This specification covers aggregates used for masonry grout. Aggregates should consist of either natural or manufactured sand, used alone or in combination with course aggregates. The course aggregates should be made up of crushed stone, gravel, or processed air-cooled iron blast-furnace slag with suitable particle shapes. Both fine and course aggregates should meet the particle size requirements, contain the right amount of deleterious substances and pass the soundness tests. Fine aggregates should be free from injurious amounts of organic impurities.
WJE laboratories are accredited by ANAB (ISO/IEC 17025) to perform testing standard ASTM C404 for Aggregates for Masonry Grout.
