Energy efficient bricks created

Smart bricks have been created from clay, glass and coal ash.

Australian scientists have developed bricks made from clay and waste and called them "energy smart". The study was published in Construction and Building Materials.

Conventional bricks used in construction are fired at very high temperatures, thereby releasing enormous amounts of carbon dioxide into the atmosphere. Smart bricks are created by mixing clay, glass waste and coal ash. According to experts, their firing requires a much lower temperature; also, such building material retains heat well in winter and does not overheat during hot weather.

Scientists have calculated that a temperature of 1050 degrees is required to fire ordinary bricks, and 950 degrees for smart bricks. The material also states that savings will be noticeable and harm to the environment will be reduced if manufacturers produce 1.4 trillion of the new type of bricks per year.

According to experts, bricks have low thermal conductivity, so they retain heat in winter and prevent overheating in summer. Thanks to this, consumers will be able to save on electricity for heating or cooling rooms. Also, the strength of the new bricks meets international standards.

At the end of June, Korean scientists developed a method for creating bricks from lunar regolith using microwave sintering. This method is similar to ceramic firing and involves raising the temperature of raw materials to create solid building materials.
