Styrofoam as partial substitution of fine aggregate in lightweight concrete bricks [PDF]
AIP Conference Proceedings, 2018 A development of concrete brick technology leads to some innovations in this field. To produce lightweight concrete brick, lightweight aggregates such as Styrofoam, pumice stone and perlite, are required. The use of lightweight material is beneficial to reduce the weight of the concrete.

Use of Sewage Sludge for the Substitution of Fine Aggregates for Concrete
Journal of Composites Science, 2023 This work analyzes the use of sewage sludge, generated in wastewater treatment plants, as an alternative for small aggregate to be used in concrete. Concrete cylindrical specimens with height h = 20 cm and diameter D = 10 cm were prepared using different amounts of sludge in the substitution of fine aggregates.
