Investigation of Waste Paper Cellulosic Fibers Utilization into Cement Based Building Materials

Abstract

Phosphogypsum, fluorogypsum, lime sludge, hypo sludge and red mud include poisonous elements that degrade the strength and
qualities of building materials, posing disposal issues as well as health risks. This manuscript is about an experimental study on
concrete strength, durability, and the best proportion of partial substitution of cement with 0%, 10%, 20%, 30%, 40%, and 50% lime
sludge and also presents to create low-cost concrete in another term call it as Economical Concrete (E-Concrete), lime sludge is used
as a substitute for Portland cement. Paper production generates a significant amount of solid waste. Separation of low-quality paper
fibers, dyes, and kaolin coating, which gives magazines a shiny appearance, produces waste sludge. Every year, this paper mill muck
takes up a significant amount of local landfill space. In order to lessen disposal and environmental issues, investigations were
undertaken to produce low-cost concrete by blending different ratios of cement with lime sludge.
