CAS 527-07-1 98% Industry Grade Powder Sodium Gluconate for Construction

Sodium gluconate can significantly delay the setting time of concrete. When the dosage is below 0.15%, the logarithm of the initial setting time is directly proportional to the dosage, that is, doubling the dosage delays the initial setting time by ten times, which extends the working time from a few hours to several days without compromising the strength. This is an important advantage especially on hot days and when the time required to place the concrete is long.
