Sodium gluconate Nthawi zambiri amagwiritsidwa ntchito pawokha, koma atha kugwiritsidwanso ntchito limodzi ndi zoletsa zina monga ma carbohydrate phosphates.Sodium gluconatendi ufa wa crystalline.amapangidwa pansi pamikhalidwe yofotokozedwa bwino komanso yoyendetsedwa bwino.Pagululi ndi loyera komanso losawononga.Ubwino ndi wokhazikika.Izi zimatsimikizira zotsatira zodalirika komanso zobwerezabwereza pakugwiritsa ntchito kwake.Madzi-to-simenti ratio (W/C) akhoza kuchepetsedwa powonjezera madzi kuchepetsasodium gluconatemonga wothandizira kuchepetsa madzi.
Madzi ndi zomwe zilimo zimakhala zofanana pamene madzi akuchepa, ndipo chiŵerengero cha W / C chimakhalabe chimodzimodzi.Pakadali pano,sodium gluconateamagwira ntchito ngati chochepetsera simenti.Mwambiri, mbali ziwiri ndizofunikira pakuchita konkriti: kuchepa ndi kupanga kutentha.Sodium Gluconate ngati RetarderSodium gluconateimatha kuchedwetsa nthawi yoyamba komanso yomaliza ya konkire.Pamene mlingo uli pansi pa 0.15%, logarithm ya nthawi yokhazikika yokhazikika imakhala yofanana ndi kuchuluka kwa kuphatikizika, ndiko kuti, kuchuluka kwake kumawirikiza kawiri.Nthawi yoyambira kulimbitsa imachedwa ndi gawo la 10, zomwe zimathandiza kuti ntchito ipitirire kuchokera ku maola angapo mpaka masiku angapo popanda kusokoneza mphamvu.Uwu ndi mwayi wofunikira, makamaka pamasiku otentha komanso nthawi yayitali.
Monga wachinyamata,sodium gluconatewakhala akugwiritsidwa ntchito kwambiri mu konkriti.Kafukufuku wochepa ndi machitidwe a uinjiniya awonetsa kuti: kugwiritsa ntchito pamodzisodium gluconatendi superplasticizer imatha kusintha kuchuluka kwa madzi, kuchepetsa kutsika, komanso kukonza njira yochepetsera madzi.Kusinthasintha kwa simenti ndizodziwikiratu.Komabe, chifukwa chogwiritsa ntchito molakwika muumisiri, zidzapangitsa kuti pakhale kusakhazikika kwa konkire, ndipo zochitika zapamwamba zaumisiri zidzakakamizika mochedwa, zomwe zimabweretsa kutayika kwakukulu kwachuma.sodium gluconatemonga chowonjezera cha konkire, zochitika zenizeni, monga chilengedwe, nyengo, mlingo wa konkire, ndi zina zotero, ziyenera kugwiritsidwa ntchito ngati zofotokozera, kuti zitsimikizire phindu lalikulu.
