CARBONATION PROGRESS OF ACTUAL RC BUILDINGS COVERED WITH OUTSIDE FINISHING MORTAR

Abstract

We have investigated three actual RC buildings, which were built about 50 years ago, to clarify the carbonation inhabitation effect of the finishing mortar on the progress of concrete carbonation. It is found from this investigation that the differences of carbonation progress between the concrete outside wall in one orientation and that in other orientations can be evaluated in carbonation rate coefficient. The investigation of durability of other actual RC buildings should become more accurate with the simplified analytical method described in this paper.
