Filler slab with partial replacement of cement by eggshell powder

Abstract

Currently India has taken a major initiative in developing the infrastructure to meet the requirements of globalization in the construction industry. Considering building element like slab, more concrete is wasted in the tension zone, since the tensile forces are taken by the steel reinforcement. To overcome this wastage of concrete in tension zone, a new cost effective method called as Filler slab technique is used. Low price and lightweight filler substance like Mangalore tiles, that will decrease the dead weight in addition to the total cost of this slab to some degree. Being environmentally accountable, the utilization of waste substances is a Vital step in creating a sustainable future. The Eggshell, which is usually disposed as a poultry waste can be used as an alternate of cement in powdered form, since the shell is made up of Calcium having a chemical composition same as limestone. Partial replacement of cement by eggshell powder is done in different proportions like 2.5%, 5%, 7.5% & 10%. In this paper, the filler slab has been created additional cost effective with the addition of eggshell powder because partial replacement of cement. Following a healing period of 28 days, there's a version in compression and flexural strength of concrete using eggshell powder compared to conventional concrete.
