摘要：

Simultaneous DTA-TG and derivative thermogravimetry, DTG, have been employed to evaluate autoclaved cement : quartz pastes, before and after carbonation. DTG curves provided more detailed information about mass loss phenomena than the corresponding TG curves. Results indicated that the dynamic method did not allow sufficient time for reactions to be completed. Data obtained from dynamic methods can be used to carry out semi-isothermal thermogravimetry very successfully, the latter allowing separation of peaks due to overlapping decomposition phenomena.
