• The Nurse-Saul method which assumes that concrete strength development is a linear
function of hydration temperature.
• The Arrhenius method, which assumes that an exponential relationship exists between
compressive strength and hydration temperature.
The intelliRock III system supports both maturity methods. The project engineer should make
the decision about which method to use.
Temperature Profiling
Documenting the temperature profiles and gradients of in-place concrete is another applica-
tion of the intelliRock III system. The thermal data captured by intelliRock temperature loggers
is uninterruptible and unalterable, providing proof of the thermal integrity of a placement. Con-
crete temperature profiling with intelliRock is ideal for cold-weather pours, mass pours, curing
tanks, and moist rooms.
