- measurement of heat of hydration according to ASTM C1702; - identification of potential incompatibilities of materials (between cement and impurities, etc.); - sulfate optimization; - sensitivity tests for changes in the content of impurities or other material; - assessment of compressive strength using heat of hydration curves; - determination of activation energy for prediction of thermal crack; -temperature sensitivity tests; - optimization of mix design and statistical analysis of effectiveness; - test temperatures above 50 °C (up to 70 °C), for example, for studies of delayed formation of etringitis; - characteristics of additional cement materials.

I-Cal 4000 HPC ("High Precision Calorimeter") is a 4-channel Isothermal Calorimeter. Like all Calmetrix I-Cal isothermal calorimeter models, I-Cal 4000 HPC features a sample size of up to 125ml, which can be used for multiple applications, including R&D and Investigative work on cement, mortar and concrete properties as well as daily QC needs in cement and concrete production. Variable reference cells make I-Cal 4000 HPC a versatile equipment, making it possible to test cement, mortar and real concrete, or other materials of various types and sample sizes. I-Cal 4000 HPC's tight temperature control is usitable for tests lasting up to 28 days. I-Cal 4000 HPC is fully compliant with ASTM C1679, ASTM C1702, ASTM C563 and EN 196-11. Field of Application: Cement and construction materials: hydration analysis and additive compatibility; Pharmaceuticals: drug stability and reaction with solvents; Polymeric systems: monitoring curing of resins and epoxies; Battery and electrochemistry: thermal behavior during charge/discharge cycles; Food industry: enzyme/starch reactions, energy value estimation; Scientific research: any thermally active process such as catalysis or bioreactions.

Study of cement hydration processes; Development of low-heat or fast-setting compositions; Optimization of concrete mix design for hot/cold climates; Compatibility studies of cements with various additives.
