Concrete for Engineers & Contractors

INTENDED FOR

Technicians and Engineers who need a basic understanding or revision of concrete and its properties. The course is intended as a stand alone course or can be combined with our course on Diagnosis Inspection Testing and Repair of Concrete Structures held on the following day.

MAX PARTICIPANTS - 15

THE SPEAKER

Tony Binns- Spent the early part of his career producing, supervising and dealing with Quality Control, before joining the staff of the C&CA’s training centre. With them, he lectured for 14 years on concrete materials topics including mix design and ready mixed concrete. Tony then spent two years with a major civil engineering contractor and now runs his own training company running courses in the UK and overseas.

TARGET BENEFITS

After the course, participants will have an understanding of the fundamental properties of concrete and those of the mix ingredients, including admixtures and reinforcement. Some concrete defects are introduced (with this theme developed on the second day for those taking the 2 day course). Participants will also understand how concrete is specified using British Standards. They will also understand the steps that are taken when non-conformity of the concrete occurs.
