Abstract

A high speed method of thermal anal. 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 DegC, of lime/sand mixts. of different proportions was related to the known quantity of lime in each mixt. It was shown that a heating rate of 50 DegC min-1 produced data which had a very high correlation with known quantities of Ca(OH)2. This method can be used to measure the extent of carbonation at varying depths through a lime mortar. This can be repeated at intervals to give an insight into the shape and extent of the carbonation front as it develops over time. [on SciFinder (R)]
