Abstract

A high speed method of thermal analysis was developed to allow the carbonation profile of lime mortars to be followed within a convenient time-frame. The loss in mass on heating, up to 700°C, of lime/sand mixtures of different proportions was related to the known quantity of lime in each mixture. It was shown that a heating rate of 50°C min produced data which had a very high correlation with known quantities of Ca(OH) . Thismethod can be used to measure the extent of carbonation at varying depths through a limemortar. This can be repeated at intervals to give an insight into the shape and extent of the carbonation front as it develops over time. © 2006 Akadémiai Kiadó, Budapest.
