This Concrete Properties App provides you with a collection of concrete related calculations (one now, more following soon).

Currently we have included the calculations of the development of Ecm and fck for early age concrete. It shows the first 28 days of the hardening concrete.

The variables on which the calculations are based are the type of cement, the actual fck at the age of 28 days and the age of the concrete at t days.

Features
- US & in metric units.
- Graphs

More features we will provide in the future to our Concrete at early age Calculations:
- Export possibilities
- Anchorage length for rebars
- Concrete Quantities to determine the amount of concrete and reinforcement
