## HPC-09 v6 Example: No Bed Heat

In this example no Bed Heat is used. HPC-09 v6 Initial Prediction (Blue Graph) calculates that a Pouring Temperature of 25 deg C is required to reach the Target Strength in the Target Curing Time.

Corrected Prediction (Red Graph) shows that the actual Pouring Temperature is 26 deg C, and thus the Curing Time will be shorter than the Target Curing Time.

Calculations that does not involve Bed Heating, is usually even more accurate than calculations that involves Bed Heating. The reason being that Bed Heat often varies somewhat in unpredictable ways.

The Green Graph is the actual measured Temperature, and we can see how it in this case corresponds close to 100% with the Red Graph: This accurate Prediction is what makes HPC-09 v6 able to Calculate a Minimum Pouring Temperature and thus Saving Energy.

Red Graph: HPC-09 v6 Corrected Predicted Temperature: Green Graph: Actual Measured Temperature.

We also get a very good correspondence between the Corrected Predicted Strength (Red Graph) and the Real Time Calculated Strength (Green Graph).

Red Graph: HPC-09 v6 Corrected Predicted Strength: Green Graph: Actual Calculated (Real-Time) Strength.

Strength Calculation

Correspondence between  Corrected Predicted Strength and the Real Time Calculated Strength is of no use if the Cube Strength and the Real Time Calculated Strength does not match! However, even in this department HPC-09 v6 has proved to be very reliable: Typical Standard Deviation between Real Time Calculated Strength and the Cube Strength is typically as low as 1.5 MPa. In the example below it is even as low as 1.36 MPa for 46 samples!
