Boral Concrete Mix 20kg
Concrete is a proportioned blend of dry aggregate, graded sands and cement suitable for all general purpose concrete applications where a quality concrete is required.
Application / Use: Typical applications - general smaller concreting jobs like:
Garden edges etc.
Where a more structural concrete is required you may need to add neat cement to the premixed bag. As a guide, an addition of 1 kg to 1.5 kg per 20 kg bag of Blue Circle® GP can be used to achieve around 32 MPa concrete (under normal conditions). Concrete Mix Data Sheet
