Lehigh White Cement is promoting two formulations from the Aalborg InWhite Solution family of pre-mixed, ultra-high performance concrete materials developed by parent company, Cementir Group of Italy. Aalborg Excel and Aalborg Extreme are self-levelling, fast flowing mortars, conducive to pigment and fiber combinations and achieving very smooth surface finishes. Flowability, extended set time and durability characteristics, plus compressive strength in the range of 17,000 psi to 20,000 psi, make the materials well suited to architectural concrete with thin and complex geometries.
Excel and Extreme are shipped in 25-kg (55-lb.) bags and contain white portland cement from Lehigh’s Denmark sister company, Aalborg Portland A/S. The materials are based on Futurecem, Cementir’s proprietary binder technology. Free of silica fume, quartz flour, slag or fly ash, Futurecem embodies “highly advantageous pozzolanic components from a sustainable source,” Cementir officials note. “By adding different types of fibers and pigments, both UHPC products can help achieve the integration of structure, function and aesthetics.” — www.lehighwhitecement.com
