Limestone From Cairo Minerals Silica Sand in Egypt
Limestone is a producer of quicklime and slaked lime. It is widely used for the production of Portland cement and mortar. Limestone is burnt to create lime, along with other raw materials ash and sand. Together, they form a product called clinker. Clinker is then mixed with gypsum and crushed to form a powdery mixture.
Shale Rock: Geology, Composition, Uses
Shale is the most common sedimentary rock, accounting for about 70 percent of the rock in the Earth's crust. Shale is a fine-grained rock made from compacted mud and clay. The defining characteristic of shale is its ability to break into layers or fissility. Black and gray shale are common, but the rock can occur in any color.
