Abstract:

This research project was undertaken to strengthen the knowledge in this area. The specific objectives were: l. To study methods of test for determining the clay content of concrete aggregates. 2. To determine the effects of clay content on the strength, shrinkage, and durability of concrete. 3. To relate these effects of clay on the properties of concrete to results of tests for determining clay content of the aggregates. This research included a study of the existing test methods (sand equivalent and loss by decantation) used to detect clay in concrete aggregates, and a study of the effect of various amounts of clay with various liquid limits on the strength, shrinkage, and freeze-thaw durability of concrete. The work necessarily included the determination of clay fraction properties of concrete aggregates from pits within the state of Texas. The concrete testing program included one basic mix design with two coarse aggregates; a siliceous river gravel (all except B series mixes) and a crushed limestone (B series mixes). A siliceous river sand and one brand of Type I cement were used throughout the program.
