Effect of temperature on the rheology of flowable mortars

Influence of superplasticizer, temperature, resting time and injection pressure on hydraulic lime grout injectability. Correlation analysis between fresh grout parameters and grout injectability

“…8, it is clear that the rheology of a grout suspension strongly depends on temperature and resting times. As observed by Petit [36] there are changes in rheological properties for different temperatures and resting times, which are related to the evolution of the restructuring of the microstructure, binder hydration, interaction between binder and superplasticizer and variation of free water content.…”

“…This SP belongs to the third generation whose repulsion is a combination of coupled steric and electrostatic effects, known as electrosteric [36,38]. Due to the dispersion action, the particles remain far enough so that they cannot come together, i.e.…”

Structure and Characterization of Sulfated Chitosan Superplasticizer

“…Superplasticizers (SPs) are the most important concrete admixture because they may endow fresh concrete with high fluidity at a low water to cement ratio (w/c) and can remarkably improve the mechanical properties of concrete . Therefore, SPs have always been the research hotspot from its birth to the present.…”

Thixotropic behavior of cement-based materials: effect of clay and cement types

“…However, the efficiency of such combination also depends on the temperature of the mixture. Petit [9] investigated the effects time and temperature have on yield stress and plastic viscosity of mortar mixtures obtained from SCC with addition of High Range Water Reducing Agents. He also developed general equations in order to indicate the relationship between temperature/time with yield stress and viscosity, which were very useful to predict the rheological parameters for concrete.…”
