The I-Cal 8000 is an Isothermal Calorimeter that can be used to test cement paste, mortar or even real concrete. A thermal hydration curve is plotted as the ambient temperature around the sample is kept constant. The temperature is easily set on a digital display placed on the equipment, while precision sensors measure the heat flow generated by the early hydration reaction of concrete.

Data generated by I-Cal is retrieved and analyzed with Calmetrixʼ state-of-the art CalCommander software, which combines ease of use and a suite of analytical tools.

I-Cal 8000 is cost effective, yet precise enough for applications in multiple fields, including R&D and Investigative work on concrete properties, and daily QC needs in Cement and Concrete production. It is typically used to perform the following tasks:
• troubleshooting complex mixes with multiple admixture interactions - detect potential material incompatibility
• sensitivity tests on small variations in admixture or other material content
•determination of activation energy for thermal crack prediction (requires additional software)
• rapid screening of materials, e.g. different sources of cement, different brands of admixtures
• sensitivity tests on temperature variations
• mix design optimization and statistical performance analysis

Users of Isothermal Calorimetry can be found in Universities, Cement Producers, Concrete Producers, Fly Ash Distributors and Testing Laboratories.
