This study introduce a new trend of utilising Prepackaged Polymer-Modified Mortar (PPMM) as a modifier to ordinary concrete for producing Polymer-Modified Concrete (PMC). The experimental study articulates the strength development of proposed polymer-modified concrete. A range of quantities of PPMM, as 5 to 50%, were mixed with ordinary concrete of 30 N mmG2 characteristic strength to produce polymer-modified concrete and to evaluate for compressive strength, tensile strength, density and workability. The material behaviour in terms of compressive strength and tensile strength, together with density and slump was investigated by casting and testing cubes of 100 mm size, cylinders 100 mm dia and 200 mm height. This Preliminary study shows that compressive strength and tensile strength is improved significantly by inclusion of various quantities as percentages of PPMM to ordinary concrete and curing regime as specified by JIS. PPMM dosages of 5 to 20% resulted considerably higher compressive and tensile strength than that of ordinary concrete, on the other hand further increase in percentage of PPMM gave less strengths. Results demonstrated more prominent percentage increase in tensile strength than compressive strength of produced polymer-modified concrete. Polymer-mod fied concrete mixes with all percentage dosages of PPMM were found cohesive and workable.
