Zambiri
Malinga ndi aggregate ufa lagawidwa zitsulo, sanali zitsulo kuvala zosagwira anaumitsa aggregate, amene amakhala ena tinthu gradation wa zitsulo mchere akaphatikiza kapena kwambiri kuvala zosagwira sanali chitsulo akaphatikiza ndi zina zapadera. Aggregates amasankhidwa molingana ndi mawonekedwe awo, masanjidwe ndi zinthu zabwino zakuthupi komanso zamakina.

Kuchuluka kwa ntchito
Amagwiritsidwa ntchito m'ma workshop a mafakitale, malo osungiramo katundu, masitolo akuluakulu, mafakitale olemera kwambiri, malo osungiramo magalimoto, malo osungiramo katundu, mabwalo ndi malo ena.
Makhalidwe amachitidwe
Imafalikira pamwamba pa konkire poyambira kukhazikika, ndipo itatha kuchiritsa kwathunthu, imapanga malo owundana komanso olimba kwambiri okhala ndi konkriti, yomwe imakhala yosasunthika, yosagwira ntchito, yosamva abrasion ndipo imakhala yolondola kwambiri komanso yopaka utoto wapamwamba kwambiri. Itha kumangidwa pamodzi ndi pansi konkire, kufupikitsa nthawi yogwira ntchito, ndipo palibe chifukwa chopangira matope osanjikiza.
Makhalidwe adongosolo
Kumanga kosavuta, kufalikira mwachindunji pa konkire yatsopano, kupulumutsa nthawi ndi ntchito, palibe chifukwa chopanga matope osanjikiza; kukana kwambiri abrasion, kuchepetsa fumbi, kusintha kukana, kusintha mafuta ndi kukana mafuta.
Ntchito yomanga
◇ Konkire pamwamba mankhwala: ntchito trowel makina okonzeka ndi chimbale kuti wogawana kuchotsa slurry wosanjikiza akuyandama pamwamba konkire;
◇Zinthu zoyatsira: falitsani 2/3 ya mulingo womwe watchulidwa wa zinthu zolimba zolimba zosagwira pansi molingana pamwamba pa konkire poyambira, kenako ndikupukuta ndi makina osalala otsika;
◇Kupakula molingana ndi kulinganiza zinthu zolimba zomwe sizingavale m'mbali mwa njira zopingasa ndi zazitali ndi chopalira cha 6-metres;
◇Kufalitsa kangapo kwa zipangizo: kufalitsa mofanana 1/3 ya mulingo wotchulidwa wa zinthu zolimba zosamva kuvala za mtundu (pamwamba pa zinthu zosamva kuvala zomwe zapukutidwa nthawi zambiri), ndikupukutanso pamwamba ndi makina osalala;
◇ Kupukuta pamwamba: molingana ndi kuumitsa kwa konkire, sinthani mbali ya tsamba pa makina opukutira, ndi kupukuta pamwamba kuti muwonetsetse kuti kutsetsereka ndi kusalala kwa pamwamba;
◇ Kukonza ndi kukulitsa malo oyambira: Pansi pa nthaka yolimba yosamva kuvala iyenera kusamalidwa pamwamba pasanathe maola 4 mpaka 6 ntchito yomangayo ikamalizidwa, kuti ateteze kusanduka nthunzi kofulumira kwa madzi padziko, komanso kuonetsetsa kuti zinthu zolimba zosagwira zikukula mokhazikika.
