Dow proactively replaces mercury PU catalysts

Abstract

In the present scenario disposal of waste is one of the challenging tasks for most of the engineers. Hence an alternative has been found, by using waste material such as EPS (expanded polystyrene) in solid concrete blocks. That has reduced the impact of quarrying operations, processing on environment and also economical. As compared to other materials such as steel and timber, the use of lightweight foamed concrete has numerous advantages, including cost savings, fast compaction, and ease of application. We investigated Cellular Light Weight Concrete (CLC) using Expanded Polystyrene Beads in this study (EPS). CLC is not a recent invention; it has existed since the dawn of time. We have used cement, Manufactured Sand (M−Sand), fly ash (class F), Ground Granulated Blast Furnace Slag (GGBS), polypropylene fibers, EPS, foaming agent that is Benzoyl Alcohol and Water. CLC is used widely because it is less in density. In this research work, Water quality, compressive strength, and thermal conductivity tests were performed on hardened blocks with EPS beads. The addition of fly ash and GGBS to the mix reduced water demand by reducing hydration and carbon footprint, resulting in a reduction in shrinkage, but it also reduced the compressive strength of the blocks by around 25–50 percent. Concrete with a density of less than 1800 kg/m3 is commonly referred to as lightweight concrete. This research focuses on research into lightweight concrete with Expanded Polystyrene (EPS) beads.
