Blue Circle® Builders Cement is a versatile alternative to Blue Circle® General Purpose (GP) Cement and can replace it in most applications. Some adjustments to the mix design may be necessary depending on the application. It is specifically produced for use in areas such as brick work and block work masonry, construction mortars, solid cement rendering, bedding and pointing of roof tiles etc. Strength at an early age may be slightly lower than GP cements but with appropriate curing, there are advantages in higher later age strengths
