PAVEMENTS Production of Roller-Compacted Concrete

Proportioning methods that use concrete consistency tests normally require the establishment of specific mixture parameters–such as the amount of aggregate, the amount of water, or the amount of cementi-tious materials–and then adjust one of these parameters in order to meet a required level of consistency, workability, or strength.

Manufacturing Light Concrete with PET Aggregate

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 (3/8′′) mesh, which made possible to comply with the standard.
