Abstract:

This experiment was designed to investigate some of the structural properties of polymer modified concrete. 3x6 in (7.6x15.2 cm) cylindrical specimens were prepared and tested in simple compression and split tension to obtain the entire stress-strain relationship for this concrete.

Abstract:

Polymer cement concretes prepared by substituting at least 20 percent of expoxy resin for cement into ordinary Portland cement concrete mixes showed increased compressive strengths. The addition of flyash to the epoxy cement mixes increased the compressive strength further. Preliminary tests indicated that the presence of the epoxy resin does not inhibit the hydration of the Portland cement.

Abstract:

It was found that strain at maximum compressive and tensile stress of polymer-modified concrete became steadily greater with the increasing polymer content . .Experiments were carried out with shear walls made of the polymer-modified concrete in order to examine the improvement of ductility and toughness under the shear force.

Abstract:

Techniques for producing lightweight insulating-type composites with uniform polymer distributions have been developed. Three lightweight aggregates, perlite, vermiculite, and foamed glass, were evaluated and perlite was selected for continued evaluation, Two monomers, methyl methacrylate (MMA) and polyester-styrene, were used in thse studies.
