    Gradation of Aggregates and its importance in Mix Designing

    Concrete mix designing is a vital part of any construction activity. Why we do mix design when proportions for material are listed in IS codes for various grades? The listed mixes have more cement content than required and have fix properties like workability, retention time etc. In order to...

    CONCRETE AGGREGATE

    Gravels, stone and sands form the granular structure, which must have its voids filled as completely as possible by the binder glue. They makeup approximately 80 % of the weight and 70–75% of the volume. Optimum use of the aggregate size and quality improves the concrete quality. Aggregates can...
