Abstract
In this present era, though the use of cement-based materials plays an important role in growth and development of infrastructure, it poisons the environment by releasing CO2. Based on this interpretation, we are moving forward to opt for a substitute material which will lead us towards a green and sustainable solution. The research aims at identifying the characteristics of High Performance Concrete (HPC) by partially replacing silica fume (10%) and fly ash (20%) with concrete. In this analysis, compressive strength of concrete values for distinct trial blend ratios was determined on the 7th, 14th and 28th day. Based on this compressive strength of the trial mixes the proportions of the material are resolved. Using this outcome, samples are casted with a steady water-to-cement proportion (w / c = 0.28), retained for curing. The study's primary goal is to examine and identify the optimum dosage of superplasticizer, substitute cement with different ratios of silica fume and fly ash and evaluate the mechanical characteristics like compressive and split tensile strength of HPC with Silica Fume and Fly ash with an addition of natural fiber (jute) and later on study later on study the durability properties like sorptivity, acid attack, etc. The following result confirmed that the concrete also works better in mechanical and durability characteristics with jute at 1 percent than any other concrete.
