Are there ASTM standards for fly ash bricks and pavers?
There are not yet ASTM standards specifically for fly ash bricks or fly ash pavers. However, CalStar products meet the performance requirements of the corresponding clay and concrete brick and paver specifications (ASTM C216 – 07a Standard Specification for Facing Brick (Solid Masonry Units Made from Clay or Shale), C1364 – 09 Standard Specification for Concrete Facing Brick, C902 – 09 Standard Specification for Pedestrian and Light Traffic Paving Brick, C936/C936M – 09 Standard Specification for Solid Concrete Interlocking Paving Units).
