Air loss can also be significant when compared to concretes without high range water reducers held at constant water-cement ratios. The effectiveness of water reducers on concrete is a function of their chemical composition, concrete temperature, cement composition and fineness, cement content, and the presence of other admixtures.

The exact composition of slag varies over a range. In general, factors that determine the suitability of slag for usage in composite cement mainly include the fineness of grinding, glass content and the chemical composition. Fineness Like most of other cement materials, the reactivity of slag is influenced by its surface area.
The users of cemented joint replacement need to know the chemical and physical properties of bone cement, which change by even slight variations in the chemical composition. The final bone cement is produced by nurses and surgeons in the operating theatre. These users have enormous influence on the quality of the final cement.
Acid-resistant cement is manufactured by mixing of acid-resistant aggregates like quartz and sodium fluosilicate Na 2 with ordinary cement. USES ARC cement is widely used in the chemical industry. 13. Coloured Cement. Coloured cement is manufactured by adding 5 to 15 of suitable pigment while grinding the cement. Example
Chemical Composition Portland cement clinker consists predominantly of compounds formed from calcium, silica, alumina and iron. Calcium sulfate is present in cement due to the gypsum addition to control setting time and up to 5 of minor additional constituents may be added for CEMI Portland cement in accordance with
Portland Pozzolana cement is integrated cement which is formed by synthesising OPC cement with pozzolanic materials in a certain proportion. It is commonly known as PPC cement. In this article we discuss about the properties, manufacture, characteristics, advantages and disadvantages of Portland Pozzolana cement. ContentsWhat is pozzolana or pozzolanic materialTypes of pozzolana materials
Jun 01, 2017018332The chemical composition of glass powder is compared with other pozzolanic materials in the discussion. As the results of fineness, specific gravity and chemical composition test of color and clear glass powder were found similar, further experimental work with mortar and concrete was conducted with clear glass power.

The chief chemical components of ordinary Portland cement are Calcium, Silica, Alumina, Iron. Calcium is usually derived from limestone, marl or chalk while silica, alumina and iron come from the sands, clays amp iron ores. Other raw materials may include shale, shells and industrial byproducts. The chief compound which usually form in process of mixing
The method of grinding cement may also influence the hydration kinetics. Cements ground in high pressure roller mills set faster than in ball mills, because of higher reactivity of C 3 A and C 3 S phases, and a lowered rate of decomposition of CaSO 4.
