C40 High Strength Concrete (40N) is a pre-mixed, strong and hardwearing concrete. Manufactured from cement, 10mm coarse aggregate and specifically selected sand, it is formulated for exceptional performance where higher guaranteed strength is required.

Benefits:

• Conforms to BS 8500, for a CEM III/A+SR with additional attributes that enhance sulphate resistance
• Prevents damaging reactions to alkali silica.
• Prevents delayed ettringite formulation.
• Reduces the rate at which deleterious chemicals, such as chlorides, can penetrate the concrete
• 2-4 Hours Initial setting time

Applications:
C40 High Strength Concrete is ideal for a wide variety of building projects ranging from manholes, iron works and foundations to footing lampposts and road signs or any other work requiring a concrete with high compressive strength.

Technical Information
Strength will develop beyond the initial set time stated and has been assessed at 28 days. Setting and curing times will vary depending on water content used and ambient weather conditions. To assist the curing process, it is important that all cement-based materials are protected after placement, to avoid moisture loss, freezing and effects of hot and cold weather conditions.
