Fly ash: Objective To investigate the impact of different

Objective To investigate the impact of different percentages of slag and fly ash on the compressive strength and carbon footprint of lightweight concrete. • Highlighting the aim to minimize carbon emissions associated with concrete production while optimizing concrete strength Title: Fly Ash , Slag, Silica Fume, and Rice Husk Ash in Concrete: A Review Author (s): V. M. Malhotra Publication: Concrete International Volume: 15 Issue: 4 Appears on pages (s): 23-28 Keywords: admixtures; blast furnace slag; fly ash ; hydraulic cements; pozzolans; rice husk ash ; silica fume; Materials Research DOI: Date: 4/1/1993 Abstract: Portland cement is a highly energy-intensive product, and therefore, to save energy and conserve resources, considerable efforts are being made to find ... In this article named “ Production of Fly Ash “, the process of fly ash production will be discussed briefly. Fly ash is a by-product of burning coal in an electrical generating station. The following figure shows a typical layout of a coal-burning generating station. Fly ash is used in concrete and other portland cement-based systems primarily because of its pozzolanic and cementitious prop-erties. These properties contribute to strength gain and are known to improve the performance of fresh and hardened concrete, mortar, and grout. The use of fly ash typically results in more economical concrete construction.
