The Concrete Maturity Method (ASTM C1074)

Monitor in-place strength in real-time via embedded temperature sensors.

Key Benefits

Accurate estimation of in-place strength
Reduced reliance on cylinder breaks
Earlier form removal & faster cycling
Cost control through data-driven decisions

How it works

A temperature sensor is embedded during placement, continuously recording data to estimate strength development. This supports critical sequencing decisions with real data.
