The primary cement manufacturing process involves the mining of raw materials, mainly limestone and clay, which are used in cement manufacturing. In most of the cases, the limestone and clay are excavated from open cast mines by drilling and blasting and other appropriate processes in mines. Subsequently, the limestone and clay There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as “ clinker,” together with some 5 percent of gypsum (to control the time of set of the cement). The three processes of Cement Extraction, Processing, Manufacturing Britannica

Calcium-based binders, such as ordinary Portland cement (OPC) and lime (CaO), are the most common artificial cementitious materials used worldwide for concrete and soil improvement. However, using cement and lime has become one of the main concerns for engineers because they negatively affect the environment and economy, A form of cement was known and used for construction 2000 years ago by the Romans. Mixed with water and then combined with sand and gravel, it hardens to concrete or mortar. Industrial production of cement in the Austro-Hungarian Em pire started in the middle of the 19th century and reached a volume of 600 kt by 1900, rising to 1 430 Cement Production in Austria Springer

Several methods are used to cure concrete during the manufacturing process. Curing aims to ensure that the concrete reaches its maximum strength and durability potential and prevents it from getting moist. Following are some of the prevalent methods of curing. 1. Water Curing: This is the most common method used to cure concrete.The attention to environmental impacts of cement production has grown fast in recent decades. The cement industry is a significant greenhouse gases emitter mainly due to the calcinations of raw materials and the combustions of fuels.

On the final stage, the cement is packed and ready for commercial use. Production of concrete is done in a machine called a concrete mixer. The process mixes 15% cement, 10% water, 25% grains of sand and 50% gravel (small stones). All those raw materials are poured into the concrete mixer which continuously rotates to form concrete.The cement production process is a multiplex process that uses a considerable amount of raw materials (limestone), fuels (thermal energy) and electricity, as well as auxiliaries such as water and air [1,2,3,4].
