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 application also has not been popularized in this respect, it is said in the papermaking wastewater from cellulose sulfonic acid sodium, the effect with sodium gluconate is not at all.Looking for ideal Sodium Salt Chemical Manufacturer & supplier ?
