摘　　要：The properties of binary and ternary cement pastes containing glass powder (GP) were examined.Hydration at early age was evaluated using semi-adiabatic calorimetry and at late ages using non-evaporable water content and thermogravimetric analysis.The transport characteristic was assessed by measuring electrical resistivity.The binary paste with slag showed the highest hydration activity compared to the binary pastes with GP and fly ash (FA).The results indicated that the pozzolanic behavior of the binary paste with GP was less than that of the binary pastes with slag or FA at late ages.An increase in the electrical resistivity and compressive strength of the binary paste with GP compared to other modified pastes at late ages was observed.It was shown that GP tends to increase the drying shrinkage of the pastes.Temary pastes containing GP did not exhibit synergistic enhancements compared to the respective binary pastes.
