In this study, the affection of different ratios of water-cement, polymer-cement, fiber-cement and hybrid fibers on mortars have been examined. It has been observed mechanical, workability, fluidity and shrinkage properties of polymer modified mortars during experimental period. In experiments, polymeric additives such as acrylic-styrene resin, polycarboxylate eter based superplasticizer and shrinkage reducing agent, fibers such as 12mm, 3 mm glass fibers, 6mm surface treated glass fiber, and polypropylene and nylon fibers have been used. A mathematical model was evaluated which is based on surface response model. Central composite design has been used as a design of experiment. The mortar specimens have been cured 2 days in water pool. After 60 days, their mechanical tests have been performed. As results of experiments, hybrid fibers improve flexural properties of mortars and also make positive effect on processability properties. Usage of single 12 mm glass fibers and 6 mm surface treated glass fibers have better effect on compressive properties than hybrid fibers. Usage of high amount of styrene-acrylic cement modifier has affected the mechanical strength negatively.
