Ntchito ya konkriti admixtures:

Udindo wa zowonjezera za konkire zimasiyana ndi mtundu wa zowonjezera za konkire. Ntchito yayikulu ndikuwongolera kuchuluka kwa konkriti kofananira pomwe kumwa madzi pa kiyubiki mita konkire kapena kugwiritsa ntchito simenti sikusintha; pamene kugwiritsidwa ntchito kwa simenti sikunasinthe kapena kutsika kwa konkire sikunasinthe, kumwa madzi kumatha kuchepetsedwa, ndipo mphamvu ya konkire imapangidwanso bwino, ndipo kulimba kwa konkire kumakhala bwino; pamene mphamvu ya mapangidwe ndi kugwa kwa konkire kumakhalabe kosasintha, kugwiritsa ntchito simenti kungapulumutsidwe ndipo mtengo ukhoza kuchepetsedwa, etc. Wothandizira mphamvu oyambirira amawongolera mphamvu yoyambirira ya konkire ndipo amagwiritsidwa ntchito kwambiri pokonza zowonongeka ndi konkire yomanga yozizira; chotsitsa madzi chimakhala ndi mphamvu yochepetsera madzi ndi kulimbikitsa pamene kusunga konkire kosasinthika; mpweya etraining wothandizila makamaka amachepetsa madzi tsankho chifukwa thovu kwaiye pa ndondomeko kusakaniza konkire ndi bwino workability konkire; wobwezeretsa amatha kuchedwetsa nthawi yoyika konkire, ndipo imakhala ndi zotsatira zochepetsera komanso zochepetsera madzi. Amagwiritsidwa ntchito makamaka pa konkire yamagetsi akuluakulu, konkire yomangidwa pansi pa nyengo yotentha, kapena konkire yonyamula mtunda wautali.

Kuwunika kwa mphamvu ya admixture water reducer pa ntchito ya konkire:

Konkire admixture madzi reducer makamaka wopangidwa surfactants. Chowonjezera ichi ndi cha anionic surfactants. Kwenikweni, konkriti wothandizila madzi amchere samagwira ntchito ndi simenti. Zotsatira zake pa konkire zimawonekera makamaka mu pulasitiki ya konkire yatsopano. Plasticization ndi wetting, adsorption, kubalalitsidwa ndi mafuta kwenikweni.

The adsorption, dispersion, lubrication and wetting effect of admixture water reducer zimapangitsa kuti zikhale zosavuta kusakaniza konkire mofanana ndi madzi ochepa chabe, kuti ntchito ya konkire yatsopano ikhale yabwino. Uku ndiye kupangika kwa pulasitiki kwa chotsitsa madzi admixture pa konkire yatsopano.
