What is the difference between grey General Purpose cement and Builders cement?
: General Purpose cement is a Portland cement with less than 5% Mineral Additions and Builders Cement is a Blended cement with approximately 60% Portland cement and 40% GGBFS (Ground Granulated Blast Furnace Slag). Builders cement is lighter in colour and develops early age strength more slowly than General Purpose cement, making it popular in bricklaying and rendering.
