Characteristics of Gypsum Recycling in Different Cycles

Sayonara M. M. Pinheiro and Gladis Camarini

Abstract—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.

Index Terms—Gypsum plaster, physical properties, recycling, waste.
