Abstract
Polymer concrete is gaining increased popularity as a new construction material due to its high compressive, tensile and flexural strengths, short curing time, impact resistance, chemical resistance and freeze-thaw durability. It can be used to repair concrete structures, build slabs and beams of small cross sections and sleepers. There is a great potential of using this material in other structural applications as well. Research work in polymer concrete originated from well over couple of decades. In all of these research programs, either polymer concrete or mortar was made using different types and percentages of resin combined with sand, fly ash and coarse aggregate. The samples thus made were tested for the compressive strength, stress-strain relationships, tensile strength, modulus of elasticity and flexural strength. However, there is no common agreement among the research community about the effect of fly ash on these mechanical properties of polymer concrete.
Therefore, this paper investigates the available literature and the experimental results from authors' experimental programs in order to generalize the effect of fly ash on the mechanical properties of polymer concrete. The addition of fly ash as filler material, results in a reduction in the amount of resin, and an increment in the compressive strengths and an increase in the modulus of elasticity. Split tensile strength and flexural strength exhibits a decreasing trend with the increasing fly ash content.
