TAILIEUCHUNG - Effect of cellulose ether as a thickening agent on the adhesive and rheological properties of mortars

This paper presents an experimental study of adhesive and rheological properties of cement mortars proportioned with various contents of a water-soluble polymer admixture. To determine the adhesive properties the probe tack test was used. The results have been exploited to identify the adhesion strength, the cohesion strength and the support’ adherence force. It is found that the cohesion component displays a minimum when varying the polymer content. The behavior of the adherence force is more complex. The evolution of the adhesive force versus polymer content displays optima depending upon the tack test velocity. The rheological behavior of the mortars was also considered. | Effect of cellulose ether as a thickening agent on the adhesive and rheological properties of mortars Tạp chí Khoa học và Công nghệ 52 (2) (2014) 203-212 EFFECT OF CELLULOSE ETHER AS A THICKENING AGENT ON THE ADHESIVE AND RHEOLOGICAL PROPERTIES OF MORTARS Phan Van Tien* Faculty of Construction, Vinh University, 182 Le Duan Str., Vinh city, Vietnam * Email: vantienkxd@ Received: 03 November 2013; Accepted for publication: 11 January 2014 ABSTRACT This paper presents an experimental study of adhesive and rheological properties of cement mortars proportioned with various contents of a water-soluble polymer admixture.

INTRODUCTION A number of studies have been reported in the literature concerning the influence of water- soluble polymers on the rheological behaviour of cement pastes [1, 2], mortars [3, 4] or concretes [5, 6]. Most of these studies reported a monotonic increase of the yield stress and plastic viscosity of the material when the admixture content was increased. However, in the particular case of mortars, it has been reported that the two rheological parameters displayed a minimum when the polymer content was increased [3]. This has been attributed to the competition between the thickening effects of the polymer, which is expected to lead to an increase of the yield stress and plastic .
