Kugawika kwa Adretet Admenties:
1. Admixtaxtures pokonza zopanga zamitundu yazosankhidwa bwino, kuphatikizapo madzi osiyanasiyana amadzi, okonda mpweya ndi kupopera mpweya.
2. Admixtaxures posintha nthawi ndi kuumitsa katundu wa konkriti, kuphatikizapo ogulitsa, othandizira oyambirira ndi othamanga.
3.
4. Admixtaxures kukonza zinthu zina za konkriti, kuphatikizapo othandizira a mpweya, othandizira okumba, anifare hers, olojekiti, odzola, etcroousming othandizira, etc.
Kuchepetsa Madzi:
Madzi ochepetsa madzi amatanthauza kuphatikizika komwe kumatha kupitiriza kugwiritsidwa ntchito kwa konkriti kosasinthika ndikuchepetsa kwambiri kusakaniza kwamadzi kuphatikizika. Popeza kuchepetsera madzi kumawonjezeredwa kunyumba yosakanikirana, ngati madziwo amasinthidwa, kugwiritsidwa ntchito kwake kumatha kukhala bwino kwambiri, kotero madzi kuchepetsa mankhwalawa amatchedwanso pulasitiki.
1. Makina ogwiritsira ntchito madzi amachepetsa wothandizirayo pambuyo pa simenti ikasakanikirana ndi madzi, miyeso ya simenti imakokana wina ndi mnzake ndikupanga mabomu ambiri m'madzi. Mu kapangidwe ka nkhosayo, madzi ambiri osakanikirana amakulungidwa, kuti madzi awa sangasewere gawo lowonjezera madzi osokoneza. Pamene wothandizira madzi amawonjezeredwa, wothandizira madzi amatha kulowetsa madzi abwino awa ndikumasula madzi aulere omwe amalowa m'madzi aulere, poyankha madzi osakanikirana. Pakadali pano, ngati kugwirira ntchito koyambirira kwa koyambirira kumafunikirabe kusasinthika, madzi osakanikirana amatha kuchepetsedwa kwambiri ndipo madzi kuchepetsa mphamvu zitha kutheka, motero amatchedwa mankhwala amadzi.
Ngati mphamvu sizikusintha, kuchuluka kwa simenti kumachepetsedwa kwinaku akuchepetsa madzi kuti akwaniritse cholinga chopulumutsa simenti.
2. Maukadaulo ndi azachuma ogwiritsa ntchito madzi ochepetsa madzi ali ndi luso lotsatira
a. Kuchuluka kwa madzi osakanikirana kumatha kuchepetsedwa ndi 5 ~ 25% kapena kupitirira pomwe kugwirira ntchito sinasinthe ndipo kuchuluka kwa simenti sikufupikitsidwa. Popeza kuchuluka kwa mmadzi kumachepetsedwa ndikuchepetsa kuchuluka kwa madzi osakanikirana, mphamvu zitha kuchuluka ndi 15-20%, makamaka mphamvu yoyambirira imatha kusintha kwambiri.
b. Pansi pa kukhala osakanikirana choyambirira, chosakanikirana cha osakaniza chimatha kuwonjezeka kwambiri (100 ~ 200mm akhoza kuchuluka), kupangitsa kukhala koyenera pomanga ndikukwaniritsa zofuna kupondaponda zomanga ku konkire.
c. Ngati mphamvu ndi kugwirira ntchito zimasungidwa, simenti ikhoza kupulumutsidwa ndi 10 ~ 20%.
d. Chifukwa chakuchepetsa kuchuluka kwa madzi osakanikirana, magazi ndi tsankho la osakaniza zimatha kusintha, zomwe zingakuyendere ku chisanu ndi chosautsika kwa konkriti. Chifukwa chake, kulimba kwa konkriti komwe kumagwiritsidwa ntchito bwino.
3. Pakadali pano zimagwiritsidwa ntchito poyerekeza ndi madzi
Mankhwala ochepetsa madzi makamaka amaphatikizapo mndandanda wa Linsin, Nambolealene mndandanda, zozizwitsa, zimapangitsa kuti madzi azikhala oyendetsa, obwezeretsanso molingana ndi ntchito yayikulu. Madzi kuchepetsa mankhwala, madzi osungirako mpweya, etc.
