In this study, geopolymer concrete is prepared by using 100% Ground Granulated Blast furnace Slag (GGBS). Then the GGBS is replaced by Metakaolin from 0 to 25% with the variation of 5% for preparing the specimens. The activator solution consists of Sodium hydroxide of 12 Molarity and sodium silicate in the ratio of 1: 2.5. 550kg/m3 of GGBS is used in this study. A carboxylic based admixture called La Hypercrete S25 is added in the mix by 1% of the weight of GGBS to increase the workability. The studies conducted on the specimens are compression test, split tensile test and flexure test. For conducting the compression test, 54 concrete cubes of size 100mm x 100mm x 100mm are cast for testing at 7, 14 and 28 days. For splitting tensile strength, 54 concrete cylinders with 100 mm dia and 200 mm height are cast for testing at 7, 14 and 28 days. The flexure test specimens are beams of 500 mm length and 100mm x 100mm in cross section are cast. These are 54 in numbers .Specimens are cast by replacing the GGBS by Metakaolin in 5, 10, 15, 20 and 25%. All the specimens are cured for 7, 14 and 28 days and tested for compression, split tensile and flexure. The test results reveal that the strengths are gradually increasing for 5, 10 and 15% replacement of GGBS by Metakaolin and give the highest value for 20% in all the tests. It also shows further increased replacements reduces the test values. It proves that geopolymer concrete performs well in strength properties with GGBS and Metakaolin.

Industrial waste such as Ground Granulated Blast-Furnace Slag (GGBS) and Granite Waste Powder (GWP) is available in huge quantities in several states of India. These ingredients have no recognized application and are usually shed in landfills. This process and these materials are sources of severe environmental pollution. This industrial waste has been utilized as a binder for geopolymers, which is our primary focus. This paper presents the investigation of the optimum percentage of granite waste powder as a binder, specifically, the effect of molar and alkaline to binder (A/B) ratio on the mechanical properties of geopolymer concrete (GPC). Additionally, this study involves the use of admixture SP-340 for better performance of workability. Current work focuses on investigating the effect of a change in molarity that results in strength development in geopolymer concrete. The limits for the present work were: GGBS partially replaced by GWP up to 30%; molar ranging from 12 to 18 with the interval of 2 M; and A/B ratio of 0.30. For 16 M of GPC, a maximum slump was observed for GWP with 60 mm compared to other molar concentration. For 16 M of GPC, a maximum compressive strength (CS) was observed for GWP with 20%, of 33.95 MPa. For 16 M of GPC, a maximum STS was observed for GWP, with 20%, of 3.15 MPa. For 16 M of GPC, a maximum FS was observed for GWP, with 20%, of 4.79 MPa. Geopolymer concrete has better strength properties than conventional concrete. GPC is $13.70 costlier than conventional concrete per cubic meter.

Concrete is one of the most suitable materials in the world which are used for construction. It becomes more versatile because of his suitability in almost all situations. Reinforced structures are subject to corrosion by various means. Carbonation is one of these means that causes corrosion of reinforced concrete structures. The service life of the structures has been reduced due to the deterioration of the structures because of the corrosion of the reinforced concrete due to carbonation. This paper focuses on the effect of carbonation on the mechanical properties of concrete composed of mineral admixtures, such as ground granulated blast furnace slag and silica fume, by partial replacement of the cement. In this experiment, silica fume replaced cement in 5%, 10%, 15% and ground granulated blast furnace slag replaced the cement in 10%, 20%, 30%. Samples such as cubes, cylinders and prisms were casted and cured. Certain number of these specimens were also placed in carbonation chamber and tested for compressive strength, tensile strength and flexural strength. Normal concrete samples are also tested and the results are compared.
