Properties of Cement- Physical & Chemical - Civil Engineering

Ferrite is a fluxing agent. It reduces the melting temperature of the raw materials in the kiln from 3,000°F to 2,600°F. Though it hydrates rapidly, it does not contribute much to the strength of the cement. Magnesia (MgO) The manufacturing process of Portland cement uses magnesia as a raw material in dry process plants.

Portland cement - Wikipedia

Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout.It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and is usually made from limestone.It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker

HAPTER 2 ONCRETE CONSTRUCTION MATERIALS

Portland cement is hydraulic cement produced by pulverizing clinker, which consists of calcium silies formed from limestone (CaCO. 3), silica (SiO. 2), alumina (Al. 2. O. 3), and ferrous oxide (Fe. 2. O. 3). ASTM C150 is the standard specifiion for Portland cement. Portland cement also may include water, 5% limestone, and processing

Alkali–silica reaction - Wikipedia

The main phases are the calcium silie hydrates (C-S-H) (the "glue" in cement paste), calcium sulfo-aluminate phases (AFm and AFt, ettringite) and hydrogarnet. C-S-H phases are less soluble (~ 10 −5 M) than portlandite (CH) (~ 2.2 10 −2 M at 25 °C) and therefore are expected to play a negligible role for the calcium ions release.

Materials - Fireproofing for Petrochemical facilities

The industry considers gypsum-based plasters to be cementitious, even though these contain no Portland, or calcium aluminate cements. Cementitious plasters that contain Portland cement have been traditionally lightened by the use of inorganic lightweight aggregates, such as vermiculite and perlite.

DETERMINATION OF CALCIUM AND MAGNESIUM IN …

The quality of cement as per standard specifiion is very important Calcium Aluminate The above syols are used in cement manufacturing industries. The main constituent of the cement and clinker is calcium oxide (CaO) which is the major factor for cement quality. It is determined by several analytical techniques.
