This type of cement was invented in the early 19th century by joseph aspdin. it is named portland cement because its property is similar to the stone quarried on the ise of portland, england. the making process of portland cement in the modern industry can be divided into the wet process, dry process, and semidry process.
To determine the effects of using a byproduct on the manufacturing process, cement performance and facility emissions. portland cement is the basic ingredient of concrete. concrete, one of the most widely used construction materials in the world, is formed when portland cement creates a paste with water that binds with sand and rock to harden.
