RETRACTED: Investigation on fluidity, microstructure, mechanical and durability properties of snail shell based graphene oxide cement composite material

Abstract

• Inclusion of Snail Shell Powder with Graphene Oxide Cement Composite offers Improved Dispersion. • Replacement of Cement with Snail shell powder in Graphene oxide Cement composite helps to enhances the fluidity of composite. • Snail shell-based Graphene Oxide Cement Composite Helps to the formation of Ettringite. In recent years, there has been a more usage of Graphene Oxide nanomaterial to enhance the desirable qualities of cement-based composites. The fluidity of cement composites and the workability of concrete, on the other hand, may be lowered as a result of the introduction of graphene oxide (GO). In this research, a simple and inexpensive additive snail shell powder was employed to increase the fluidity of graphene oxide cement composites. Additionally, the microstructure, mechanized, and durableness performance of snail shell (SS) based graphene oxide (GO) cement composites was studied. Snail-Shells are examples of bio-shell debris that is wasted from restaurants and the seas every day. Because of poor maintenance of waste, SS are deposited as rubbish on vacant areas and in landfills. The snail shell powder has a spherical shape and has a pozzolanic character, similar to that found in cement. In the current study, snail shell powder was employed in GO-cement composites to substitute a portion of the cement, and the performance of the composite material's fluidity, microstructure, mechanical, and durability characteristics were investigated. The impact of snail shell powder was investigated at 10 wt%, 15 wt%, and 20 wt%, replacement of cement, with graphene oxide (GO) addition ranging from “0.01 wt%, 0.02 wt%, 0.03 wt%, and 0.04 wt%”. The amount of snail shell powder added to the GO composite enhanced the fluidity. A result of the reduced water requirement, the spherical form of the snail shell powder (SSP) and the pozzolanic nature of the SSP, the improved fluidity of the GO-cement composite was obtained. The SEM examination were used to establish the micro structural study of the cement composite. In the SEM pictures, it could be shown that the combination of SS and GO changed the nature of structure of the composite from one that was porous to one that was significantly pore filled, resulting in better mechanical and durability characteristics. At 3, 7, and 28 days of curing, snail shell based GO-cement composites demonstrated stronger compressive and flexural strengths than the control sample, despite the fact that the snail shell powder dose was less than 20 % of the total weight of the cement. Finally, the inclusion of snail shell powder material to the GO-cement composite resulted in an excellent solution to the fluidity issue that had been encountered.
