ULTRACEM®
is a fast setting and drying Portlandcement with an extreme high early strength. The cement is used in dry-mixed mortars, and concrete where acceleration and quick re-installment is required . Contrary to other quick setting Portlandcement ULTRACEM® is Fluor free and poses no threat to human or animal health. Chrome VI content is well below the set limit of 2 ppm. All known organic additives i.e. plasticizing- and air-entraining agent, retarder etc. used for Portlandcement can also be added.
compressive strength 3 hours ≥ 10 Mpa 28 days ≥ 60 Mpa
initial set
≤ 3 ~ 5 min. loss of ignition
≤ 5 %
sulfate content
≤ 8 % chloride
≤ 0,1 %
expansion
≤ 0,02 mm/m ULTRACEM® is used as regular cement binder, and can be introduced in a cement matrix, mixed with different types and size of aggregate. Because of its fast setting and the possible interaction with other components pre-use testing is obligatory! A higher w/c ratio increases the porosity, leading to reduction in strength of hardened concrete and mortar. ULTRACEM® is especially used at low ambient temperature concrete and mortar, and rapid repair work. ULTRACEM® releases alkali and should be treated and handled as any other cement. All safety measures are applicable. Consult our Material Safety Data Sheet. ULTRACEM® is delivered in bulk , big-bags 1,250 to. and small bags of 25 kg. on pallets. Stored dry the cement should be used within 3 months after production date - longer storage and high humidity may retard the setting and have an impact on the strength development.
