ABSTRACT
The packing of the solids is of essential importance for the properties of fresh and hardened concrete. By the help of the fundamental understanding of the working mechanism of particle packing it is possible to control the behavior and the characteristics of products based on granular materials. Therefore, a lot of research into the field of particle packing was carried out in the last century. Based on the work of Fuller & Thomsen (1907), Andreasen & Andersen (1930) studied the packing of continuously graded particles and led them to the semi-empirical equation for the cumulative volume fraction F(D):
where D = particle size; Dmax = maximum particle size; and q = distribution modulus.
