Incorporation of Class C and Class F Fly Ash in Concrete Mix: Effect on Rheological and Strength Properties | Chapter 11 | Technological Innovation in Engineering Research Vol. 7

 In today's civilised world, cement concrete is recognised as a versatile building material for the development of varied infrastructure. Since many years, fly ash is most likely one of the prospective additional cementious substitutes for cement. Fly ash, a byproduct of thermal power plants that contains aluminous and siliceous material, combines with calcium hydroxide to produce calcium silicate gel, which accelerates the hydration of cement. In the current study, an effort is made to pinpoint and examine several elements that affect fly ash's reactivity. When used in concrete, fly ash reduces water usage and early-age strength while increasing later strength, durability, acid and sulphate resistance, flowability, segregation, and rheological qualities. In this present work, detailed study of the various mechanical properties (tensile, flexural and compressive strengths) as well as bond strengths is incorporated. This paper highlights detailed literature review on various strength properties of various concrete specimen conducted in past research works. This research investigation contains study on hardened fly ash - concrete composites with various proportions of fly ash (low content max. 50% with and without other chemical and mineral admixtures). Research investigation emphasizes multi-dimensional effects of chemical admixtures influences on the concrete properties as well as investigation of properties of high-volume fly ash to further support the case of fly ash-based structures.
