WHO'S WHO IN CONCRETE

Concrete additives: The proof is in the mix design

M

uch like it is at a restaurant or a bakery, where the importance of the recipe cannot be underestimated or tampered with in order to ensure a successful dish or pastry, the concrete mix design is of critical importance in the world of construction. This step sets the foundation for the concrete work on any project and is imperative that it is done correctly – with all required results and requirements being met. Unlike a chef or a baker – failure is not an option in construction.

High performance As a leading supplier of additives for concrete, Mapei has built a reputation of providing valuable technical assistance and insight into the development of suitable, high-performing concrete mix designs on local and global projects. “We believe that – by working together with our customers locally, while accessing our international global experience within the Mapei group – we are best equipped to provide optimal support and input to all our customers,” claims Servaas le Roux, product manager: Concrete Admixtures. “Each site or project presents its own set of variables that need to be accounted for when developing a suitable mix design. Experience and in-depth knowledge are vital assets at the point of development. This, however, is not where it ends,” he continues. “Once on-site, there are softer variables that can and often do arise, which can impact on the concrete. As such, Mapei sees the project though to the end alongside our customers, to ensure the best results – always,” adds Le Roux. “The one thing we don’t compromise on is customer service and support; it’s a non-negotiable for Mapei,” he concludes.
