As a key input into concrete, the most widely used construction material in the world, cement is a major contributor to climate change. the chemical and thermal combustion processes involved in the production of cement are a large source of carbon dioxide co 2 emissions.each year, more than 4 billion tonnes of cement are produced, accounting for.
Cement is a fine powder, obtained from the calcination at 1,450 c of a mix of limestone, clay, and iron ore. the product of the calcination process is clinkerthe main ingredient of cementthat is finely ground with gypsum and other chemical additives to produce cement.
Cement is made by heating limestone calcium carbonate with other materials such as cla y to. 1450 c in a kiln, in a process known as calcinations, whereby a molecule of carbon dioxide is.
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.

Clinker can be easily handled by ordinary mineral handling equipment and can be stored for several months without compromising on the quality. clinker is the primary product in the cement manufacturing process where limestone, clay and sand are grinded and heated, before the gypsum is added to produce the final product of cement..
Concrete has also been identified as the largest contributor to the environmental impact of conventional buildings hoxha et al., 2017. cement is the key component needed for the production of concrete and its production is responsible for around 5 of all anthropogenic carbon dioxide co 2 emissions worldwide hasanbeigi et al., 2012.
Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden. cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients.
Concrete is used for a large variety of constructional purposes. mixtures of soil and portland cement are used as a base for roads. portland cement also is used in the manufacture of bricks, tiles, shingles, pipes, beams, railroad ties, and various extruded products. the products are prefabricated in factories and supplied ready for installation.
Concrete production is a highly intensive energyconsuming process and presently facing a number of challenges in reducing the carbon footprint and making it more economic. sustainable technologies in maintaining concrete structures are proving to be a great challenge. microbially induced carbonate precipitation micp has developed as a novel and sustainable technique.
