SODIUM GLUCONATE C6H11NaO7 

Delay the initial and final solidification time of concrete, such as adding 0.15% sodium gluconate, solid initial setting time of concrete can be extended more than 10 times, and the plastic concrete is time extend from a few hours to a few days, without affecting its prison.Plasticity and delay the initial solidification time is a very important problem in the concrete operation, such as construction in high temperature season and large engineering work, delay the initial solidification time is a difficult problem, sodium gluconate can be successfully solves the problem.Other high temperature cementing Wells is difficult, after adding the sodium gluconate concrete under 170 ℃ high temperature, the plastic within a few hours, so it can successfully solve the above problems.So sodium gluconate as cement admixture have been extensively applied in the important construction engineering in foreign countries, such as a large number of bridge engineering in the Middle East.But our domestic a…
