  • Manufactured sand production MetsoCement Sand and Aggregate for Nominal Mix Concrete

    The workability of the final concrete mix and the amount of cement used are two of the most important parameters in concrete production These parameters in turn are mainly affected by the quality of sand used in the processNov 19 Concrete mix design is the process of economically proportioning of concrete ingredients cement sand and aggregate for better strength and durability based on the materials available at a construction site
