S3: E4 - Improving Concrete Durability with Colloidal Silica
Thursday, 17 March 2022
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.

S3: E6 - CRACKING IN CONCRETE
Thursday, 19 May 2022
by Dr Roderick Rankine
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.
