Design Procedure Concerning Composition of Composites Containing Gypsum-Free Cement

Peer-reviewed article not indexed in WoS or Scopus

Composites containing gypsum-free cement features quick strength rise at the age between 1 and 3 days. Such property predestine gypsum-free cement concrete for repair of building constructions that are to be put into service as soon as possible. Repair of concrete-cement pavements and surfaces of similar character belongs to one of field of gypsum-free cement concrete application. Materials of these constructions shall comply not only with required strength characteristics but also with needed durability. That is why resistance to alternate frost, thawing and chemical deicing substances is the principal property of GFC concrete surface. Properties of gypsum-free cement concrete – whether fresh or hardened – are mainly affected by following factors: properties of gypsum-free cement (fineness of grinding, quantity of admixtures controlling initial setting time, clinker chemical composition) as well as mineralogical and chemical composition of natural compact aggregates, and water-cement ratio. Factors listed above are to be taken into account also during design of gypsum-free cement concrete composition. This article deals with design procedure concerning composition of concrete containing gypsum-free cement considering its specificities.
