CONCRETE ADDITIVES
LIGNOSULFONATES
Lignosulfonates are used as a plasticizer additive in the concrete industry, it allows to improve its workability and significantly reduce the amount of mixing water, which causes a greater and faster mechanical resistance of the set product, which is also less permeable, more homogeneous and aesthethic. Sodium and Calcium lignosulfonates are generally used for this application.
Some of the benefits are:
- They provide greater strength and durability to concrete.
- Reduction of water, increasing the fluidity of the dough, improving the rheological properties.
- Retardant effects in concrete admixture.
Sodium gluconate as concrete additive
The sodium gluconate is used as an additive for concrete formulation.
Some of its benefits are:
- It works as a retardant in the setting process.
- It is an agent that disperses and moistens the concrete ingredients, which provides greater stability, allows it to have greater adherence to metal reinforcements and reduces corrosion.
Some of the benefits are:
- They provide greater strength and durability to concrete.
- Reduction of water, increasing the fluidity of the dough, improving the rheological properties.
- Retardant effects in concrete admixture.
