| Popis: | In this research, the main investigation on macro level and durability characteristics of medium and high strength geopolymer concrete composites, where cement is completely replaced with the cementitious material integration of granulated ground blast furnace slag (GFS) and metakaolin (MKL) along with sodium hydroxide (8 M, 10 M, 16 M and 20 M) and sodium silicate solution were rummage-sale as energizing the binders. Many researchers are concentrated on the single replacement of binding material whereas in this investigation composite replacement of binding material is performed. Mechanical and engineering properties are determined for evaluating the strength attributes of the modified composite geopolymer concrete. GPC1 mix specimens attained the maximum compressive strength (CS), split tensile strength (STS) and flexural strengths (FS) values of 63.22, 2.63 and 10.6 for 28 days and 67.55, 3.1 and 12.8 for 90 days. GPC1 and GPC4 specimens exhibit better resistance to both H2SO4 and HCL environment. |
