Clay is a naturally occurring soil material that is composed of fine-grained minerals. Clay is different from any other soil type. The soil has tremendously grown in popularity due to its fantastic construction characteristics. This is due to its plasticity through a varying amount of water content and is hardened when fired or dried. This article goes through 3 amazing facts about clay construction.
1. Clay Construction Dates Back to 7500BC
The used of unbaked clay bricks for construction houses dates back to about 7500BC. For thousands of years, primitive people used any elements that could protect them in constructing shelters, including clay. The Sumerians were the most advanced group of people throughout the ancient world and located in Mesopotamia, and they were the pioneers of the current civilized world. Living between river Tigris and Euphrates, they made their houses from the river clay. However, the walls of the homes would melt during floods. In the 2600BC, they solved the problem by firing the clay.
2. Fired Clay Bricks Can Last for Million Years
Fired clay bricks can also be referred to as a synthetic rock. This is because it has similar properties to that of basement rock. The reason behind this is that clay bricks are manufactured from clay. When fired at about a thousand degrees centigrade, the brick becomes a basement rock. To change it back, it will take very many years. This makes clay to be among the best and frequently used construction materials. Cray bricks can withstand extreme temperature changes hence considered one of the most long-lasting material.
3. The Clay Minerals Determine Its Color
According to research studies, the minerals used in creating a cray brick determines its color. Clay minerals are formed over a couple of years by gradual chemicals rock weathering due to the low concentrated carbonic acid. Red bricks result because of the iron components contained in them. Extreme temperature produces darker colored blocks – read article on how to make red bricks.
