New Amendment to ASTM C150 ... New Possibilities

 

The upcoming amendment of ASTM C150 offers the possibility to use isothermal calorimetry to determine the heat of hydration as per ASTM C1702.

 

Previously, ASTM C186, or "heat of solution method", was the reference test method in C150. Serious drawbacks of this method include the use of hazardous chemicals, the lack of availability of equipment and the variability of test results. The new isothermal calorimetry method does not present any of these issues: it is a completely safe procedure, with highly repeatable results and isothermal calorimeters are readily available in the market.

 

Calmetrix offers three models that are compliant with ASTM C1702. And all of them offer other useful applications beyond ASTM C1702 heat of hydration testing. See below to discover what calorimeters have to offer.

Sulfate Optimization

 

Calorimetry curves can be used to troubleshoot sulfate imbalance and to find an optimum numerical value of sulfate content, as shown in the Application Notes and Video to the right.

Compressive Strength Estimation 

 

Isothermal Calorimetry is a powerful and easy-to-use method to estimate compressive strength, instead of casting cylinders or cubes for physical testing, and without the need for a temperature controlled curing chamber. See a presentation by cement manufacturer Aalborg Cement (Cementir) on how early strength development correlates to heat of hydration.
