The major cements: composition and properties Portland cement stone composition. Portland cement is made up of four main compounds: tricalcium silicate (3CaO · SiO 2), dicalcium silicate (2CaO · SiO 2), tricalcium aluminate (3CaO · Al 2 O 3), and a tetra-calcium aluminoferrite (4CaO · Al 2 O 3 Fe 2 O 3).

Analysis of stone Composition of Portland Cement in

The performance of Portland cement in concrete or mortar formation is very well influenced by stone compositions among other factors. Many engineers usually have little information on the stone compositions of cement in making decisions for the choice of commercially available Portland cement in Ghana. This work analyzed five different brands of Portland cement

Microsilica is appropriately added to cement composition. Impermeable tight set cement structure is formed due to good size grading between microsilica and cement particles, thus preventing corrosive media from further erosion. b. A latex cement system is used. Set cement pores are filled with polymer films or gel particles so that set cement

It is supposed to be the best cementing material and is well-burnt cement. It is about 25-50% (normally about 40 percent) of cement. It renders the clinker easier to grind, increases resistance to freezing and thawing, hydrates rapidly generating high heat and develops an early hardness and strength.
