    Crushed stone powder can be a promising material used for the purpose of increasing the qualities of concrete. Such crushed stone powder is limited to what passes through a 150-micrometer sieve in which the by-product is separated and/or ground at the time of manufacturing of a crushed stone and/or a crushed sand by dry process in the plant. Actual quality conditions studies of crushed stone powder and raw crushed stone powder are reported in which studies items are moisture content, density, percent flow, activity index, 75-micrometer sieve remains ratio and Methylene Blue absorption specified in TR A 0015 (Crushed stone powder for concrete). The quality of crushed stone powder is proposed in the first JIS A 5041 (Crushed stone powder for concrete) which was published at Spring of 2009 after withdrawal of TR A 0015.
