CARBONATION OF GROUTED CONCRETE MASONRY

Abstract

This paper deals with three series of experiments for clarifying the general tendencies in carbonation of concrete masonry of which units are produced by vibrio-pressing methods, and a proposal on the methods for predicting carbonation depth in building components made of grouted concrete masonry. Various grades in characterized compressive strength of concrete masonry units were experimented to clarify tendencies in the carbonation processes under an accelerated condition in order to propose the both equations for predicting carbonation coefficient of concrete masonry units and carbonation processes in grouts through faceshells of these units.
