Konkire Kusakaniza

Lolemera konkire ntchito pamene khazikitsa makoma ndi simenti ndi nyumba ndi nyumba mafakitale. Opepuka simenti ndi zambiri ntchito kutchinjiriza (matenthedwe kutchinjiriza zipangizo).

Kodi mtundu wa kapangidwe ndi osakaniza konkire, simenti khalidwe zimatengera.
Konkire zigawo zikuluzikulu - madzi, filler, binder (dzina mwachizolowezi - simenti) zina. Mogwirizana ya binder ndi madzi amayambitsa zotsatira mankhwala, kupanga pawiri wina watsopano, kuyang'ana ngati mtanda yomata. Omanga amanenela mayeso a simenti, kapena simenti grout. Iwo anathira filler. Phala simenti ndi enaake anayesa malaya a filler particles ndi wawamanga (achilendo mafupa aumbike, amene kumathandiza mapindikidwe ndi shrinkage m'tsogolo). Pambuyo solidification lathunthu la konkire Kusakaniza amakhala olimba monolithic thanthwe.

Pa akaphatikiza (miyala wosweka, miyala, mchenga (kapena osakaniza Hud) chimachititsa pafupifupi 80% ya m'buku Komabe, chiwerengero akhoza kusinthidwa. Kuchokera kukhala gawo la konkire Kusakaniza zidzadalira zinthu zomwe zotsatira konkire pa (a molimba, kutentha zosagwira, opepuka, analimbitsa ., etc.) Komabe, si nthawi zonse zotheka kuti azidya kufanana enieni, makamaka ngati womanga - homegrown ankachita masewera.

Youma konkire Kusakaniza, wokonzeka kukhala mwina yabwino yothetsera. Izi mankhwala theka-yomalizidwa ndi mlingo wa simenti ndi akaphatikiza zigawo, kuchepetsedwa ndi madzi ndi analimbikitsa mwachindunji pantchitoyo. Youma konkire Kusakaniza akhoza kusungidwa kwa nthawi yaitali ndipo kokha ankadya akamavutika, popanda kusintha katundu, monga okonzeka mix.

Chimagwiritsidwa ntchito ndi youma yomanga zosakaniza. Izi zipangizo wothandiza ndi katundu apadera, advantageously ntchito liza (ufa utoto, zokutira textured, "madzi mapepala khoma" neri Al.). zosakaniza zosiyanasiyana (kwa mortars zomangamanga, zomatira kwa zadothi ndi matailosi, filler, kusalaza mankhwala, nyimbo sanation) Chili binder m'munsi. nyimbo iyi wokonzeka ali mokwanira kuchepetsedwa ndi madzi, ndi zina zabwino kwambiri "specialization" katundu kusinthidwa (plasticizing, wosasunthika kuti kusintha atakhala ndi oipa liwiro, zoletsa kuwuma, akusindikiza, madzi sangalowe, bactericidal, mpweya entraining, etc.).

Ndipo ngati posachedwapa ntchito liza osakaniza yowona (yeniyeni, ndi njira ya mchenga ndi simenti), koma tsopano ndi kusiya izo kasakaniza youma ntchito zigawo ndi centimeter ndi zambiri. Simenti - ndi binder mchere, ndi abwino kwa psinjika ndi molondola anatola mchenga izo "Mathandizo". Koma ngati yankho si nthawi zonse kupirira kupinda ndi kwamakokedwe nkhawa (makamaka ngati agwiritsidwa woonda wosanjikiza). Madzi posungira mphamvu ndi otsika kwambiri: madzi m'makala mu nthaka mofulumira ukuphwera ndi msanga, amene kumathandiza simenti hydration komaliza, chifukwa mu kungachepetse durability. Kumangidwa kwa zosakaniza youma zofooka izi pamenepo.

zosakaniza amenewa anawagawa gypsum, laimu, gypsum, miyala, simenti ndi simenti-laimu. Pongotayira akhale pansi miyala, ulusi (mchere, organic), tchipisi nsangalabwi, kumanga mchenga, zitsulo CHIKWANGWANI. Mafomu anafuna: chifukwa screeds ndi kudzikonda kukhazikika apansi, matailosi, zomangamanga, kupaka pulasitala. mankhwala Special ntchito:

- kulimbitsa patsinde pa;
- kusindikiza zimfundo;
- wolunjika yonyowa ndi mchere makoma;
- ndi kumatira;
- Kubwezeretsa ntchito (yokongola);
- anakonza mpandawo (putty zosakaniza).

Malinga mtundu wa ntchito ndipo anasankha zinthu zoyenera. Mankhwala onse ntchito zomangamanga, ndi konkire Kusakaniza limatenga 30-40% ndipo kasakaniza youma otsala 60-70%.
