    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. Also, I-Cal 4000 HPC is fully compliant with ASTM C1679, ASTM C1702, ASTM C563 and EN 196-11.

    Features

    - Type of instrument: Isothermal Calorimeter
    - Number of test channels: 4
    - Suitable for cement paste, mortar or concrete


    Examples of use:

    - Cement and Concrete Technology
    - Cement plant quality control
    - Admixture development
    - Geopolymers
    - Sustainable cements


    The ambient temperature around the samples is computer-controlled by Calmetrix's software interface, with precision sensors measuring the heat flow generated by the cement hydration reaction. But the I-Cal HPC line of calorimeters distinguishes itself by its clever design to minimize sensitivity to outside conditions. This means more consistent results, but also a robust performance even in a non-air conditioned environment, a definitive benefit in terms of reproducibility, and cost savings for field laboratories or rooms that are not tightly air-conditioned.

     
    Applications:

    I-Cal 2000 HPC is well adapted for applications in R&D and Investigative work on cement and concrete properties, as well as daily QC needs in cement and concrete production. Typical uses are:

    • heat of hydration measurement as per ASTM C1702
    • detection of potential material incompatibility (between cement and admixtures, etc.)
    • admixture formulation
    • shotcrete accelerator studies
    • sulfate optimization
    • sensitivity tests on variations in admixture or other material content
    • estimation of compressive strength using heat of hydration curves
    • determination of activation energy for thermal crack prediction
    • sensitivity tests on temperature variations
    • mix design optimization and statistical performance analysis​
    • test temperatures of more than 50 °C (up to 70 °C), e.g. for studies of delayed ettringite formation
    • characterization of supplementary cementitious materials


    ​I-Cal 4000 HPC is the right isothermal calorimeter for experiments that have the following characteristics:

    - curing at any temperaure, and up to 70 °C when needed
    - test durations of any length, up to 28 days or even longer
    - Heat of hydration testing as per ASTM C1702


    Quick Specifications

    Operating Voltage: 110 - 240 VAC - 50/60Hz - 50W
    Number of Test Channels: 4
    Operating Temperature Range: 5 to 70 °C (41 to 158°F)
    Temperature Stability: < +/- 0.02°C in laboratory conditions
    Software Compatibility: CalCommander on Windows XP or later
    Max. Recommended Test Duration: 28 days
    Sample Size: up to 125ml / ~340g mortar (12oz.)
    Baseline (over 72h*): < 0.05uW/g/h (Drift); < +/- 2uW/g (Random Noise);
    Dimensions (LxWxH) - 21.5in x 16.5in x 22in (55cm x 42cm x 56cm)
    Weight - 104lb, 47kg

    * Baseline is measured at 23 °C for 3 days on a 50 g sample. A straight line is fitted to the power (J/g/s) versus time (h) data using a linear regression procedure. The long term drift is the slope and the baseline noise level is the standard deviation around this regression line.
