• chuma, ngati buku ake ndi 80-90% tichipeza mwala limaphatikiza kupanga m'deralo.

Kupanga mkulu khalidwe konkire Kusakaniza ndi zotheka ndi chidziwitso cha luso, kusankha zipangizo luso zina khalidwe ndi luso kuwerengera chiŵerengero awo, kupeza njira makongoletsedwe, zisindikizo ndi kusakaniza modes.

Kumangira nyumba zosiyanasiyana zomangamanga ntchito mitundu yosiyanasiyana ya yowona (mu malingana ntchito). Pali zinthu zingapo zofunika, amene ali m'magulu zakuthupi: kulemera zenizeni za simenti ndi mphamvu, mtundu wa binder, cholinga ndi chisanu. Gulu lalikulu amapangidwa pa kulemera buku. Chotero iye, concretes kwambiri kuwala, kuwala, olemera ndi owonjezera lolemera.

1. Mu choyamba - ambiri a a sing'anga ndi yaing'ono maselo pafupifupi 1-1.5 mm kukula, kotero iwonso amatchedwa ma. Kulemera yeniyeni voliyumu konkire mita kiyubiki 1 500 makilogalamu. Childs, mtundu uwu ntchito monga kutentha zokutira zitsulo wosanjikiza.

2. Kuwala. mtundu Izi zikuphatikizapo anthu amene monga placeholder ntchito zipangizo yosavuta opepuka - kukodzedwa dongo, tuff, rakushnik, kapena china osagwiritsa ntchito fillers uliwonse, ndi kuchita thobvu wothandizira anawonjezera -. konkire, lokhala ndi mpweya wokwanira konkire ndi ena The gawo la buku konkire pa mita kiyubiki - 500-1800 kg. Mbali yaikulu ya kapangidwe kake amatenga mchenga - mpaka makilogalamu 600. zinthu kawirikawiri amagwiritsidwa ntchito pa ulimi wa nyumba zingatipunthwitse.

3. Monga mbali ya konkire katundu ndi aggregates krupnofraktsionnye lolemera - miyala ndi mwala wosweka. Wina mita kiyubiki za izo akulemera pafupifupi 1800-2500 kg. chophimba Izi zikusonyeza makilogalamu 1150-1300 ya miyala kapena mwala wosweka, mchenga 600-750 makilogalamu, 250-450 makilogalamu a simenti, malita 150-200 madzi. Lolemera mwala ndi tingachipeze powerenga ndi ntchito m'madera ambiri a zomangamanga.

4. concretes Makamaka wolemera ndi lopangidwa barite, magnetite, ndi mitundu ina ya zitsulo zotha. The yeniyeni kulemera kwa konkire buku la mita kiyubiki 1 zingakhale za 2500 kuti makilogalamu 3000. Mbali yaikulu ambiri misa ndi coarse akaphatikiza. Mtundu konkire ntchito kwenikweni kupanga nyumba zoteteza AEC.

Kuwerengetsera mita kiyubiki konkire, sitiyenera kuiwala kuti zigawo zake mwina yokoka osiyana yeniyeni. Mwachitsanzo, kagawo kakang'ono ka akaphatikiza coarse molimbika ndi mchenga dzenje ndi mosavuta kuposa mtsinje.
