Opanga zochepetsera madzi amapanga zochepetsera madzi, ndipo akagulitsa zochepetsera madzi, amaphatikizanso zosakaniza zochepetsera madzi. Chiŵerengero cha madzi-simenti ndi chiŵerengero chosakaniza konkire chimakhudza kugwiritsa ntchitopolycarboxylate superplasticizer. Polycarboxylate superplasticizersamakhudzidwa kwambiri ndi madzi a konkire. Pokonzekera C50 konkire mu ntchito, kapangidwe koyamba madzi-simenti chiŵerengero anali 0.34%. Mayesowa adapeza kuti madziwo anali ochepa, kotero kuti chiŵerengero cha Madzi-simenti chinasinthidwa kukhala 0.35%, ndipo kumwa madzi pa kiyubiki mita kunawonjezeka ndi ma kilogalamu angapo.
Ngakhale kuti kugwa kwawonjezeka, palinso kuchuluka kwa seepage komanso ngakhale tsankho, zomwe zimakhudza kufanana kwa konkire. Kuonjezerapo pang'ono posungira madzi kwachititsa kuti pakhale vuto lalikulu pa zomangamanga. Chiŵerengero cha mchenga wa konkire chimakhudzanso kugwiritsa ntchito poly Carboxylate superplasticizer. Mukamagwiritsa ntchito zinthu zomwe zimagwiritsidwa ntchito kwambiri zochepetsera madzi, chiŵerengero cha mchenga chikhoza kuwonjezeka moyenerera ndipo madzi a konkire amatha kusintha.
Mukasakaniza ndipolycarboxylate superplasticizer, chiŵerengero cha mchenga ndi chachikulu ndipo madzi a konkire ndi osauka. The mankhwala unyolo wapolycarboxylate superplasticizermitundu yochepetsera madzi yokhala ndi mpweya wokhala ndi ma carboxyl adsorption gene ndipo imakhala ndi nthambi zambiri. Unyolo wam'mbali wa polyether umapereka cholepheretsa steric, pomwe ma polyether ali ndi zinthu zopumira.
Chifukwa cha kusiyana kwa njira zopangira komanso kusiyana kwa kulemera kwa maselo muzinthu zopangira zomwe zimagwiritsidwa ntchito ndi opanga osiyanasiyana, palinso kusiyana kwakukulu mu mphamvu yolowera mpweya. Pakati pa zinthu zingapo zapoly Carboxylate superplasticizer zomwe tidayesa, kutsika kwa magazi kunali 3% yokha, kukwezeka kunali 6%, ndipo zinthu zina zidafika 8%.
Choncho, pogwiritsira ntchito mankhwala ochepetsetsa kwambiri a madzi, m'pofunika kuyesa musanagwiritse ntchito, kenaka kusakaniza molingana ndi momwe polojekiti ikuyendera.
