Microstructural, Mechanical and Physical Assessment of Portland Cement Concrete Pavement Modified by Sodium Acetate under Various Curing Conditions

Portland Cement Concrete (PCC) pavement was studied with incorporation of an environmentally friendly eco-additive, sodium acetate (C2H3NaO2). This additive added to PCC in three different percentages 2%, 4% and 6% binder weight. For a comprehensive elucidation the eco-additive on performance pavement, casted samples were cured environments, namely: water, outdoors pond water. Water absorption tests, flexural compressive strength tests after 7 28 days curing conducted results compared control without any addition acetate. Results demonstrated significant improvement impermeability, when concrete is water bath outdoors. However, no/little observed that Microstructural analysis treated by using scanning electron microscopy (SEM) illustrated strengthening effect provides pore structure pavement.
