9. P Cal Set can help you predict initial and final setting times within close approximation by applying the Fractions Method and generate Thermal Indicators of Set TIS This method is based on the assumption that for a given mix design there is a correlation between the heat evolution and setting times Initial set is reached when the temperature level in a sample placed in the P Cal reaches a certain fraction of the peak Each mix has its very own fraction values corresponding to initial and final set Once the fraction values are determined for a given mix design they can be used to predict setting times when the same mix is used again in the future How to use the F Cal Set module To be able to predict setting times for a given mix design you will first have to create a model which establishes the relationship between the temperature curve and initial and final set as measured by a standard method for example ASTM C403 First build a model To build a new Model for a given mixture proceed as follows Go to F P Cal Set and select the Modeling tab Click on New Model a 2 Click on Add Modeling Log b A new window will pop up letting you browse to the file containing the calorimetry curve for the mix for which you would like to build a model You can load up to 8 curves for the same mix 3 Select one or several curves for this mix and click on Accept The selected curve s will appear on the screen as shown below
