Presented by Brent Rollins, Vice President of Business Development: Spray-Lock Concrete Protection, Chattanooga, TN
Brent talks about the following:
Research, coupled with widespread use of colloidal silica during the last decade, have found that it has the potential to increase strength and durability of concrete. One of the key benefits of using colloidal silica is the available surface area of the reactive silica.

Cracking in concrete needs to be minimised as far as possible, or at least controlled to within acceptable limits to minimise costly repairs and to enhance durability. The correct classification of cracks will determine the remedial measures to be taken which can often be very challenging.

CONSOLIDATION OF THE CONCRETE INDUSTRY BODIES
Consolidating the existing concrete bodies into one is no easy task as these bodies have different objectives, structures, members, finance models, value offerings and deliverables. One thing they all have in common though is: THE LOVE OF CONCRETE!
Bryan Perrie (MD of TCI and CSSA Board Member) shed light on the progress of the consolidation process which is gathering momentum fast towards a workable solution for the benefit of all role-players.
