An experimental study of the strength and durability characteristics of high-performance concrete including nano-silica

High performance concrete to improve efficiency over the course of its lifetime without sacrificing its quality. (HPC). In this project, a mix ratio for high-graded concrete is calculated and the optimal percentage of silica fume (SF) is added as a pozzolanic reactor. For filling voids in concrete, nano silica (nS) is an appropriate cementitious material that can be added in different amounts to increase density and impermeability (2). In order to meet the workability requirements of recent concrete, super plasticizer (Conplast SP430) is favored over the addition of nano silica and silica fume. HPC with varying levels of nS had its mechanical properties (compressive and split tensile strength) and durability properties (acid resistance and water absorption test) investigated. The findings of the pertinent tests are taken into account to determine the ideal level of nS in HPC. Based on the test findings, the reinforced high performance concrete beams’ performance was evaluated, and the load deflection curve indicates that the member’s behavior has improved.
