| Summary: | Waste glass and reclaimed brick are types of construction and demolition
waste (C&DW) that could potentially be used as secondary raw materials in
the production of ceramics. Ceramics based on clay, waste demolished brick
(5-15 wt.%) and waste glass (5-20 wt.%) were produced by pressing (P = 68
MPa) and subsequently sintered at 900, 950, 1000, and 1050 oC for one hour.
The physical and mechanical properties of the ceramics obtained were
evaluated. The addition of demolished brick decreased the density and
mechanical properties of the clay specimens and increased the water
absorption. The incorporation of waste glass improved the sintering behavior
and its mechanical properties. The addition of 20 wt.% waste glass and 10
wt.% waste demolished brick into the clay matrix improved the flexural
strength by up to 20.6 % and decreased the water absorption by up to 22 %.
The approach presented promotes an opportunity to recycle construction and
demolition waste into alternative resource materials, and represents a
positive contribution to the environment. |
