High Strength Concrete (HSC) has been developed over the past several decades, prepared by introducing water-reducing admixtures and high strength cementitious materials. The demand for these materials has grown significantly over the last 10 to 15 years.
The key drivers of the development of HSC are the long term use of concrete construction, the design of taller buildings, and the growing demand for thinner columns or wall elements to create more open-planned spaces.
The requirements for HSC are evolving, and will likely continue to change:
Most producers of HSC understand the factors that affect compressive strength and have the knowledge to engineer them to achieve their desired concrete strength.
The selection of raw materials is of utmost importance before they can be optimised into the required mix design:
High Strength Concretes are more sensitive to changes in constituent material properties than conventional concretes. This means they require a greater degree of quality control for a successful production.
EverSure Type GP is manufactured at Golden Bay Cement, and consistently meets the requirements to produce High Strength Concrete.
