INSEE MAHAWELI MARINE PLUS is compatible with:
INSEE MAHAWELI MARINE PLUS is used for:
Both slag and fly ash variants of INSEE MAHAWELI MARINE PLUS display inherent chemical properties that improves resistance over time, thanks to the pozzolanic reaction between the free lime of the hydration of the clinker and the active siliceous in the fly ash and slag with the formation of more calcium silicate hydrate. This result in a denser concrete with enhanced strength for concrete structures and highly appreciated by concrete blocks producers and prefabricated concrete elements.
Slag and fly ash have inherent chemical properties that produce denser concrete with low permeability. By decreasing bleed channels, capillary channels and void spaces in the concrete, INSEE MAHAWELI MARINE PLUS lowers permeability of the concrete, reducing the potential for corrosion of reinforcing steel, adding further durability to building structures.
The enhanced workability of INSEE MAHAWELI MARINE PLUS ensures improved, smoother and aesthetically pleasing surface finishing of concrete structures and applications. This in addition to the inherent sulphate resisting property in both fly ash and slag variants, results in less efflorescence – crystalline salt deposits – forming on the uniform concrete surfaces.
The high strength developed in concrete produced with INSEE MAHAWELI MARINE PLUS allows for a large reduction of admixture and cement consumption in the mix, reducing raw material costs to a great extent. It also leads to optimized structural design that allow for thinner, lighter and fewer structural elements. The optimized mix designs also result in curling and heat, less shrinkage and lowering life cycle costs, through increased service life.
