Sustainable and High-Performance Cement Solutions
This type of cement consists of an intimate mixture of Portland cement and Pozzolana.
Maximum percentage of pozzolana: 15-40%
A siliceous or siliceous and aluminous material which chemically reacts with calcium hydroxide at ordinary temperature to form compounds possessing cementitious properties (CSH gel).
Pozzolana + Ca(OH)₂ → CSH Gel
(Cementitious Properties)
Natural and industrial pozzolanic materials
Materials of volcanic or sedimentary origin
Fine-grained volcanic glass formed from explosive eruptions
Highly porous volcanic rock
Sedimentary rock formed from fossilized algae
By-products and manufactured materials
Fine particles from coal combustion in power plants
Calcined clay or metakaolin
By-product of silicon and ferrosilicon alloy production
Agricultural waste product with high silica content
Similar to Portland Blast Furnace Cement
Slower strength development initially, equals OPC at 2 months
Better flow and easier to place than OPC
Ideal for mass concrete construction
Excellent for aggressive environments
Pigments added to white Portland cement
Pigments added to ordinary Portland cement
Has the property of expanding in its early life so as to reduce the contractions induced by drying shrinkage.
Utilizes industrial waste products and by-products, reducing environmental impact
Lower production costs by using waste materials and reduced energy consumption
Superior durability and long-term strength development compared to OPC
