Abstract:
The authors discuss the advantages of air entrainment with regard to durablity, permeablity, workablity, reduction in alkali expansion, time saving, reduction in water and cement, temperature rise, strength, abrasion resistance, monolithic lightweight concrete and mass concrete. U. S. Bureau of Reclamation experiences are discussed with regard to pumping, transportation and placing, grading of aggregates, factors affecting the amount of air entrained. Air-entraining agents and air-entraining cements are discussed briefly. There is a brief section on the measurements of entrained air in concrete with a recommended procedure.
