Frank, In order to a high enough granite percentage it is necessary to have a mixture of aggregate sizes. The voids between the large pieces get filled with the medium size pieces and the voids in the medium size pieces get filled with the small pieces. Other voids are hopefully filled with epoxy.

Very interesting. it wasn't until I came to live in NH for 3 years that I began to appreciate the effects that water/ice and very cold weather could have on everyday things. It was an education but I am glad to be back in warmer climes, with the cold being a distant memory.
