Abstract:Long-lasting durable concrete is a must-have for departments of transportation (DOTs) in today’s
construction and economic climate. Many entities are turning to alternative concrete mixtures to
ensure long-term durability such as ternary mixtures, lower w/cm ratios, lower cementitous materials
contents, and alternative binders, such as Ekkomaxx. This project will evaluate concrete produced
with 100 percent fl y ash combined with an activator provided by Ceratech. The use of fl y ash as a sole
binder 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 owner (Ceratech) and the user (DOTD) to gain a more in-depth understanding
of the interactions associated with the use of 100 percent class C fl y ash systems produced with
Ceratech’s activator.
