文摘

Flue gas desulfurization (FGD) gypsum and textile fibers constitute two large-scale industrial wastes generated in China. In this work, these wastes were used for making foamed concrete which can increase the energy efficiency of buildings. The effects of the W/S ratio, super plasticizer amount, foaming agent as well as textile fibers contents on the compressive strength and density values of the porous FGD gypsum plaster materials was systematically investigated. The highest compressive strength value of the gypsum blocks was 1.6 MPa after 7 days of curing, and the measured density value was 617 kg/m3. The obtained results suggest an effective way to recycle FGD gypsum and textile fiber wastes in order to produce not only low-cost and effective buildings materials, but also to lessen the environmental impact.
