Influence of the MB Value of Manufactured Sand on

In this paper, influence of micro-fines on the manufactured sand and influence of manufactured sand containing micro-fines on concrete is studied. Using the MB value of manufactured sand to control the content of micro-fines in manufactured sand. The experimental results show that if MB value is less than 1.0, content of micro-fines is less than 15%, concrete keeps a high level of compressive

2011-10-1 · 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
