Blue Circle Mastercrete Cement (25kg) is a multi-purpose enhanced performance cement developed by Tarmac for use in applications where strength, durability, and ease of work are essential. It is manufactured to comply with BS EN 197-1 and classified as CEM II/A-L 32,5R, making it suitable for all general-purpose construction requirements. However, what distinguishes Mastercrete from standard general-purpose cement is the addition of a proprietary air-entraining additive, which improves frost resistance, workability, and long-term strength development—making it ideal for more demanding building environments.
Performance & Workability
Blue Circle Mastercrete has excellent resistance to freeze/thaw cycles due to its air-entrainment characteristics, which create tiny air bubbles within the mix. These bubbles allow the hardened concrete to expand without cracking during frost, making it particularly suitable for external applications such as driveways, footpaths, garden walls, and shed bases. The cement also mixes more smoothly and evenly, offering a creamy texture that reduces labor fatigue during application.
