refinement process appears to wind up at 14 days, which in turn shows a maximum relative strength and a minimal rise in the total pore volume along with the CH level. Palomo et al. [ 46 ] studied the alkali activation of MK and it is with the aggressive

the higher resistance of aggressive ions into the concrete. After 28 days of curing the test specimens were oven-dried for 24 hours at 105  °C and the constant mass was ensured by weighing. Apart from the bottom surface, all sides of the specimens were

-to-weight ratio of FRP reinforcement provide a perfect solution for optimized structures in aggressive environments. However, a drawback is its low modulus of elasticity compared to steel which results in early concrete cracking at lower service loads [ 1 ], as

, causing weakness points in the slab and reducing its overall resistance to the external loads. The formation of the cracks weakens the concrete ability to resist aggressive substance, also will expose the reinforcement bars to the risk of corrosion [ 4
