Manufacturing of cement involves various raw materials and processes. Each process is explained chemical reactions for manufacture of Portland Cement. Cement is a greenish grey colored powder, made of calcined mixtures of clay and limestone. When mixed with water becomes a hard and strong building material.
For cement packing, cloth, jute, and high-density Polythene (HDPE) bags are commonly used. For convenience, the cement comes to the customer in bags containing measured quantity. The standard bag of cement as distributed in India is commonly 50 kg or 112 .5 lbs. 2. Wet Process of Manufacturing of Cement.
Cement production is one of the largest industries in the world. Annual world production in 2013 was approximately 4 GT (of which, about half was in China). It is produced in kilns at around 1400o C (2500 o F), and approximately 750 kg (1650 lb) of CO 2 are released for each tonne (2205 lb.) that is made.

Production of cement begins in a rotary kiln in which limestone and clay are heated to approximately 1,450 degrees Celsius. Under these extreme conditions, a semi-finished product called clinker is then formed. Different high-grade additives then produce the different kinds of cement. Lafarge Cement Zimbabwe has three flagship products.

CO 2 is a greenhouse gas (GHG). The cement production capacity in India is estimated to rise from the current (2014) 366x10 6 t/a to 550x10 6 t/a in 2020. Along with the rise in production, there ...
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
In this study the process flow diagram for the cement production was simulated using Aspen HYSYS 8.8 software to achieve high energy optimization and optimum cement flow rate by varying the flow rate of calcium oxide and silica in the clinker feed. Central composite Design (C.C.D) of Response Surface Methodology was used to design the ten experiments for the simulation using Design Expert 10.0.3.

Classification Code (SCC) for portland cement plants with wet process kilns is 3-05-006, and the six-digit SCC for plants with dry process kilns is 3-05-007. Portland cement accounts for 95 percent of the hydraulic cement production in the United States. The balance of domestic cement production is primarily masonry cement. Both of these
Cement production also is a key source of CO2 emissions, due in part to the significant reliance on coal and petroleum coke to fuel the kilns for clinker production. Globally, CO2 emissions from cement production were estimated at 829 MMTCO2 in 2000 7, approximately 3.4% of global CO 2 emissions from fossil fuel combustion and cement production.
cement - cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
