The influence of composition on thixotropic behaviour of cement mortar

This paper presents methods of measurement and results of rheological properties including the thixitropic stiffening of designed cement mortars. The aim of the study is to determine the effect of the type of cement, w/c ratio, and chemical admixtures on the selected rheological properties of mortars. It will allow a better understanding of the nature of previously observed decreasing formwork pressure when using self-compacting concrete.The research was financed by the project No. 0842/B/T02/2011/40 from the National Science Centre and the project “DoktoRIS – Scholarship program for innovative Silesia” co- nanced by the European Union under the European Social Fund
