What is the density of sand, stone, cement and water

The main component of sand is silica, and the density of silica is 2.65g/cm3. The density of sand is smaller than this density because of its voids. The density of various stones is different, and the specific gravity of some stones is as follows: Granite: 2.63 ~ 3.3, syenite: 2.3.3, diorite: 2.3.3, porphyry: 2.8, andesite: 2.3.3, diabase
