Lightweight Aggregates

Source

Lightweight mineral aggregates as discussed herein are those used in the manufacture of portland-cement concrete having a unit weight less than about 120 lb. per cu. ft. Air-cooled blast-furnace slag is excluded, not only because it produces concretes of unit weight greater than about 130 lb. per cu. ft. but also because it is specified and used in the same manner as ordinary crushed-stone aggregates. Certain aggregates of extremely limited use or which have only been produced experimentally are not included in the present discussion. Acknowledgment is hereby made to the many experimenters whose data, together with personal observations of the authors, form the basis for this discussion. Lack of space prevents listing all of these in the appended bibliography.
