ConcreteAI Thermal & Crack Simulation Tool

Built on internationally recognised methods and guidelines

About this tool

As concrete cures, cement hydration releases heat. In thick or restrained pours that heat can raise the core temperature well above the surface and surroundings, and the resulting thermal gradient — and the restraint against the concrete contracting as it cools back down — can crack the concrete before it has even reached full strength. Predicting that temperature rise and the resulting crack risk ahead of the pour lets a project choose a mix, formwork and curing regime that avoids it.

This tool helps construction projects and engineering professionals develop a stronger technical understanding of in-situ concrete performance. It supports proactive casting planning and mix design optimization, advocating a more rigorous, data-driven approach to concrete construction.

This free tool offers the quick 1D thermal, 3D thermal and crack calculators at a limited problem size. For larger analyses, saved projects, and a casting plan tailored to your project, get in touch at qingyang.chang@concreteai.io.

Validated against real site data

Checked against measured concrete pours, not just theory, so the results reflect how concrete behaves on site.

Built on recognised guidelines

Internationally recognised industry guidance for early-age concrete temperature and cracking.

Built by ConcreteAI

Developed by concrete engineering specialists focused on mass-concrete thermal performance.

1D Thermal suits walls and slabs where heat escapes mainly through one face; 3D Thermal covers pours where heat dissipates in every direction and edge cooling matters, such as pile caps and thick slabs; Elements models heat exchange between adjacent or sequentially cast pours; Adiabatic derives a mix's own temperature-rise curve from its binder content; and Crack estimates early-age thermal crack width and restraint risk from a temperature profile.
