Society – London & South East Region are holding an early-evening
technical meeting to offer guidance in the often misunderstood requirements of
consistence retention and retardation. These two facets of modern concrete
technology are not the same and there are subtle differences between what the
two mean to a concrete.
With an increase in the requirements
for concretes with consistence retention requirements of typically up to four
hours and for them to then behave as conventional concrete in the setting and
hardening phase, many RC frame and Piling contractors are specifying such
properties, whilst to the vast majority of concrete users, the mistake is to
believe retention and retardation are the same.
The event will offer two presentations
on the subject, the first from the point of view of the admixture supplier, and
we are pleased to say this will be by Mr
Ian Ellis, of BASF. Our second
presentation will be from the viewpoint of the concrete supplier, and we are
pleased to say this will be by Mr Jasen
Gauld, of London Concrete.
