When Were Concrete Block Machine First Made
Posted by admin in Machine, Uncategorized on August 12, 2010
People have used concrete since ancient times, but the concrete block machine was not invented until the 1830s. Widespread manufacture of concrete blocks began in the early 1900s, and their popularity grew rapidly. Since then, they have been used in an enormous number of projects including basement walls, commercial buildings and more.
History
Ancient Romans or Greeks are traditionally considered the inventors of concrete from around the first century B.C., constructing it from lime, volcanic sand and ash, small stones, and water. Romans used concrete extensively in structures such as the Pantheon, the interior of the Coliseum and aqueducts.
Time Frame
The first precast concrete blocks were cast in wooden frames, dried like bricks into a solid form, and then laid in mortar like bricks, as well. Many individual contractors were creating these precast blocks by the mid-1800s. The first house in the United States built entirely of these blocks was constructed in 1837 on Staten Island, New York.
Types
In 1824, an English inventor named Joseph Aspidin invented a style of cement, a modified form of which is still the dominant type in construction today. It was made of powdered limestone and clay mixed with water. Aspidin named Portland cement after a type of building stone that was quarried on the Isle of Portland in Dorset, England.

The Washing Machines of Tomorrow
Have you ever thought of the possibility of having internet powered washing machines? You may not have realized it but the truth is that such machines may soon turn this industry to what the mobile market is today: a hotbed of competition. What about the possibility of having washing machines that are powered by solar, wind energy or even geothermal energy? Such machines could soon help the consumers in cutting their monthly energy bills on top of other benefits that would come along. It is envisioned that even more exciting and exotic things are on the way within a decade or two to come. Can you imagine a situation where light bulbs communicates with or talks to switches, and everything talks to the internet? How about a scenario where windows and paint can change color to either harvest sunlight or reject it?
Although so much is said about such possibilities, it is one thing for the scientists and inventors to talk game and completely another for home owners and builders to play. In order to cut home energy use, both the consumer behaviour an industry practice have to change. As we all know, construction trades are usually very conservative. Furthermore, the industry is highly fragmented and diffuse, consisting of mainly small contractors who install separate systems in homes. Nobody shows any interest in integrating the many systems with the main objective of energy saving.
