ULTRACEM® is a fast setting Portland cement that achieves high early strength within 3 hours and compressive strength of over 10 MPa. It sets within 3-5 minutes and contains less than 5% loss of ignition and 8% sulfate. ULTRACEM® can be used in dry-mixed mortars and concrete where quick re-installation is required, such as in low temperature environments and for rapid repair work. Safety precautions should be followed when using ULTRACEM® due to its fast setting properties.

1. 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.
