The Federal Highway Administration has approved the use of three (3) polymer-modifiers in concrete as alternates to low slump dense concrete (LSDC). These products are: Dow SM Modifier "A", Thermoflex 8002 and Arco-Dylex 1186. The Department introduced this study to verify the results obtained by the Federal Highway Administration, but tested and evaluated under Louisiana conditions. A new product Duralguard Modifier "E" with similar properties was also included in the study. Primary concentration was focused on reduction of chloride penetration into the concrete. The test results on previously approved polymer modifiers confirmed the FHWA findings. The chloride content of concrete specimens of Duralguard Modifier "E" was in excess of FHWA limits. (FHWA)
