A lightweight aggregate concrete mix is required to test
4,000 psi at 28 days. It is to have 51{12% air entrainment and 41{12 in. of
slump. The coarse aggregate has a dry unit weight of 50 lb/cu ft, moisture
content of 3%, maximum size of ¾ in., and a specific gravity of 1.35. Fine
aggregate has a dry unit weight of 65 lb/cu ft, free moisture content of 6%,
and a specific gravity of 1.90. Calculate the weight of materials required for
a 2 cu ft trial batch, using middle-range cement content.
