Conception of a new binder containing plaster and sulfoaluminate clinker Etude d'un liant à base de plâtre et de clinker sulfoalumineux

This study aimed to produce an economic and ecological building material respecting the quality and safety common standards. Large wealth of gypsum even naturally in the careers or through phosphate industry has got in Morocco. After dehydration of gypsum, we obtain the plaster. This material is broadly used in the construction industry. The plaster is characterized by its good fire resistance, soundproofing and insulation and its decorative virtues. However, the principal limit of this substance is its water -keeping behavior. In order to resolve this problem, this study is focused on the conception of a new binder containing plaster and sulfoaluminate clinker.The treatement of the subject is based on the execution of three experimental plans. We will be lead into analyzing the relevance of the preparation of gypsum or plaster mortar and appreciate the impact of the sulfoaluminate clinker on the plaster.The optimization of the formulations of concreate containing plaster (or gypsum) and sulfoaluminate clinker would be introducing a several challenges which may be at the origin in a new era in the fields of civil engineering.
