Abstract

The concrete admixture Ipanex (Registered trademark) manufactured by IPA Systems Inc. was submitted to the Iowa Department of Transportation (Iowa DOT) New Products Committee on April 15, 1998. The New Products Committee requested that the Iowa DOT Materials Laboratory evaluate the durability, corrosion inhibiting and concrete permeability reduction effects of this admixture. This report is intended to present the results of testing in Iowa DOT materials laboratories, review a Pennsylvania State University report, as well as review the IPA Systems Inc. marketing literature. The objective is to provide the New Products Committee with a recommendation concerning approval of this product based on the information gathered. The portland cement concrete admixture Ipanex (Registered trademark) did not show any significant benefit in terms of improvement in areas of permeability, chloride resistance and strength in the testing performed at the Iowa DOT. The literature and reports reviewed did not provide enough credible evidence to refute this conclusion. Additionally, the benefits ascribed to this product can be more economically achieved using other currently available products such as slag and silica fume. The recommendation is that this product not be approved for use on State projects in Iowa.
