• Abstract:

  Cost consciousness and a desire to utilize new designs has stimulated builders’ interest in lightweight structural concrete. This, in turn, has stimulated an increase in the supply of expanded clay, slate, shale and slag aggregates used to produce such concrete. In 1959 about 4 million tons of expanded shale, clay, and slate aggregates and about 3 million tons of expanded slag aggregates were marketed. Thirty percent of the production of expanded clay, shale, and slate, and around 5 percent of the expanded slag aggregates was used in structural cast-in-place concrete.As those who have used it know, lightweight concrete effects considerable savings in building steel and deadweight, and, in many cases, makes possible the addition of several stories without radically altering basic plans.
