Jun 01, 2017· The cement manufacturing process accounts for about 5% CO 2 (carbon dioxide) released into the atmosphere. However, during its life cycle, concrete may capture CO 2 through carbonation, in order to, partially, offset the impact of its production. Thus, this paper aims at studying the CO 2 uptake potential of the Itaipu Dam due to concrete carbonation of such material.

Raw materials - Cement

This is a fluxing agent which reduces the melting temperature of the raw materials in the kiln (from 3,000 o F to 2,600 o F). It hydrates rapidly, but does not contribute much to strength of the cement paste. By mixing these compounds appropriately, manufacturers can produce different types of cement to suit several construction environments.
