cement
Cement is a man-made material produced by heating and grinding together a mixture of limestone and clay. It is not generally considered a natural material due to the extensive human processing involved in its production.
Limestone would be potentially harder until the clay is fired. The problem we have here is that "clay" is an ambiguous term. There is no homogenous or standard formula for clay. However, clays can generally be formed and baked to become set and hard. This is called firing. Fired clay tends to be quite hard, and depending on the formula, might be harder than limestone.
It is man made. The basic ingredients are limestone and clay which are roasted in a kiln.
Stair Hole in Dorset, England, is made predominantly of limestone, which has been eroded over time due to the action of the sea. Limestone is a sedimentary rock formed from the accumulation of marine organisms.
Limestone is mainly made up of the mineral calcite, which is a form of calcium carbonate. It may also contain varying amounts of other minerals such as clay, dolomite, and silica.

The egyption Pyramid is maily made out of limestone, granite, and clay.
It is made out of limestone blocks and desert clay. anyways hi.
Limestone is made up of calcium oxide which is the key ingredient to make cement. The limestone is mixed in with a particular clay to get the cement mixture.

clay is made up of limestone that's a mineral clay is made up of
mostly rocks and stone and they used bird droppings and egg whites to make concrete
Most cements are made from a mixture of pulverized limestone and clay, so technically it is made out of rock.
Sediment is made from clay, gravel, some organic matter, weathered limestone and basalt.
It is man made. The basic ingredients are limestone and clay which are roasted in a kiln.
