The software analyses the potential drying shrinkage cracking in concrete slabs, comparing the evaporation rate vs the bleeding rate for various thicknesses and compression strength.For the calculation of the evaporation rate, uses the climatic parameters of darksky.net service database, in the location detected by the GPS of the device where it is installed. It also allows the user to manually enter the location.The software establishes the potential for LOW, MODERATE, HIGH or CRITICAL cracking, depending on the magnitude of the evaporation rate that exceedsthe bleeding rate.
