Abstract

Abstract: Due to its extraordinary adaptability as a construction material, concrete is the single most utilised produced substance on earth, with an annual production surpassing 2 billion metric tonnes (Crow 2008). The damaging impact on the environment caused by the manufacture of concrete's components is one disadvantage as a construction material. These negative effects can be reduced by using alternative/green ingredients in concrete in place of Portland cement and natural aggregates. Any construction project's overall cost directly relates to the amount of concrete utilised in the project. The largest energy- and environmentally-demanding ingredient in traditional concrete is Portland cement. In the process of making it, fuel is burned to heat the raw materials to about 1,500°C, which decarbonizes the limestone. Due to fuel combustion and decarbonization, 0.81 kg of CO2 is emitted for every kilogramme of cement during this process (Hendriks et al. 2000).The most substantial single material component in the constructed environment is often concrete. Significant environmental and financial benefits might be realised if the embodied energy of concrete can be decreased without compromising performance or raising costs. The main ingredients of concrete are Portland cement, aggregate, and water. Although Portland cement generally only makes about 12% of the mass of concrete, it is responsible for 93% of the total energy contained in concrete and 6–7% of global CO2 emissions (Mehta 1998). There are a lot of papers available, replacing cement with In this study, the strength of concrete is examined, and the costs of OPC concrete and concrete with ALCCOFINE are compared. Silica fume is typically recommended as the ideal cement extender in high performance concrete applications where high strength and low permeability are the primary criteria. Despite the fact that silica fume is known to promote durability, the increased water content in concrete frequently negates its addition.
