Surface characteristics, pore size and enhanced chemical resistance using graphene oxide nano sheets in ultrafine slag cement mortars

Concrete gets exposed to weathering. Thus, the structures sustain significant damage, significantly reducing the concrete's durability properties. Nanofillers can improve a material's ability to hydrate, which enhances the material's fresh, toughened and durability assets. The presented work is cement mortar with Ordinary Portland Cement with 10% Ultrafine slag (UFS) and various Graphene oxide (GO) mixtures (0.01% to 0.04%) subjected to 3% sulphuric acid to assess their chemical resistance. The Brunauer, Emmett and Teller analysis appraised the preliminary research by exposing the surface attributes and pore size dimensions. The test result elucidates GO 0.03% with 10% UFS was best. The evaluation of acid-exposed specimens is based on changes in the specimens' size, mass and visual scrutiny. The highest sulphate and acid resistance were observed for CMS4 and CMA4 with the least mass, length and flexure strength loss at 28 and 56 days. The surface was unaffected in microscopic studies, and there was no loss of flexural strength.
