Cement Types

Type II cements are limited in C150/M 85 to a maximum of 8 percent by mass of tricalcium aluminate (a cement phase, often abbreviated C 3 A), which impacts a cement's sulfate resistance. Certain oxides are also themselves limited by specifications: For example, the magnesia (MgO) content which is limited to 6 percent maximum by weight for portland cementsGet price

Cement composition and classification

2015/6/25Of these groups, the best known to the oil industry are ASTM, which deals with cements for construction and building use, and API, which writes specifications for cements used only in wells. The ASTM Spec. C150 [1] provides for eight types of Portland cement: Types I, IA, II, IIA, III, IIIA, IV, and V, where the "A" denotes an air-entraining cement.Get price

High Temp Furnace Cement

High temp furnace cement is refractory material which can be used as binding agent in the making of monolithic refractory. It has high refractory temperature which is over 1580 and high strength. Due to its sound performances, it can be applied to glue all kinds of refractory aggregate and also can be used on the linings of many industrial furnaces and kilns.Get price

Are You Mining Minerals for Cement, or for Concrete?

Some typical materials used for iron in cement manufacturing are iron ores, blast furnace flue dusts, pyrite clinker, mill scale, and fly ash." Cement manufacturers must process the selected and prepared mineral raw materials to produce the synthetic mineral mixture (clinker) that can be ground to a powder having the specific chemical composition and physical properties of cement.Get price

Blended Cement

Composite cements with fly ash additive can be used to produce concretes for special application. They are suitable for producing alkaline and sulfate corrosion-resistant concrete. Use of fly ash-slag mix allows optimization of the main characteristics of cement clinker and reduction of CO 2 emissions due to a greater cement/clinker ratio.Get price
