Introduction
Binders have had a role in the construction industry since pre-classical times. Certainly the 2nd century Romans mixed lime with pozzolan and aggregate to produce “bitunium”, the forefather of today’s concrete. Today, international standards govern the production of binders to achieve a high level of performance consistency.

Geo-Con offers a vast range of apparatus that satisfies the requirements of most of these standards, both manufactured by us and imported from the world’s leading manufacturers.
