Simenti matope: kapangidwe ndi kupanga

The slurry simenti ndi chuma cholimba kwambiri, mwamsanga amakhazikitsa ndi ikamauma mu mlengalenga. Kuyambira limalowera pa kutentha madigiri 20 amapezeka pafupifupi atatu mwa anayi alionse ola. Yankho iyenera kugwiritsidwa ntchito palibe pasanafike ola limodzi pambuyo kukonzekera, kuyambira mwinamwake izo watha mphamvu. Pali zosiyanasiyana simenti - izo zimadalira ake. Njira okonzeka pa maziko awo ndi mphamvu osiyana compressive.

Kodi kupanga simenti matope

Kuti akonze simenti slurry ayenera kupeta mchenga ndi simenti kupyolera sieve ndi dzenje awiri a mamilimita 3. Zosakaniza ndi metered volumetric Mlingo ndi kusakaniza mpaka homogenous, ndipo ngati n'koyenera, sieved kachiwiri ndi osakaniza youma Chinawonjezeka madzi, mpaka makulidwe ankafuna.

Pakuti atagona chitoliro pamwamba pa denga wapangidwa zambiri zovuta matope ongokhala filler ndi zigawo ziwiri kumangako: mchenga, simenti ndi laimu putty. Pankhaniyi, muyenera kuwonjezera amodzi mbali simenti ndi zigawo zitatu laimu kuti mchenga magawo 15.

Slurry ntchito yokonzekera konkire kasakaniza. Anaika tchipisi atsopano konkire chivundikiro kapena makalipeti, madzi zochuluka wetting. Izi makamaka mwachita masiku asanu pambuyo kuwayika formwork, zolinga awa amagwiritsidwa ntchito polyethylene filimu kuti amalenga tingati ndi nthunzi.

Simenti matope: Kaonekedwe

Simenti matope pantchito yomanga zikhoza kugulidwa kapena payekhapayekha mwa kusakaniza mu magawanidwe ena a simenti ndi mchenga (kuchokera 1 mpaka 3, malingana amapanga 1 mpaka 6). Kumbukirani kuti pamanja kutulutsa njira osati yotopetsa, koma kuli kovuta wogawana kugawira zigawo zikuluzikulu zonse popanda chochitika yoyenera. Othandiza ntchito chosakanizira (makina kapena magetsi), sipangakhalenso onse anaigula lendi, anaitenga ku abwenzi.

wotchuka kwambiri ndi slurry simenti, imene ankagwiritsa ntchito chipangizo njerwa. Izi zikhoza ntchito mitundu iwiri ya njira - simenti ndi simenti-laimu. Ndi mtundu woyamba wa akuika katundu mwankhanza makoma ndi zinthu zina, pamene zikuchokera chachiwiri ntchito mitundu ina ya mapepala (zowalamulira mumtima makoma), ndipo anawonjezera mbali yaing'ono ya simenti.

Ngati matope ntchito m'nyengo yozizira, m'pofunika ntchito zina zoletsa kuwuma, amene salola kuzizira njira. Komabe, kutentha m'munsimu madigiri 20 Celsius simenti misa ndi bwino kuchita, monga zigawo izi sizikugwira ntchito. Pogwiritsa ntchito njira zina zosiyanasiyana kupatsidwa kusinthasintha zofunika ndi kuyenda. Kuonjezera akatswiri ductility njira wamba shampu anawonjezera kuthira theka-lita imodzi ya thunthu mu mita kiyubiki kulemera simenti. Mchere ndi monga zoletsa kuwuma zina, ngakhale malangizo ambiri, kutsanulira chisakhale asapanikize anthu efflorescence.

Simenti ndi simenti zokolola kutentha zosagwira zosakaniza amene ntchito yopanga nyumba monolithic foci ndi moto lotseguka, ndi firebox kapena ng'anjo zomangamanga atilakwira. Kuti akonze lawi kugonjetsedwa refractory zothetsera ntchito zigawo zikuluzikulu zotsatirazi ndi kufanana. Ngati yankho ku ntchito kulenga zotupa ndi moto lotseguka, kutenga chilemba simenti si chozama kupitirira 400. Kuti munthu gawo Chinawonjezeka magawo awiri a mwala wosweka, wopangidwa njerwa zofiira, magawo awiri a mchenga khwatsi kapena ku chabwino njerwa zofiira fireclay, ndi chachitatu mchenga chabwino. Kuti alenge firebox kutenga simenti chomwecho, wosweka mwala wa njerwa ndi firebricks mchenga wamba mu anapangira 1: 2: 2: 0,33.
