To better understand how material selection and building operations influence these and other environmental factors, green building design professionals are turning to life cycle assessment (LCA) to quantify environmental impacts during each phase of a building''s ...
The cement industry recognizes its responsibility to manage the environmental impact, associated with the manufacturing of its product. Mainly, there are two types of cement production process; such as wet process and dry process. The preparation of cement includes mining, crushing, and grinding of raw materials, calcining the materials in 1408
Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and nonspecialty was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and usually originates from is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker ...

Mar 08, 2016· The use of GGBFS as a partial Portland cement replacement takes advantage of the energy invested in the slag making process and its corresponding benefits with respect to the enhanced cementitious properties of the slag. Grinding slag for cement replacement requires only about 25 percent of the energy needed to manufacture Portland cement.
Cement. Environmental impact of cement production is calculated based on the data provided by Ecoinvent (2012). Detailed information on the production process and on all inputs can be taken from Künniger et al. (2001). The functional unit is the production of 1 kg of Portland cement strength class (CEM I R).

The impact categories considered are those resulting from the manufacture of cement and include greenhouse effects, acidification, eutrophication and summer and winter smog, amongst ...
Jan 01, 2013· The grinding process impacts the cement manufacture in at least two ways. First, an increase of the fineness and homogeneity of the raw mix accelerates the clinkering reactions, leading to less variability of the clinker due to the enhanced stability of the kiln and better energy efficiency in producing a clinker of better consistency ...
Cement Conservation to Reduce Environmental Impact of Concrete The conservation of cement is the first and most important step in decreasing both energy utilization and greenhouse gas emission. Resource productivity consideration stipulates the deduction of the utilization of Portland cement while meeting the future demands for more concrete.

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.
