Cement

Cement is essentially a finely powdered mixture of calcium silicate and aluminates along with small quantities of gypsum which sets into a hard stone like mass when treated with water. Average composition of Portland cement Cement is obtained by combining a material rich in lime, CaO with other materials such as clay, which contains silica, …

Characteristics Of Compounds Of Alkaline Earth Metals

Due to higher enthalpy of formation in the solid state and due to higher hydration enthalpy in the aqueous solution, alkaline earth metals uniformally form bipositive ions. Due to increased nuclear charge and smaller size, alkaline earth metals form compounds which are less ionic than the corresponding compounds of the alkali metals. Oxides and Hydroxides …

Reactivity And Electrode Potential Of Alkaline Earth Metals

All the alkaline earth metals are highly reactive elements since they have a strong tendency to lose the two valence s-electrons to form the corresponding dipositive ions having inert gas configuration. Reactivity arises due to their low ionization enthalpies and high negative values of their standard electrode potential. The chemical reactivity of alkaline earth metals …
