The I-Cal 2000 HPC (High Precision Calorimeter) is a 2-channel isothermal calorimeter. Like all Calmetrix I-Cal isothermal calorimeter models, the I-Cal 2000 HPC has a sample size of up to 125 ml, which can be used for applications in many industries, including research and concrete property studies, as well as daily quality control needs in cement and concrete production. Interchangeable reference cells make the I-Cal 2000 HPC a versatile instrument that allows you to test cement, mortar and real concrete or other materials of different types and sizes of samples.
The I-Cal 2000 HPC is suitable for long-term cement hydration testing up to 28 days or longer.
In addition, I-Cal 2000 HPC fully complies with ASTM C1679, ASTM C1702, ASTM C563 and EN 196-11.
As with other Calmetrix I-Cal calorimeters, the ambient temperature around the samples is controlled by a computer via the Calmetrix software interface, using precise sensors that measure the heat flow generated by the cement hydration reaction. But the I-Cal 2000 HPC stands out with its intelligent design that minimizes sensitivity to external conditions. This means more consistent results, as well as reliable performance even in unconditioned environments, a clear advantage in terms of reproducibility and cost savings for field laboratories or non-conditioned facilities. In addition, the two active sample cells of the I-Cal 2000 HPC do not contact each other, thus keeping crosstalk below 0.1%.
Application:
The I-Cal 2000 HPC is well suited for applications in research and development of cement and concrete properties, as well as for daily quality control needs in cement and concrete production. Typical uses:
• measurement of heat of hydration according to ASTM C1702
• identification of potential material incompatibility (between cement and admixtures, etc.)
• sulfate optimization
• tests for sensitivity to changes in impurity content or other material
• evaluation of compressive strength using heat of hydration curves
• determining the activation energy for predicting thermal cracking
• tests for sensitivity to temperature fluctuations
• mixture design optimization and statistical analysis of efficiency
• test temperatures above 50 °C (up to 70 °C), e.g. for studies of delayed ettringite formation
• characteristics of additional cement materials
When to consider I-Cal 2000 HPC:
I-Cal 2000 HPC — correct isothermal calorimeter for experiments , which has such characteristics :
- curing at any temperature, if necessary up to 70 °C
- testing duration of any duration, up to 28 days or even more
- Heat of hydration test according to ASTM C1702
- high-precision research with the need for the best signal-to-noise ratio (minimum crosstalk)
