摘要：

The present paper brings its contribution to the investigation on the use of a new binder, in the form of anhydrous calcium sulphate, as partial replacement of the ordinary Portland cement in concrete. The eco-binder is obtained exclusively from industrial wastes and can be entirely recycled after its expiration date. The results obtained so far show a decrease in the flexural and compressive strengths of mortars with small replacing percentages of anhydrous calcium sulphate. However, the flexural strength increases tremendously for higher percentages of anhydrous calcium sulphate. Slight gains in the values of the compressive strength were also observed for the considered specimens. (C) 2011 Published by Elsevier Ltd. Selection and/or peer-review under responsibility of APAAS
