Abstract:Describes tests employed and results obtained in an investigation of properties of lightweight-aggregate concrete of structural quality. Eight lightweight aggregates and one normal weight sand-and-gravel aggregate are included. The total program includes tests of plain, conventionally reinforced, and prestressed concrete specimens, but except for pull-out tests of reinforcing bars, only the data on plain concrete are given. Data are reported on concrete mix proportions, compressive and flexural strength, modulus of elasticity, bond, creep, and drying shrinkage. Concrete mixes were designed to produce compressive strengths of 3000 psi and 4500 psi with each aggregate, and 7000 to 10,000 psi with three selected aggregates. Comparing the various concretes on the basis of equal compressive strengths, normal weight sand-and-gravel concrete showed somewhat superior performance in most tests. In many structural applications, however, this superiority will doubtless be overshadowed by advantages resulting from reduced unit weight of the lightweight-aggregate concretes.
