I-Cal Strength

Long desired and awaited by the Industry, the CalCommander I-Cal Strength software module lets you predict compressive strength development of a given mix using an isothermal calorimeter.

I-Cal strength is based on the correlation between the energy released (degree of hydration) and the compressive strength development of a mix.

CalCommander will guide you to establish a Correlation Model for each mix design you would ike to use to infer compressive strength predictions. A mix design is defined by its binder, water, air and sand types and contents, as well as the mixing method used. If any of the aforementioned parameters changes, a new Correlation Model has to be built. Minor changes of dosages or types of chemical additives do not require a different Correlation model.

Here's how it works:

Now you can use your Correlation Model to make strength predictions for your mix.

Once you built a correlation model for a mix, all you need to do the next time you are batching this mix is a calorimeter curve. You avoid costly and time-consuming laboratory testing, and you don't have to wait to reach a curing age to get a compressive strength estimate. A calorimetry curve will be enough to give you estimates of compressive strength at different curing ages.
