INVESTIGATION OF PROPRIETARY ADMIXTURES

Three special water-reducing admixtures for concrete were evaluated according to test method CRD-C 87-72. Tests were made to determine the effects of these admixtures on the properties of concrete. Air-entrained concrete mixtures were made with and without these admixtures. All three of the admixtures permitted water reductions exceeding 15 percent. The admixtures met all the requirements of CRD-C 87-72 except for frost resistance. /Author/
