What are the raw materials used in the manufacture of portland cement? A. The two principal materials from which portland cement is made are a material of high lime content, such as limestone, chalk, shells, or marl, and a material of high silica and alumina content such as clay, shale, or blast-furnace slag. A small amount of iron is also needed.
The phosphorus content of the commonly used natural cement raw materials is very low; in Ger many, the P205-content of the clinker is within the li;mits of about 05 and 0.25 % [139]. In cases where raw materials with a higher phosphorus content are used (e. g. limestone with a high P205-content, or industrial wastes from phosphorus production ...
Raw Materials The concrete commonly used to make concrete blocks is a mixture of powdered portland cement, water, sand, and gravel. This produces a light gray block with a fine surface texture and a high compressive strength. A typical concrete block weighs 38-43 lb (17.2-19.5 kg). In general, the concrete mixture used for blocks has a higher ...

AASHTO T260 is a standard test method used to determine the chloride ion content in concrete, aggregates, Portland cement, mortar, and other concrete raw materials. Chloride ions, when present in excessive amounts, can cause corrosion of steel reinforcement in concrete, leading to structural deterioration and reduced service life.

These materials are typically obtained from quarries or mines, where they are carefully selected and excavated. The quality and composition of the raw materials play a crucial role in the final properties of the cement [35, 36]. Once extracted, the raw materials undergo a series of preparation processes.
The compilation and synthesis of major cement and concrete production LCAs conducted since early 2000s are tabulated in Supplementary Materials, Table S1.A recent study by Van den Heede and Belie [13] also reviewed the literature about the LCA of concrete, compiled ranges of energy and emissions data for both traditional and "green" concrete …
