Sodium gluconate feem ntau siv ib leeg, tab sis kuj tuaj yeem siv ua ke nrog lwm cov retarders xws li carbohydrate phosphates.Sodium gluconateyog crystalline hmoov. yog tsim nyob rau hauv kom raug thiab tswj tej yam kev mob. Cov tshuaj no yog tshuaj dawb huv thiab tsis-corrosive. Qhov zoo yog tas li. Qhov no feature guarantees txhim khu kev qha thiab rov tshwm sim nyob rau hauv nws daim ntawv thov. Qhov sib piv ntawm dej-rau-cement (W / C) tuaj yeem txo los ntawm kev ntxiv cov dej-txo tus neeg sawv cev rausodium gluconateraws li tus neeg sawv cev txo dej.

Cov dej thiab cov ntsiab lus tseem zoo ib yam thaum cov dej cov ntsiab lus txo qis, thiab qhov sib piv W / C tseem zoo ib yam. Lub sijhawm no,sodium gluconateua raws li cov cement reducer. Feem ntau, ob yam tseem ceeb rau kev ua vaj tse pob zeb: shrinkage thiab kub ntau lawm.Sodium Gluconate raws li RetarderSodium gluconatetuaj yeem cuam tshuam lub sijhawm pib thiab zaum kawg ntawm pob zeb. Thaum qhov ntau npaum li cas qis dua 0.15%, lub logarithm ntawm thawj zaug solidification lub sij hawm yog proportional rau cov compounding tus nqi, uas yog, tus nqi compounding yog ob npaug. Lub sij hawm rau qhov pib ntawm solidification yog ncua los ntawm qhov tseem ceeb ntawm 10, uas ua rau kev ua haujlwm txuas ntxiv los ntawm ob peb teev mus rau ob peb hnub yam tsis muaj kev cuam tshuam lub zog. Qhov no yog qhov txiaj ntsig tseem ceeb, tshwj xeeb tshaj yog nyob rau hnub kub thiab lub sijhawm ntev dua.
