Abstract

The formation of Ettringite after the hardening of cement minerals is accompanied by extra gypsum, which may lower the intrinsic strength of calcium silicate hydrate due to the presence of sulfate ions in its structure. The important factors influencing the resistance of concrete against internal sulfate attack are the chemical reactions between sulfate ions contained in the mixing water or extra gypsum and the minerals of cement during its hydration and the concentration of the reactant concerned in the pore solution. The main purpose of this research is to study experimentally the possibility of producing effective and economic admixtures from sugar industry wastes (Vinasse) and mix it with sodium naphthalene formaldehyde to produce (VSW 2016) additive. Then study of its effect on the compressive, tensile strengths and durability parameters represented in permeability, chemical attack and different cycles of durability are illustrated. Test investigations, show that, a limited dose of the (VSW 2016) in the mixing water of concrete mixture regulates its micro structures formation and improves the durability parameters in aggressive environment compared to the control specimens.
