Concrete super plasticizer-retarder

Description

Concrete super plasticizer-retarder

Concrete super plasticizer-retarder is a liquid additive based on polynaphthalene sulfonate. By increasing the efficiency and functionality of concrete, it also prevents the dehydration and separation of concrete aggregates.

A retarding superplasticizer for concrete is a type of chemical additive added to the concrete mix to both increase the fluidity and workability of the concrete and delay its setting time. This additive is typically used in projects requiring high-slump concrete with extended workability, such as large-scale pours, concrete casting in hot weather conditions, or in projects where concrete must be transported over long distances.

Features and Benefits of Concrete super plasticizer-retarder

• Increased Workability and Fluidity: This additive reduces friction between cement particles, increasing the fluidity of the concrete, which improves its workability.
• Reduced Water Demand: Retarding superplasticizers help reduce the amount of water needed in the concrete mix. This results in higher compressive strength and durability, making the final concrete more resilient and stable.
• Delayed Setting Time: These additives delay the initial setting time of concrete, which is particularly beneficial in hot weather or large-scale pours, preventing early cracking and rapid setting.
• Prevention of Slump Loss: These additives help maintain the concrete slump for a longer period, ensuring that the concrete retains its workability over time.
• Reduced Risk of Cracking and Shrinkage: By delaying the setting time, they help reduce stress from rapid drying, thus lowering the risk of cracking and shrinkage in the concrete.
