Review on Application of Lightweight Cenosphere in Construction Material

Abstract There are many industrial waste products used in the construction industry like rice husk ash, fly ash phosphogypsum, marble powder, cenosphere, silica fume, copper slag, granulated blast furnace slag, etc. It is observed that the use of all waste materials is beneficial for improving the properties of cement concrete and also making a hunk of lightweight cement concrete. In that material, the cenosphere is the most economical material in the construction industry, so both waste materials are used in most of the experimental works. This review focuses on the concrete prepared by replacing cement and fine aggregate with the cenosphere at various percentages for the preparation of lightweight cement concrete. The usual way to use cenosphere is up to 30% replacement as fine aggregate or 20% replacement of cement gives good results. These reviews discuss the usability and extraction of cenosphere from fly ash, its properties, and applications. Also observed are the final optimum percentages for compressive strength, split tensile strength, and flexural strength for 7, 14, and 28 days.
