INFLUENCE OF THE SELECTED STARCH HYDROLYSATES ON THE RHEOLOGICAL PROPERTIES OF CEMENT PASTE

Keywords: dextrin, starch hydrolysate, rheology of cement paste, plastic viscosity, yield point
Abstract: The aim of the study was to evaluate the effect of starch hydrolysates on the rheological properties of the cement paste. The Portland cement CEM I 42.5N and five types of dextrins were investigated. The study was conducted at two different water to cement ratios, i.e. 0.4 and 0.5. Rheometer determined values of the viscosity and shear stress in the cement paste, depending on shear rate, were used to determine the plastic viscosity and yield stress slurries, which were calculated using the selected mathematical models. Evaluated starch derivatives were analyzed for their suitability as modifiers of rheological parameters. The study revealed that the addition of starch hydrolysate results in a significant reduction of yield stress slurries, which in turn can lead to concrete mix liquefaction and mixing water reduction.
