Intelligent Formwork > What do we measure?
Nonstop measurement of
in-place strength gain
Temperature evolution <>
Thermal stresses
Initial setting, Initial stiffness
Fair-faced grey- or color tone

The maturity method uses the fundamental concept
that concrete material properties develop with time as
the cement hydrates and releases heat, allowing
sensors to measure “Nonstop compressive strength
gain”.
A very accurate and reliable method.
CONCREMOTE uses maturity method
The maturity method has been developed, validated
and included in many leading standards worldwide
since 1982.
British
Standard
European
Standard
ASTM Standard

Measure inside concrete structure more reliable than test specimens
CONCREMOTE Intelligent Formwork
• Inside concrete structure/element.
• Continuous information on actual
strength gain
• Sensor positions at critical locations
• Lab/field cured test specimens do not
replicate the same temperature profile as
the in-place concrete and consequently
do not measure its in-place strength as
accurately.
• Curing temperature profile visible
• No validation if test specimens are
compacted similar to in-place concrete.
• Not depending on 1 specimen test result
