Polystyrene beads |
| abstract |
Substantially cylindrical unexpanded polystyrene beads with a diameter on the order of 1 mm and a length on the order of 3 mm are expanded into substantially cylindrical expanded polystyrene beads with a diameter between about 2 and 5 mm, and a length between about 4 and 10 mm. These expanded beads are well suited for use as a substitute for concrete aggregate to make lightweight concrete and concrete construction boards. |
