The Effect of Glucose on the Properties of Cement Paste

Abstract

This study presents the results of an investigation of the effect of glucose on the hydration, microstructure, and properties of cement pastes. The hydration was studied using non-evaporable water content measurement and thermogravimetric analysis (TGA). Electrical resistivity as a measure of the transport property of cement pastes was evaluated using electrochemical impedance spectroscopy (EIS). It was found that all cement pastes showed a similar degree of hydration at late ages. The cement paste with a low concentration of glucose (0.05%) showed a slightly higher compressive strength and electrical resistivity compared to the control cement paste. This was most likely due to improved workability and dispersion of cement particles in this cement paste. However, the cement paste with 0.25% glucose showed a lower electrical resistivity compared to the control cement paste.
