Abstract:
Reports a study of cinder aggregates designed to determine the cause of strains and pop-outs in cinder concrete and to develop methods of cinder treat- ment to eliminate trouble from these sources. The causes are identified, a simple method is described for detecting the presence in cinders of the impuri- ties causing stains and some classes of pop-outs, and at least two practicable methods are presented for cinder treatment. Correlation between laboratory tests and field performance of concrete masonry units is shown and a specification is suggested to minimize the occurrence of stains and pop-outs.
