Some more input from CalStar on their pending entry into the building materials market. I had asked about who set the standards for what is a “brick.”
The answer from CalStar: “ASTM is not the gatekeeper for new products – national and local building codes are. As with any new building material, we need to start with the standards that are available for similar products, and then develop a suitable ASTM standard for fly ash brick in due course. Despite what the BIA may try to make people believe, there’s no particular magic here – the ASTM standards that test the suitability in real live applications for concrete products, clay bricks, and other masonry products are remarkably similar despite the fact they’re made of different raw materials.
