Calcium sulfoaluminate (CSA) cement and ordinary Portland cement (OPC) blends are innovative binders. In comparison with OPC, these mixtures can reduce the environmental impact of cement production as well as increase the hardening speed. This article deals with the effects of calcium sulfate (anhydrite) percentage on hydration mechanisms, compressive strength and dimensional stability of binders containing 40% OPC. Calcium sulfate quantity is an essential parameter that can be used to control the hardening speed and dimensional stability. Mortars with 6 . 5% and 10% anhydrite present moderate compressive strength and expansion, whereas higher compressive strength and expansion are obtained with blends containing 17% and 20 . 5% anhydrite. These anhydrite proportions slow down the OPC and CSA clinker hydration kinetics but increase the ettringite proportion and stability.

Purpose This research aims to explore the impact of an overlooked variable, brand typicality, on brand evaluation and the categorization of counterfeits and imitations. Design/methodology/approach The research design is a 2 × 2 × 2 × 2 mixed design with the first three variables as between-subjects variables and the last as a within-subjects variable on a convenience sample of 287 respondents split into eight experimental conditions. Data are analyzed using Linear Mixed Models. Findings Results show that brand typicality and brand name and product appearance manipulations impact brand evaluation and categorization. Regarding brand evaluation, under high typicality conditions, any manipulation of brand name and/or product appearance, from identical to different, results in a less favorable evaluation, whereas under low typicality conditions, only brand name manipulation negatively impacts brand evaluation. Concerning categorization, under high typicality conditions, any change in brand name and/or product appearance results in the item’s categorization as an imitation or a counterfeit, whereas under low typicality conditions, the item may be categorized as either genuine or as imitation or counterfeit. Originality/value This research demonstrates the impact of brand typicality on both the evaluation and categorization of changes in brand name and product appearance. It also suggests that brands and product classes are not equal vis-à-vis counterfeiting and imitation. High typicality brand seems less vulnerable to counterfeiting and imitation. Findings are discussed regarding brand vulnerability to imitation and counterfeiting, the importance of considering competitive context, brand management and brand strategy.
