Product Overview
Sodium gluconate is a white or light yellow crystalline powder, soluble in water, slightly soluble in alcohol, insoluble in ether. Sodium gluconate as a retarding agent can be widely used in concrete. Adding a certain amount of sodium gluconate to concrete can increase the retarding effect of concrete and delay the initial and final setting time of concrete.
Scope of application: 1, suitable for construction of concrete and large volume concrete under hot temperature conditions, cast-in-place piles, etc. 2, suitable for slip-form construction concrete, pumping concrete, fly ash concrete, etc.; 3, can be configured with C15-C45 grade concrete.
Product Model SL-I SG-F
Performance characteristics: 1, this product is non-toxic, non-combustible, stable form, no corrosion on the steel bar; 2. It has the effect of reducing water, improving the late strength of concrete or increasing the fluidity to save the amount of cement; 3, in the summer construction and continuous pouring of concrete can prevent cracks; 4, reduce the hydration heat of concrete and delay the time when the temperature peak appears, reduce the cracking caused by the temperature difference inside and outside. 5, convenient construction and long-distance transportation.
6, recommended dosage: 7, test to determine the best dosage
method: 1, according to the engineering requirements, adjust the dosage after the test; 2. Generally, it is added to the mixer with mixing water at the same time. The plasticizing effect is the best if the delay is added or the concrete is added and stirred slightly before pouring. 3, in order to ensure the best use of the effect, it is recommended that the user in the first use of this product or in the project before the replacement of cement varieties, should be based on the specific situation of the project, by trial mixing test to determine the best dosage and mixing method.
Packaging and storage: 1, powder products for 25kg/ bag, should prevent damage to the packaging moisture, 2, should be stored in a cool and dry place, avoid direct sunlight. 3, the shelf life of this product is 2 years, expired should be determined by the experiment.
