3 constructive and sustainable solutions to cement manufacturers Cemax technology Fosroc has developed Cemax A unique product solution which focuses on adding value to cement production, considering all aspects relating to cement manufacturing process. Fosroc s Cemax works in number of different ways to improve the efficiency and effectiveness of grinding action during production and providing important application benefit in terms of Flow, Compressive Strength and Consistency of finished product. Cemax... Works as GRINDING AIDS & PERFORMANCE ENHANCERS to meet various objectives of cement plants for their comminution process like Cement Mill, Raw Mill and Coal Mills. Fosroc s Cemax range of grinding aids and performance enhancers can save up to 40% of grinding cost. Cemax Products Grinding Aids for Cement Mill Performance Enhancer/Quality Enhancer Special additives like Raw mill and Coal mill grinding aids to cement manufacturers? Grinding Aids Improved particle size distribution Improved Pack Set Index (flowablity) Performance Enhancer/Quality Enhancer Improved strength of cement Improved desired quality of cement Improved cement Pack Set Index (flowablity) Special Additives Improved cement properties of Cemax technology... Reduced agglomeration improvements in: energy consumption, cement fineness and mill output Improved consistent quality of cements with Better flow characteristics Improved particle size distribution Increased strength Increased composites addition rate in the cement Improve setting time, especially incase of PPC and PSC

4 Cemax grinding AIDS Cemax solution to reduce agglomeration in cement grinding Reduced agglomeration Reduced cement Pack Set Index (improved powder flowability) Mechanism of agglomeration O Ca O Ca Reagglomeration continues during grinding process Cement particles agglomerate between each others due to static charges Ca O Ca O Cemax, highly dipolar organic, adsorbs onto clinker Cemax neutralizes electrostatic charges on newly formed cement particle surfaces Ca O Cemax adsorbs into small cracks clinker, saturate the charges and reduce the surface energy forces Neutralized particles reduce agglomeration between cement particles Grinding Aid Actions Cemax is an organic compound that mostly active in the mill through adsorption on the particle surfaces It generates a very thin monomolecular film around the particles which soften some electrovalence bonds as well as neutralize electrostatic charges on the particle edges Electrovalences of its organic group component act on the calcium (Ca ) and oxygen (O ) bond. Ion formed by CEMAX, (OH(CH 2 )n) neutralized all electrostatic charges on the clinker and cement particles which eliminate coating and provide higher fluidity of the ground materials Increased Mill Output Reduced production cost per unit of cement Improved cement flowablity/ Reduced Pack Set Improved Mill Equipment Performance CEMAX Grinding Aid Advantages Values Improved Mill Efficiency Reduced recirculation load Reduced Blockages in Diaphragms and grids Reduced Equipment wear and tear Reduced Silo outlet blockages and caking Improved cement transportation efficiency

5 CEMAX PERFORMANCE ENHANCERS Introduction Performance enhancer improves clinker grindability and cement quality by advanced chemical reactions It is a second generation of cement additives More and more companies now prefer to use Performance enhancer depending on the local cement market requirements and maturity Enhanced cement quality Reduced agglomeration Reduced cement Pack Set Index (improved powder flowability) Improved cement quality by solving the following Low quality clinkers New requirements from customers and market Improved plant profitablity by producing cement with lower clinker content Increased cement mill output Values Reduction in Equipment wear and tear Producing better and unique type of cement Reduction in CO 2 Emission through clinker replacement Improvement in plant operation similar to the effects of grinding aids CEMAX Grinding Aid Advantages Cemax molecules adsorb onto newly formed cement particles, reduces agglomeration. Individually, Cemax molecules enhance cement performance according to specific requirements. % Increase in mill output g per tonne of clinker g per tonne of clinker g per tonne of clinker Cement blaine value 7 Performance Enhancer Actions: Higher Early Strength and Faster Setting Time Optimization of the particle size distribution Acceleration of the hydration of C3A, Cemax accelerates the formation of Ettringite as well as its transformation into monosulphoaluminate to improve cement early strength. Reduce Pack Set Index (Improve cement dry flowablity) Ion formed by Cemax neutralized all electrostatic charges on the clinker and cement particles which eliminate coating and provide higher fluidity of the ground materials. Higher Late Strength Accelerate the hydration of ferrite phase, Later, it leads to the promotion of silicate phases hydration which lead to better late strength enhancement. Reduces production cost and improves cement plants profitability. Improves cement physical properties which will improve cement quality and allow higher clinker replacement. Cemax Performance Enhancer Advantages The FUTURE is insight.
