Determining water absorption of coarse lightweight aggregates for concrete
Methods of test for water absorption and bulk specific gravity of aggregates were used on small samples of 15 light weight aggregates; loss of pore water due to prolonged surface drying by towel, and phenomena in vesicular, open pore materials when mixed in paste or concrete were studied; technique developed for determining amount of absorbed water in aggregate particle after mixing in miniature batch of concrete was used to evaluate current methods for determining absorption of light weight coarse aggregates.
