GB 50

A Smarter Blend for Cement & Construction Applications

Greencem GB 50 is a Green Composite Cement Additive developed from a carefully proportioned blend of superfine ground Fly Ash, Ground Granulated Blast Furnace Slag (GGBS), Limestone and strength activators.

GB 50 is designed to provide a consistent and effective supplementary cementitious material for cement and construction applications. Its controlled formulation combines the beneficial properties of Fly Ash and GGBS to support improved performance and efficient utilization of supplementary cementitious materials.

In Greencem, our focus is on

Why GB 50?

GB 50 has been developed to provide a practical and cost-effective solution for applications where supplementary cementitious materials can be used alongside OPC 53.

Enhanced Strength

GB 50 can contribute to improved early and final strength in suitable applications when used with the appropriate mix design.

Cement Replacement

GB 50 can be used as a partial replacement for OPC 53. A 50:50 GB 50 to OPC 53 mix ratio recommended as a starting point, subject to application requirements and performance testing.

Smooth Finish

In Fly Ash brick applications, GB 50 can contribute to a smoother and more uniform finished surface.

Consistent Formulation

A controlled blend of Fly Ash, GGBS, Limestone and strength activators provides a consistent product for regular application.

Applications

Fly Ash Brick Manufacturing

GB 50 is suitable for Fly Ash brick manufacturing and has been supplied in bulk to brick manufacturing units.
Customers have reported benefits including improved early and final strength, reduced OPC consumption, smoother brick finish and improved cost efficiency.

Plastering & Brickwork

GB 50 can also be used by civil contractors for plastering and brickwork applications. Its formulation is designed to provide a practical supplementary cementitious solution for construction activities.

Recommended Mix Ratio

GB 50 + OPC 53

Technical Specifications

Composite Cement Compatibility

When blended with OPC 53 at the appropriate proportions, GB 50 is developed for composite cement applications. The product has been formulated with supplementary cementitious and mineral components including Fly Ash, GGBS and Limestone, together with strength activators.

Composite cement formulations generally utilize combinations of materials such as GGBS, Fly Ash, Limestone, Gypsum and Clinker. The optimum proportions depend on the quality and characteristics of the individual components and the desired performance of the final cement. GB 50 provides a controlled blend designed to simplify the utilization of these supplementary cementitious materials in suitable applications.

Packing and Supply

GB 50 is available in packaging formats designed to suit different customer requirements.

50 kg Bags

Convenient for smaller requirements and construction applications.

1 Ton Bulk Bags

Suitable for larger-volume users and industrial applications.

1.5 Ton Bulk Bags

Available for customers requiring higher-volume handling and supply. Bulk supply options can also be discussed based on customer requirements.

A Sustainable Approach to Construction

GB 50 promotes the effective utilization of Fly Ash and GGBS, industrial by-products that can serve as valuable supplementary cementitious materials.
By incorporating these materials into a controlled composite additive, GB 50 supports more efficient utilization of resources while providing an alternative solution for cement and construction applications.
