Concrete and cement are frequently used interchangeably to refer to the same item, such as concrete driveways. Concrete and cement, on the other hand, are not the same thing. They’re made of wholly distinct materials and have quite different functions.
What Exactly Is Cement?
Cement is a substance that is used to make concrete. To make cement Malaysia, clay and limestone are used as binders. Both of these ingredients are heated to extremely high temperatures before being pulverised into a fine powder. To activate the chemical binding action and hydration reactions present in cement, it must be heated.
You wouldn’t obtain the same results if you just ground up hardened clay and limestone. While you’d acquire a fine powder, the results would be inferior than those obtained by heating these materials to extremely high temperatures.
Clay and limestone must be heated to at least 2,642 degrees Fahrenheit to activate the chemical characteristics of cement.
What Exactly Is Concrete?
Concrete is a mixture of several elements that is made by combining aggregates with water. Sand, gravel, pulverised brick powder, stones, pebbles, and cement are all examples of aggregates. The aggregates used will determine the strength of the concrete and the applications for which it can be utilised.
For example, if you mixed sand, gravel, and powdered brick powder together, you’d obtain a cement mixture that could be used to build paving tiles, but it wouldn’t be as strong as concrete with cement. This is because ground brick powder lacks the chemical binding and hydration processes that cement does.
Other Than Concrete, What Is Cement Used For?
You might be shocked to hear that cement isn’t just for making concrete when mixed with particles. Various materials can be made by mixing cement with other particles.
Plaster powder, commonly known as cement plaster, is formed of a combination of cement and sand. The plaster paste is then made by adding water and can be utilised for a variety of reasons.
Another example is mortar, which is typically used to keep bricks together and secure them in place. Lime, cement, and sand are combined to make mortar powder. When you mix it with water, you obtain wet mortar, which you can use to join bricks.
How Did Cement Get Its Start?
Joseph Aspdin, a bricklayer from the United Kingdom, invented cement. He had been experimenting with various materials in order to create an “artificial” stone that might rival the strength of Portland stone. He then boiled clay and limestone together and crushed it into a powder probably in the 1820s.
He blended this powder with various materials, effectively inventing modern mortar and plaster, which we still use today. He also discovered that by using the appropriate proportions of water, sand, gravel, and cement, he could make concrete that would strengthen as it hardened and aged.
Portland cement is the name given to the cement he created. Some people believe this is a company or brand name. It is, however, only one sort of cement, which also happens to be one of the most extensively utilised nowadays.
