Abstract:
The author touches the high spots of development in the manufacture of concrete masonry units listing the many problems which now face the manufacturer. Rapid growth of the industry in the past ten years and the change from tamping to vibration methods is described. New plants are notable for labor saving equipment compared with those of the middle 1930's. In addition to block manufacture and several methods of curing, in use and proposed, the author mentions briefly: block-handling equipment, maintenance and repair of the plant, and the greater supervisory skill now required for sucessful operation.
