Isitshalo se-sement-sand. Ukwakhiwa nokulungiselela

Enye yezingxenye eziyisisekelo zomxube wokufaka izindawo zokubeka, noma izixazululo zekhonkrithi, isamente. I-samente manje ibhekwa njengento ethandwa kakhulu, ngoba inezikhwebu ezanele ne-plasticity.

Kumele ngithi lapho kwenziwa ukwakhiwa noma ukukhiqizwa kwemisebenzi yokukhanda nokwakhiwa, cishe ungalokothi usebenzise isamende ngendlela ehlanzekile. Lokhu kuyabiza, futhi isamende ehlanzekile eqinisiwe yithemba kakhulu, ngakho-ke le brickwork kuso ayinamandla. Ngakho-ke, kuyisiko ukusebenzisa isitshalo se-samente kumasayithi wokwakha. Futhi isilinganiso sezingxenye kuxhomeke enjongweni leyo ingxube ezosetshenziswa kuyo.

Ngamanye amazwi, uma udinga ukubeka izitini, khona-ke udinga ukusebenzisa umhlabathi wesamente wensimbi ohlobo olufanayo. Ukufaka izindawo zokubeka - olunye uhlobo, njll. Kumele ngithi izixazululo eziyinkimbinkimbi nezisetshenziswayo zakhiwa ekwakhiweni. Nakuba zihlukile, ngaphezu kwakho konke, inani lezingxenye ezisetshenzisiwe. Yebo. Uma isisombululo esilula singalungiselelwa kalula emanzini, ingxenye ethile yamakhemikhali nesihlabathi, izisombululo eziyinkimbinkimbi zenziwe izithako ezingaphezulu.

I-Brick laying, njengomthetho, ifakwa kwi-lime noma eyinkimbinkimbi yodaka lomhlabathi. Isitshalo semithi yisisombululo eshibhile futhi esikahle, ngakho-ke sisetshenziswa kakhulu. Kodwa-ke, lapha kufanele kuqashelwe ukuthi amandla alo kwezinye izimo ashiya okuningi okudingekayo, ngakho-ke ukuzakhela okuqinile ukusebenzisa leli fomu akukhuthazwa. Ngalesi sizathu, umhlabathi wesamente-m100 noma i-m150 ufaneleka kakhulu.

I-M100 yiyona ethandwa kakhulu phakathi kwazo zonke ezinye izingxube zalolu hlobo futhi ngokuvamile isetshenziselwa ukwakhiwa kwezindlu nasemsebenzini wokulungisa nokwakhiwa. Ingasetshenziselwa ukubetha, ukubeka izikhonkwane zokukhonkolo, izikhonkwane ze-slag kanye ne-foam, kanye nokufakwa kwezingcingo kwizisekelo zokukhonkolo.

Okuthandwa kakhulu yi-sement-sand mortar m150 . Iqukethe i-filler emihle, futhi ngokuqondene nelitshe elichotshoziwe noma izingxenyana ezinkulu ze-filler, azikho kuwo nhlobo. Izingxenye eziyinhloko zalesi sixazululo zingumhlabathi nesamente, kanti isamente ithathwa kancane kakhulu ekukhiqizeni ibanga lokukhonkolo m150. Ngokuvamile ibizwa ngokuthi udoti, usimende lwamatshe, udoti lwamapulangwe. Futhi kulokhu okulandelayo ingxenye ethile ye-lime isenezelwe ekubunjweni kwayo. Kwezinye izimo, ubumba bangase bengezwe esitsheni se-samente ukuze sikwazi ukuqina.

Izindlela zokwakha ezikhethekile zakhiwe ukuthi zithole isilinganiso esifanele sentshonalanga nesamente ekulungiseleleni imixube enjalo. Kumele ngithi amandla esixazululo, ngenxa yokwengezwa kwesihlabathi kuwo, akhula, kodwa ngesikhathi esifanayo ipulasitiki yayo iyancipha. Ngokuvamile, izingxenye ezingu-3 zesanti kanye nengxenye eyodwa yesimende zengezwe kwisixazululo. Isixazululo esinjalo kubhekwa njengesiqalo futhi sisetshenziswa kaningi.

Ukuze wenze ingxube yekhwalithi ephezulu, kufanele uqale ukuxuba izingxenye ezomile, kepha uma amanzi efaka, kufanele ube ngezingxenye ezincane engxenyeni eyomile. Engeza amanzi kuze kutholakale ukuvumelana okunamandla. Ngemuva kokuthola ubuningi obunjalo, ikhambi kufanele lishiywe kuze kube yimaminithi angu-15, bese uxoxisana kahle. Empeleni, i-samente egcwaliswe ngamanzi ingabamba ihora noma amabili, isixazululo esikhulu semikhawulo akumele sikulungele ukuze sigweme ukusetshenziswa kwamathenda.

Ezimweni zomswakama ophezulu noma isithwathwa, izithasiselo ezikhethekile zivame ukungena emhlabathini wesitheni samasenti. Kodwa-ke, kuyasiza ukunaka impilo yeshalafu samakhemikhali, ukuze kungalimazi amandla omboni.
