A njira Konkire

Lero, kusowa kwa chuma, kaya malonda kapena mwachinsinsi, kuwonjezeka tsiku ndi tsiku. Ndipo chifukwa kuwonjezeka zofuna mu zomangira, gulu la monga, ndithudi, njira yowona, zina zosiyana auzidwa, kasakaniza youma, ndipo, ndithudi, njira.

Choncho, njira zomangamanga mwala angapereke kogwirizana yodalirika chibanthu kapena miyala atagona. Polima zomanga njira ndi pa chaubale pano ndi zosakaniza: madzi (makamaka osasankhidwa), simenti (pulasitala, simenti kapena laimu) ndi akaphatikiza (mchenga ndi zambiri gravelite). Childs mu zosakaniza ngati (kwa zomangamanga) Molingana ya laimu ndi mchenga wa 1: 3 kapena 1: 4. osakaniza amatchedwa kuti omanga Mtondo Gulu loyamba (RG I). Pamene apa osakaniza (mwachitsanzo, buku malita 80), kuwonjezera spades ochepa simenti, mu njira imeneyo kupeza chachiwiri osakaniza matope magulu - WG II. Kumanga nyumba chonyamulira kapena zapansi ntchito simenti-mchenga osakaniza, amene ntchito pomanga zambiri ena, ndipo chiwerengero cha mbali ya zigawo zikuluzikulu, limodzi unit wa mchenga: mayunitsi atatu cementitious mchitidwe kapena mmodzi wa mchenga: simenti mbali zisanu.

Iwo amagwiritsidwanso pulasitala. Iye wapangidwa wagawo imodzi ya laimu ndi mchenga magawo atatu - ndi ntchito panja. Monga mbali ya ntchito mkati, ndi malumikizanidwe a zigawo zikuluzikulu za zosiyanasiyana - wina unit wa laimu kuti mbali zisanu mchenga. Simenti pulasitala osakaniza si zochepa wotchuka kuposa simenti ndi mchenga zapansi, ndipo lili zikuchokera izi: chiwerengero cha mchenga ndi simenti - 1: 3. Tsopano zosiyanasiyana zina ntchito mu slurry simenti kuti Kuonjezera katundu makina ndi thupi. Ndi zonse gypsum zimabweretsa kumanga, izo amaundana crystallization ndondomeko wokha, popanda zina zilizonse.

Pamene tidzamvetsa cubage osakaniza ukuwonjezeka, chifukwa kupewa ichi, kuwonjezera mchenga pang'ono - gawo limodzi kuti madera awiri gypsum. Kuyambira chiŵerengero pakati pa kuchuluka kwa binder ndi filler mafuta wolemekezeka, ndi ochiritsira woonda matope zosakaniza. Mafuta - osakaniza kusintha, koma shrinkage ndithu pa kuchiritsa, ndipo ngati ntchito ndi nkhungu wosanjikiza - yokutidwa ndi ming'alu. Taphunzira ndi mlingo wochepa wa amafotokozera binder, ndipo, Tikawonetsetsa kupereka shrinkage pang'ono kwambiri, makamaka anayamikira pamene liners.

Ngati mukufuna kupereka mungakhale kukoma wapadera, ndiye kusiya kwanu pa akuda zomangamanga matope. Makamaka anasankhidwa kuti agwirizane akukumana zinthu zomangamanga osakaniza limachititsa kuti matabwa inconspicuous. Mtondo - chabwino tirigu kusakaniza amene anali bwinobwino vymeryat, ndipo imakhala ndi zinthu zochita kupanga, pang'ono madzi ndi tuzigawo twa ka filler. Izo ntchito zokongoletsa ntchito mkati ndi kunja, komanso kuika njerwa ndi mwala makoma. Pali mitundu njira: a kumatira - osakaniza simenti, imene anawonjezera Ceresit, ferric mankhwala enaake ndi sodium wochuluka aluminate; Ceresit - chisakanizo cha mtundu woyera, amene analandira chifukwa cha kaphatikizidwe amyl asidi, laimu, ndi amoniya; zomangamanga - chisakanizo cha simenti ndi laimu kapena simenti ndi dongo; Pulasitala - amaphatikizapo pulverized mchenga wokutira makoma mwangwiro yosalala; simenti - chisakanizo cha simenti, mchenga ndi madzi. Malinga mtundu wa njira chiŵerengero cha zinthu izi constituent angakhale osiyana. Tsopano opanga kugulitsa okonzeka zopangidwa chisakanizo cha mitundu yosiyanasiyana kuti anayala mu matumba 10, 15, 25 ndi 1000 kg. Osiyanasiyana zomangamanga njira ndi nambala ya ubwino pa simenti wamba:

1) The kusankha a mitundu; 2) solidifies pa maola angapo; 3) mtengo wotsika.
