This work has been done in order to valorize starch in industrial mortars. Its effect on cement hydration has been studied to propose the mechanism of interaction. After the characterization of raw materials, the study of cement hydration in dilute environment (W/C=20) enables us to propose mechanisms between polysaccharides and cement. Electrical conductivity measurement combined with the pH one and ion chromatography revealed that in the cement environment, the dextrose and the heated native cassava starch disrupt release of sulfate ions and consumption of calcium ions by adsorbing on first hydrates, slowing or blocking then the hydration of cement.
