It's often known as “hydraulic cement”, because it is able to placing and hardening when blended with water, since the chemical reaction amongst the two creates a material with fantastic binding Attributes.
Portland cement was invented in 1824, but during heritage there are actually several, many mixtures which have resulted in an array of cement.
They're some of the characteristics that have made it Among the most utilised materials in all types of developing operates.
