Protection against Wave-based Erosion

2020-9-8  Sandstone and limestone can be used for armor stone. Allowances for the lighter mass density of sandstone (specific gravity of 2.2 to 2.5 for sandstone versus 2.6 for limestone) must be included in the design calculations. Sandstone is more resistant to cracking than limestone but it is also a softer material and more easily eroded.
