LOW-VOID CONCRETE MIXTURES

The purpose of this study was to modify concrete mix design formulas so that all water over and above that needed for hydration could be replaced with a nonevaporable liquid material or a superwater-reducer of superplasticizer, thus producing a low-void concrete. A water cement ratio of 0.244 to 0.30 was presumed minimal for hydration of the cement. Several polymeric materials, asphalts, oils, and superplasticizers were used. Success was achieved with two latexes, one epoxy, and several superplasticizers. The use of these materials in concrete resulted in improved strength, reduction of air voids and permeability, and improved resistance to corrosive chloride salts. (Author)
