Abstract
Concrete, in its simplest definition, is a building material obtained by combining water, cement and aggregate in certain proportions. The basic chemical components of concrete consist of these three materials. However, it has been an important issue to develop concrete against many effects other than its existing mechanical and physical properties, thanks to its economic and easy accessibility. Fibers that have been added to concrete in order to improve the tensile stresses of concrete since the past have been expanding their range today. PVA fiber reinforced concrete, known as engineered cementitious composite (ECC), improves the low tensile stress of concrete and accordingly provides high toughness. ECC concrete is a material developed with a micromechanical mix design. However, the use of ECC concrete is limited due to its disadvantage in terms of easy accessibility and economy. In this study, the physical and mechanical properties of 1 drop of glycerine added PVA fiber and 2 drops of glycerine added PVA fiber concretes were investigated. The physical and mechanical properties of the samples were investigated by adding 2% PVA 1 drop of glycerin fiber and PVA 2 drops of glycerin fiber into the concrete mix design prepared with the micromechanical design. According to the findings, an increase was observed in water absorption, porosity and electrical resistivity tests compared to the control sample and commercial PVA fiber samples; A decrease was observed in the charpy experiment.
