DOI:https://doi.org/10.2172/6089691· OSTI ID:6089691
The Coal Research Bureau of West Virginia University, under contract to the Department of Energy, has developed a process for producing fired structural products from flyash and bottom slag, both of which are recyclable minerals produced in electric utility boilers. All of these fired structural products meet or exceed American Society for Testing and Materials specifications for facing brick. A study has been completed to reduce the weight of the fired structural products by replacing the bottom slag with lightweight flyash aggregate. The use of lightweight flyash aggregate in flyash brick results in a brick having a significantly reduced bulk density. The resulting lightweight flyash brick possesses many desirable qualitites, perhaps the most important of which is the improved thermal insulating characterisitics.
