INSEE Rapidflow Plus

High Performance Concrete

INSEE RAPIDFLOW PLUS is a high performance Blended Hydraulic Cement of both ground granulated blast furnace slag (GGBFS) and fly ash variants, producing overall high performance and high strength concrete for industrial and infrastructure projects.

Produced with a perfected combination of cementitious binders that is the result of years of research and development, INSEE RAPIDFLOW PLUS develops high strength in concrete that allows a reduction in structural element sizes, contributing to the increased cost efficiency of the construction.

Features and Benefits

High Performance Concrete
INSEE RAPIDFLOW PLUS exhibits enhanced fresh and hardened properties of concrete including high strength, increased durability, lower permeability, increased corrosion resistance and reduced thermal stress to structures, resulting in the elevated overall performance of concrete structures.

High Strength Concrete
Both slag and fly ash display inherent chemical properties that produce 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 results in denser concrete with enhanced strength that serves as a tool for engineers to optimize concrete mix designs.

Cost Efficient Concrete Mix Designs
The high strength developed in concrete produced with INSEE RAPIDFLOW 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 less shrinkage, curling and heat, lowering life cycle costs through increased service life.
