Polymer effect on the rheological properties of the PPC blends

Abstract

A study was carried out on rheological properties of PCC (polymer concrete with cement) fresh blends containing polymers soluble in water and epoxy resins. The work refers to determine yield and plastic viscosity of fresh concrete according to the polymer weight. It was used methilcellulose as polymer and an epoxy resin, in different proportions. It was also carried out physico-mechanical tests on hard concrete. The study revealed that the addition of polymer matrix to produce PCC concrete, has a pronounced effect on the rheological property of freshly mixed. Influence of polymers on these properties is due to both the content of colloidal particles, and the amount of air present in the mixture due to stirring and mixing the paste.Changes that they produce polymer emulsions are found in terms of both flow and the viscosity value, and decreasing. This allows the scientifically and technologically, as they are controlled and adapted to specific requirements.Compressive strength of epoxy resin blends were found to be higher than those of mixtures containing methylcellulose.
