Effect of High Molecular weight Cellulose Ethers on the Resistance in Shearing of Fresh Mortars
Journal Title: Scholars Journal of Engineering and Technology - Year 2017, Vol 5, Issue 12
Abstract
This paper presents an experimental study on the effect of three types of water-soluble high molecular weight polymers on the resistance in shear of cement mortars in fresh state. The role of molecular weight of cellulose ethers in modifying the yield strength of mortars in shear have also been investigated. To determine the rheological properties the Vane-Cylinder test was used. Hershel Bulkley model has been used to determine the rheological parameters, including yield stress. It is found that at low shear rates, all the mortar mixes behaved as a shear-thinning fluid. However at high shear rates, we observed a difference between the mixes corresponding to the different cellulose ethers. The investigation of the influence of molecular weight on the properties of fresh mortars has shown a similar observation to the reported research in literature. The yield stress of the mortar decreases with the increase of molecular weight. This decrease is not significant at low molecular weights, and becomes much more significant at high molecular weights.
