4C-Temp&Stress is a computational tool to calculate temperatures and stresses in hardening concrete structures.
By means of 4C-Temp&Stress the hardening period can be simulated on a pc in order to avoid or minimize early-age thermal cracking during the first few days after casting. The parameters affecting early-age cracking are the casting rate, formwork, insulation, cooling pipes, heating wires, ambient weather conditions, etc.
The results of a calculation may be presented as:
- Diagrams showing temperature, maturity, strength and stress as functions of time.
- Isocurves of temperature, maturity, strength and stress at a given time.

Since the mid-1990ies 4C-Temp&Stress has been used to document curing and early-age requirements on several large civil structures around the world, including:
- The Øresund Link between Denmark and Sweden.
- Copenhagen Metro, deep stations and shafts.
- Marmaray Railway crossing, Istanbul, Bosphorus Strait Turkey. Bored tunnel, cut and cover, deep stations, Gama-Nurol JV.
- Sitra bridges, Bahrain, Gamuda Berhad Contractors.
- Funder highway bridge, Denmark, Züblin - Dyvidag JV.
- Eurasia Tunnel, Istanbul, Turkey.
A new version of 4C-Temp&Stress, ver. 3.00 was released in April 2015. The new version of 4C-Temp&Stres is compatible with projects made in the old version.
