About Packing
This program can be used to calculate the optimum combination of two or three aggregate, cement and/or filler fractions with respect to packing density. The program calculates the maximum packing density. In general, increasing the packing density improves several properties of concrete and reduces the paste volume and thus the required amount of cement.
The calculations are based on the modified Toufar model.
The app is still under construction. Graphs and a fourth fraction will be added soon.
