· The direct CO2 intensity of cement production increased % per year during 201418. To get on track with the SDS, a % annual decline is necessary to 2030. Sharper focus is needed in two key areas: reducing the clinkertocement ratio (including through greater uptake of blended cements) and deploying innovative technologies (including CCUS).

plays a key role in delivering sustainable productivity to the global mining and cement industries to support this. 1. Minerals and electronics. of minerals. 2. Cement for construction. By 2030, 60% of the global population will live in cities. Urbanisation like this requires cement for construction. 3.
They are called cement rocks because they can be used as a single raw material for the cement manufacturing process. 3. Gypsum: It is generally added in very small amounts (about 2% by weight) to the burnt cement (called Clinker) after it is taken out from the kiln and before it is sent for grinding. Gypsum is a sedimentary rock having a composition of calcium sulfate (Ca SO 4. 2 H 2 O). It is ...

· Civil Concrete Technology Lectures Notes Concrete Definition In its simplest form, concrete is a mixture of paste and aggregates (rocks). The paste, composed essentially of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a series of chemical reactions called hydration, the paste hardens and gains strength to form the rocklike .
