Title: Plant Drying and Carbonation of Concrete Block-NCMA-PCA Cooperative Program
Author(s): Henry T. Toennies and Joseph J. Shideoer
Publication: Journal Proceedings
Appears on pages(s): 617-634
Abstract:Previous studies have shown the effectiveness of treatment by carbon dioxide gas in improving the volume stability of concrete block and brick. Several products plants have installed equipment for drying and carbonation by combustion gases. An investigation was undertaken to evaluate various methods under plant operating conditions. The more effective treatments reduced greatly the potential shrinkage of the concrete units, while others were totally ineffective. Conclusions were reached regarding kiln con-ditions necessary for effective treatment. The protect was a cooperative one between the National Concrete Masonry Association, the Portland Cement Association, and five concrete products plants.
