ABSTRACT. The effects of stone powder content and particle size range of machine-made granite sand, limestone crushed machine-made stone sand, and limestone pebble machine-made sand on MB value and mortar fluidity are compared and studied. It is found that the MB value of granite machine-made sand remains unchanged with the increase of stone
