    Influence Of Manufactured Sand Characteristics On Strength

    Highlights Manufactured sand characteristics have a great influence on pavement performances of concrete. Increasing rock microfines amount to 20 will increase strength and improve abrasion resistance of concrete. Sand with both large roughness and low crushing value is beneficial to enhance flexural strength and abrasion resistance. Concrete abrasion resistance has not relation with silicon
