Retarders for Ready Mix Concrete

Set Time Retarding Admixtures

Set time retarders allow producers to extend set times according to specific project needs, providing flexibility and control in various construction scenarios. These admixtures offer several key benefits for concrete construction projects.

Key Benefits

Enhanced Workability

• Extends the working time of concrete, allowing for easier placement and finishing.

Reduced Thermal Cracking

• Minimises the risk of thermal cracking in mass concrete by controlling the heat of hydration.

Improved Surface Finish

• Ensures a smoother and more consistent surface finish.

Uniform Set Time

• Provides consistent set times across large pours, improving overall project quality.

Recommended Uses

Hot Weather Concreting

• Extends setting time in high temperatures, reducing the risk of premature setting.

Large Concrete Pours

• Ideal for large pours where extended workability is needed to prevent cold joints.

Complex Formworks

• Provides the necessary time to place and finish concrete in intricate formwork.
