—In Brazil, the gypsum plaster waste is 4% to
15% of construction and demolition waste. The
environmental legislation advises that this waste should be
recycled to avoid the contamination of soil and groundwater.
The aim of this work is to show that the recycled gypsum
plaster maintains its characteristics when submitted to
different recycling cycles. The recycled gypsum plasters were
produced by grinding and burning the waste along three
successive recycling cycles. The recycled materials were
evaluated by chemical and physical properties. The obtained
results showed that both recycled and commercial gypsum
plaster are similar to using in the Construction Industry.
