Slurry: yabwino kufanana kwa osakaniza

yomanga Modern N'zovuta kulingalira popanda kugwiritsa ntchito zinthu monga simenti. Izi ndi yotsika mtengo zomangila, amene ali zingapo zochititsa ndi makhalidwe kuti ndizipange izo lonse.

Ntchito simenti

Simenti matope, chiwerengero cha amene zigawo anafotokozedwa ndi cholinga chake, ntchito zolinga zosiyanasiyana. Choyamba, ndi - zofunika kwambiri chigawo chimodzi cha konkire zochokera simenti; Kachiwiri, njerwa nthawi nachiyika pa simenti. Mwazina, popanda grout sindingakhoze kuchita izo pa cholinga cha pansi screed kapena makoma pulasitala.

zikuchokera grout

Muyenera simenti kwenikweni youma, mchenga, madzi ndi akaphatikiza chabwino kukonzekera simenti apamwamba. Anapangira zigawo zazikulu - mchenga ndi simenti - oscillate, zambiri mu osiyanasiyana 1: 2 1: 6. Malinga ndalama mmene metered a zosakaniza, yankho limakhala katundu wina. Mwachitsanzo, ngati yankho ndi kutsanulira kwambiri mchenga, mumasonyeza mphamvu yapamwamba, koma kutaya mu plasticity ndi ductility. Ngati simenti mu njira zambiri iye kupambana ductility, koma adzakhala kwambiri otsika mphamvu. Choncho, pamene slurry simenti amapangidwa, kuipa anasankha sing'anga - 1: 3 kapena 1: 4.

kupanga njira

Kuti knead njira khalidwe ndi zinthu zake ali osokonezeka mu mawonekedwe youma. M'pofunika kuti aliyense chigawo ali high quality, youma, wofumbutuka ndipo popanda apezeka. Apo ayi osakaniza ndi youma ndikoyenera kuti asiyanitse kapena pogaya apezeka. Tsopano, pamene osakaniza youma ndi wokonzeka, kuwonjezera madzi: kuthira pang'onopang'ono, oyambitsa msanga. Akukhulupirira kuti madzi okwanira kugwirizana pamene kusungunuka akufanana kirimu: ndiye kumanzere kwa mphindi 15, kenako angagwiritsidwe ntchito pa zolinga zina.

Komabe, pamene yankho wosanganiza simenti, kuipa mwina pang'ono zosiyanasiyana - mwachitsanzo, pamene laimu udzathiridwa mu izo. Mbali imeneyi osati kumawonjezera plasticity wa njira, komanso mphamvu yake. Standard chiŵerengero simenti: mchenga: laimu - 1: 5: 2.

zina

Kupereka yankho mbali iliyonse zina, zina Mankhwalawa amagwiritsidwa ntchito mu mtondo simenti. Izi plasticizers, zimakhudza modifiers, superplasticizers, kumatira ndi ikuthandizira wothandizila, ndi inki. Ntchito iliyonse zowonjezera ndi zoonekeratu plasticizers ndi modifiers amadza kusintha sayenda wa njira, kupanga simenti zotanuka ndi oyenera inayake opareshoni (mwachitsanzo, chindwi). Kumatira zofunika kuchepetsa mavuto obwera chifukwa cha chinyezi komanso madzi pa simenti ndi konkire; ikuthandizira wothandizila kuonjezera mphamvu. Koma pigment, izo wosachita ntchito ina m'malo zokongoletsa: izo ankangomva kuti athetse kudetsa mu mtundu wina. Pamene inu kuwonjezera zosafunika mu slurry, ndi kufanana ziyenela kuyan'anidwa mwandondomeko ngakhale wamkulu, chotero, si monga kusokoneza osakaniza palokha ndipo satero asokoneze mphamvu structural, kumene yankho amapangidwa.

Kusakaniza simenti, ganizirani mwamsanga anamvetsetsa: mu ola limodzi ndi theka, iye chidafundidwa ndi kutumphuka olimba. Choncho ndi bwino kusakaniza mu chakudya chochepa chabe pamaso ntchito.
