Material Properties of Concrete Containing Nano silica, Alccofine and Polypropylene fibers

Abstract

The strength properties of polypropylene fiber concrete partially substituting cement with an optimal combination of nano silica and alccofine 1203 are discussed in this research. The design mix utilised in this study was M25 grade concrete, with polypropylene fiber employed in varied proportions of 0, 0.1, 0.2, 0.3, and 0.4 percent in partial replacement of cement, and alccofine 15% and nanosilica 1% constant to total cement weight. For all mix quantities, the water binder ratio was 0.5. For the desired workability, superplasticizers were added using a trial and error procedure. On curing days for 28 days of concrete, the compressive strength, modulus of rupture, and modulus of elasticity were measured. The highest compressive strength, flexural resistance, and modulus of elasticity of the fiber reinforced concrete with alcofine and nano silica were 34.01 MPa, 8.5 MPa, and 29.22 GPa, respectively. Alcofine and nano silica concrete are compared to normal concrete in terms of strength.
