Abstract
The process is for the use of slurry generated in the filtration and treatment of water for human consumption for formulating expanded clay. The correct control of the filtration and treatment processes ensures reasonable constancy of properties in terms of chemical composition and granulometric distribution (generally below 0.2 mm). The slurry has a level of humidity greater than 50 per cent, which is virtually totally removed by driving, enabling it to be used as required and processed. Formulations have been tested using slurry up to 25 per cent by weight. Addition was made by substitution of paste as an entity. Maintaining manufacturing conditions unaltered, products are obtained with functional properties similar to their congeners without addition of residue.
