GRADATION OF AGGREGATE FOR CONCRETE BLOCK

1. Strength—The influence of aggregate gradation on the compressive strength of finished concrete block will determine the necessary cement content to produce block which meet specified strength requirements. Since cement is the most costly ingredient in the concrete mix, the selection of a properly graded aggregate assumes an economic aspect. 2.

the properties of both the fresh and hardened concrete. Unsatisfactory gradation may lead to: 1. Segregation of the mortar from the coarse aggregates. 2. Bleeding of water below and around larger aggregates and on the surface of the concrete. 3. Settling of aggregates, leaving paste in the top layer of the concrete.
