STRENGTH IMPROVEMENTS IN MORTAR AND CONCRETE BY ADDITION OF EPOXIES

To raise the tensile strength of cement mortar and concrete, we conducted a series of experiments in which suitably formulated spoxy resins were added to standard cement mortar and to selected concrete mixes. Tensile and compressive strength measurements were made on various formulations, and strengths were determined as a function of epoxy-added content. Both tensile and compressive strengths are apprecibly increased by additions of epoxy to cement mortar and concrete. These additions are 5 and 10 percent by weight of mortar for the cement mortar and concrete respectively. The effects of polymer additions on aggregate-paste bond have been studied by use of a scanning electron microscope. The influence of the epoxy on workability, stiffness, and water absorption is also discussed. /Author/
