Waukulu konkire gulu

Gulu la simenti zachokera muyezo waukulu atatu: mwa maikidwe, pa kachulukidwe ambiri, komanso ndi mtundu wa binder mu kusakaniza. Pakuti cholinga chake, nkhaniyi makamaka magawo kuchuluka subclasses. Mwachitsanzo, ena zikhalidwe muyenera apamwamba kutentha kukana, mu zina -. Impact kukana, etc. Pa mayesero onsewa, zikuchokera mulingo woyenera amasankhidwa kuti salola dongosolo la kugwa pa ntchito.

Nthawi zambiri, gulu zotsatirazi konkire anamanga pa cholinga:

- zipangizo cholinga chapadera (ntchito zinthu mkulu cheza mapangidwe acidic, ndi zina zotero);

- kwa msewu osakaniza, misewu, airfields;

- yachibadwa yowona (zikhale maziko, simenti, zosiyanasiyana nyumba analimbitsa simenti);

- zitsanzo hayidiroliki (ntchito kupanga zimbudzi, madamu, ngalande, etc.).

Gulu la kachulukidwe konkire Zimatengera mtundu wa aggregates coarse anadzetsa zikuchokera. Ngati osakaniza ndi pumice, tuff, ndi m'nyanjazi ena porous, mwina kulemera kwa tonnes 0.5 kuti 1.8 pa mita kiyubiki (concretes zing'onozing'ono, kuphatikizapo slag simenti, pumice konkire, kukodzedwa dongo). Pofuna kupeza zitsanzo makamaka lolemera (matani oposa 2.5 / Cu. Meter) anadzetsa konkire, filings zitsulo. zosakaniza amatigwiritsa ntchito polenga nyumba zozitetezera. Lolemera yowona (matani 1.8-2.5 / Cu. Meter) ndi lopangidwa diabase, lubwe kapena laimu.

Konkire gulu amatipatsanso osakaniza kopitilira muyeso-kuwala, monga simenti lokhala ndi mpweya wokwanira, lokhala ndi mpweya wokwanira simenti kapena foamed silicate. kulemera pa mita kiyubiki wa osachepera theka la tani. Konkire kalasi chifukwa cellularity chinawonjezeka ndi otsika matenthedwe madutsidwe, koma mphamvu otsika ndipo pa nthawi yomweyo. Choncho kwenikweni, iwo ntchito ngati akukumana zipangizo.

Gawo simenti ndi mtundu wa wothandizila kumangako kuposa kwambiri. Ambiri omwe si kuchuluka wothandizila lero ndi silicates ndi njira kuchiritsa mu autoclave ndi. Komanso infrequently anapeza zosakaniza zochokera galasi madzi, zigawo stekloschelochnyh kuti ndi zofunika mapangidwe kutentha zosagwira konkire.

Ambiri ndi zipangizo zochokera gypsum, amene kupanga ziwalo kokha, makoma mkati, ndi kupeza osakaniza zokutira madzi zosagwira. Komanso pali ankagwiritsa ntchito simenti yowona (monga simenti Portland), slag-zamchere (a mankhwala watsopano msika yomanga), polima zikuchokera.

Gawo ndi katundu konkire zofunika kuti aone magawo zofunika kusakaniza ndi mamangidwe m'tsogolo. Makamaka, nyimbo amenewa n'kopanda makhalidwe monga kuyenda (luso ikuyenda pansi pa madziwo yake), madzi kukana (a kuthamanga pa zomwe chitsanzo cha 0,15 mita ndi madzi), ndi umene uli wofunika kwambiri kwa Russian, chisanu. Mwachitsanzo, F1000 konkire chodetsa chingathe kupirira zikwi m'zinthu m'firiji pamtunda-m'firiji pamtunda, limene ndi lofunika kwambiri mu madera nyengo wosakhazikika, ndi nyemba F50 - 50 okha ngati m'zinthu.
