A GUIDE TO DETERMINING THE OPTIMAL GRADATION .
The proportioning of sand and coarse aggregate components has an important effect on 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....
