INSEE MAHAWELI MARINE PLUS is a Blended Hydraulic Cement of both ground granulated blast furnace slag (GGBFS) and fly ash variants available for the first time in the local retail market.
The performance enhancements exhibited by slag and fly ash cements in their respective concrete mixes have over time become equally important to residential constructions and other stakeholders in the retail market. The versatility, strength and longevity of the concrete mix has made INSEE MAHAWELI MARINE PLUS highly attractive to the local market segment that is responsibly contributing to sustainable construction practices.
Faster demoulding time and better finish, coupled with the above mentioned product performances make it ideal for the Concrete product manufacturing (CPM) industry

INSEE MAHAWELI MARINE PLUS is used for:
Both slag and fly ash variants of INSEE MAHAWELI MARINE PLUS display inherent chemical properties that produces an additional calcium-silicate hydrate gel (CSH) – the glue that holds the concrete together – by continuously reacting with the water and other chemical elements in the mix over time. This produces denser concrete that enhances strength in structures, and increased compressive strength in other applications such as concrete block production.
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.
