Green Concrete

Abstract

In the manufacturing of Portland cement concrete, fly ash is frequently utilized as a supplemental cementitious material (SCM). High-volume fly ash (HVFA) concrete is concrete that contains a significant proportion of fly ash. Occasionally, it is also referred to as "green concrete." Fresh concrete's properties include setting, workability, bleeding, segregation, hydration, and air entrainment. The majority of these qualities depend on the Water-to-Cement Ratio, Optimal Temperature, Cement Content, Cement Type, Cement Fineness, Relative Humidity, Admixture Type, and Aggregate Quantity. The addition of standard amounts of fly ash to Portland cement concrete has economic, environmental, and performance advantages. The economic and environmental advantages of adding fly ash to concrete are lower cement manufacturing costs, decreased greenhouse gas emissions, and enhanced sustainability. The purpose of this study is to examine the effect of high-volume fly ash on the qualities of fresh concrete, with the physical and chemical properties of high-volume fly ash evaluated in various articles serving as the research materials. The study came to the conclusion that up to 50 percent fly ash can be used in most elements, as long as the early-age strength requirements for concrete are met.
