Abstract

This paper describes the rheological parameters and the fluidity of mixes containing viscosity enhancing admixture (VEA) diutan gum and compare it to welan gum. This investigation was undertaken to evaluate the influence of the dosages of diutan gum and the superplasticizer (SP) on fresh properties of cement-based materials paste with 0.40 water-tobinder ratio (W/B). The fresh properties of reference grouts made without any VEA and with SP were compared to those of mixes made with 0.02%, 0.04%, 0.06%, 0.08%, and 0.10% diutan gum by mass of cement. The effect of replacement of cement by sustainable byproduct such as ground granulated blast slag (GGBS) at 20%, 30% and 40% was also investigated with different various dosages of diutan gum. The results indicate that for any given dosage of SP, the increase in the dosages of diutan and welan gum led to an increase in yield stress, apparent and plastic viscosities, and to a reduction of fluidity.
