Cylinders can be used to test paste, mortar and real concrete and can be capped to be later used for compressive strength testing.
F-Cal uses Calmetrix's proprietary CalCommander software for data retrieval and analysis. CalCommander enables users to select one of the F-Cal's cells as a temperature reference cell. The reference cell generally contains an inert material, such as a fine aggregate. This is useful when there is a need to normalize temperature curves obtained under different ambient conditions (e.g. summer vs. winter)
F-Cal is recommended for testing in field conditions for up to 36 hours (*). Heat curves obtained can be interpreted almost instantaneously by the user, or stored and sent in a report to an off-site QC Manager.
F-Cal does not require a dedicated computer or a power source. The only times a computer has to be connected is to start up the equipment and to retrieve data. At any other time, data is stored in an internal memory with up to 7 days capacity. The unit's internal battery will last up to 3 years of uninterrupted operation.
F-Cal is used in the FIeld by Concrete Manufacturers and Suppliers of cement, supplementary cementitious materials or chemical admixtures. Main applications are:
• on-site troubleshooting for material incompatibility (e.g. admixtures that do not work well for certain cement sources)
• quick estimation of setting times
• rapid screening of materials, e.g. different sources of cement, different brands of admixtures
• robustness test (how performance holds up to variations in material dosages)
• mix design optimization
(*) For improved signal-to-noise ratio and longer test periods up to 28 days or longer, see the Calmetrix P-Cal 1000 high performance calorimeter.
F-Cal is a handy, portable calorimeter that emulates the curing conditions of concrete flatwork. It is ideal for quick testing of concrete in field conditions.
F-Cal units are portable, yet rugged enough to be carried in the back of a pick-up truck, or left on site in a Concrete plant for testing in real conditions.
F-Cal comes in two versions:
