Basalt is an extrusive igneous rockt is the bedrock of the ocean floor and also occurs on land in extensive lava flows.
Basalt rock as an alternative raw material in portland when the basalt rock is applied in cement industry, this composition of basalt clinker mixture could be adjusted by adding a little amount of sand to compensate the lack of silicon oxide, as iron oxide always added to the clay clinker mixture to compensate the lack of iron in clay.

Therefore, these numbers translate directly to gcm 3, or tonnes per cubic meter tm 3rock densities are useful to engineers, of courseheyre also essential for geophysicists who must model the rocks of the earths crust for calculations of local gravityineral densities.
