The main objective of the study is focused in
\r\nproducing slag based geopolymer concrete obtained with the addition
\r\nof alkali activator. Test results indicated that the reaction of silicates
\r\nin slag is based on the reaction potential of sodium hydroxide and the
\r\nformation of alumino-silicates. The study also comprises on the
\r\nevaluation of the efficiency of polymer reaction in terms of the
\r\nstrength gain properties for different geopolymer mixtures.
\r\nGeopolymer mixture proportions were designed for different binder
\r\nto total aggregate ratio (0.3 & 0.45) and fine to coarse aggregate ratio
\r\n(0.4 & 0.8). Geopolymer concrete specimens casted with normal
\r\ncuring conditions reported a maximum 28 days compressive strength
\r\nof 54.75 MPa. The addition of glued steel fibres at 1.0% Vf in
\r\ngeopolymer concrete showed reasonable improvements on the
\r\ncompressive strength, split tensile strength and flexural properties of
\r\ndifferent geopolymer mixtures. Further, comparative assessment was
\r\nmade for different geopolymer mixtures and the reinforcing effects of
\r\nsteel fibres were investigated in different concrete matrix.<\/p>\r\n","references":"[1] J.
