Abstract:Long-lasting, durable concrete is a must have for DOT’s in today’s construction
and economic climate. Many entities are turning to alternative concrete
mixtures, such as ternary mixtures, lower w/cm ratios, lower cementitious
materials contents, and alternative binders such as Ekkomaxx, to ensure long
term durability. This project will evaluate concrete produced with 100% class C
fl y ash combined with an activator provided by Ceratech. The use of class C fl y
ash as a sole binder for production of portland cement concrete can be diffi cult
and the aforementioned product allows the control of the set times to allow
better usage of class C fl y ash as the sole binder. This project will enable the the
Louisiana Department of Transportation and Development (DOTD) to gain a
more in-depth understanding of the interactions associated with the use of 100%
class C fl y ash systems produced with Ceratech’s activator.
