Fly ash clay bricks are manufactured with clay and fly ash—a byproduct of coal burning—fired at about 1,832 degrees Fahrenheit. This type of brick is sometimes described as self-cementing since it contains a high volume of calcium oxide and expands when exposed to moisture. This tendency to expand, however, can also produce pop …

It has been used by LEED architects in well know projects such as ...

One of the reasons fly ash is so popular as an additive, of course, is that there's a lot of it left behind by coal plants. At the same time, one big point in favor of fly ash's use in concrete and brick is the idea that a chemical reaction is believed to effectively trap any minute levels of fly ash pollutants within the building material.

The thermal conductivity of fly ash bricks is 0.3 – 0.4 W/m K. 7. Sound Insulation: 40 – 45 dB sound is reduced by a 200 mm thick AAC block. 37 – 39 dB sound is reduced by 100 mm thick brick. 8. …
