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.

Geopolymers are considered to alternatives to Portland cement, providing an opportunity to exploit aluminosilicate wastes or co-products with promising performances in the construction sector. This research is aimed at investigating the strength of fly-ash-geopolymers of different ages. The effect of granulated blast furnace slag (GGBFS) as a partial replacement of fly ash (FA) on the tensile (ft) and compressive strength (fc), as well as the modulus of elasticity, is investigated. The main advantage of the developed geopolymer mixes containing GGBFS is their ability to set and harden at room temperature with no need for heating to obtain binding properties, reducing the energy consumption of their production processes. This procedure presents a huge advantage over binders requiring heat curing, constituting a significant energy savings and reduction of CO2 emissions. It is found that the development of strength strongly depends on the ratio of fly-ash to granulated blast furnace slag. With the highest amount of GGBFS, the compressive strength of geopolymers made of fly-ash reached 63 MPa after 28 days of curing at ambient temperature. The evolution of compressive strength with time is correlated with the development of ultrasound pulse velocity methods, which are used to evaluate maturity. The modulus of elasticity changes with strength and the relationship obtained for the geopolymer is presented on the basis of typical models used for cement-based materials. The tensile to compressive strength ratios of the tested geopolymers are identified as higher than for cementitious binders, and the ft(fc) relationship is juxtaposed with dependencies known for cement binders, showing that the square root function gives the best fit to the results.
