Cement is an essential component of the building and remodeling process, but it’s something that many of us probably have not given much thought to. We know that Broadway makes Ready Mix Concrete, but we wanted to know more. A recent article helped us break it down.
The Origins of Cement
Cement was first manufactured in the early 19th century by a bricklayer named Joseph Aspdin. He used his kitchen stove to burn powdered limestone and clay, making the first known version of what would become today’s modern cement. (We wonder how his wife felt about her kitchen being used this way?!)
What is Cement Made Of?
Today, cement is manufactured using a variety of raw materials, including limestone, chalk or shells combined with clay, shale, silica sand, blast furnace slag, slate and iron ore. When the materials are heated at a high temperature (upwards of 2,500 degrees Fahrenheit!) they form a rock-like matter, which is then ground into a fine powder.
Cement vs. Concrete
The two are closely intertwined: cement is the primary ingredient of concrete. To make concrete, the powder is mixed with water to make a paste, which binds with rock and sand to harden.
How is Cement Manufactured?
The most common way that cement is manufactured is through a dry method. First, the raw materials are quarried and crushed until they are three inches or smaller. Then, the crushed rock is mixed with other ingredients, which are ground and mixed, before being heated in a kiln. Finally, the mix is cooled and ground to its final powder form.
