Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive magnetic properties. It constitutes 5 percent by weight of the Earth's crust, and it is the fourth most abundant element after oxygen, silicon, and aluminum.It melts at a temperature of 1,538° C (2,800° F). Iron is allotropic—that is, it exists in different forms.
High Alumina Cement (HAC), sometimes known as calcium aluminate cement (CAC) or aluminous cement, is composed of calcium aluminates, unlike Portland cement which is composed of calcium silicates. It is manufactured from limestone or chalk and bauxite.
