The basic design for lightweight concrete is covered in Eurocode 2 Part 1-1, with section 11 having particular rules required for lightweight aggregate concretes. Concrete is considered to be lightweight is the density is not more than 2200kgm 3 the density of normal weight concrete is assumed to be between 2300kgm 3 and 2400kgm 3 and a ...
4. Manufacturing. The original granulometry of the PET aggregate was outside the limits established by ASTM C 33 ibid standard for the MAS taken into consideration therefore, the material needed to be crushed in order to meet the standard. Crushing took into account a ratio of 35 particles passing through the 9.5 mm 38 mesh, which made possible to comply with the standard.
