Abstract

In today's concrete, pozzolanic and cementitious elements play a vital role. Not only may pozzolanic or cementitious wastes from industries and constructions help to minimise environmental pollution and energy consumption in the building sector. As a result, the building industry is looking for new ways to create this common material. It may be divided into two categories. One option is to employ supplemental elements in concrete as a partial replacement for cement. Another option is to extend the life of an existing structure. For ecological, economic, and quality reasons, the use of supplemental cementitious materials, whether natural, waste, or by product, is becoming more common in cement making. Fly ash, discarded glass, silica fume, reclaimed concrete, blast furnace slag, red mud, and other materials are used in the design.Cement's contents appear to be identical to those of the primary oxides present in granulated blast furnace slag, SiO2, CaO, Al2O3, and MgO. The effect of using granulated blast furnace slag instead of cement at various percentages on water absorption and sorptivity qualities was investigated in this study. The effects of using fly ash, rice husk ash, and ground granulated blast furnace slag on the water absorption and sorptivity characteristics of concrete with varied CO2 exposure percentages and exposure hours are discussed in this study. The goal of this investigation was to see if concrete could be strengthened with 15 percent fly ash (FA) and rice husk ash (RHA), ground granulated blast furnace slag (GGBFS) as a partial replacement for cement to lessen carbonation effects. The experiments were conducted on concrete specimens with and without CO2 exposure to measure durability features such as water absorption and sorptivity at the age of curing 28 days.
