Autoclaved Aerated Concrete – Using MSWI Bottom ash as an Aerating Agent
The State of Florida, in collaboration with the Hinkley Center and the Herbert Wertheim College of Engineering, has emerged as a pioneering force in the national landscape for recycling Municipal Solid Waste Incineration (MSWI) Bottom Ash (BA). These groundbreaking efforts, spearheaded by innovative research signify the state’s commitment to sustainable practices. While these beneficial use options indeed hold great promise, they represent just the beginning of a transformative journey toward a greener, more eco-friendly future.
The autoclaved aerated concrete (AAC) and waste-to-energy (WTE) industries have the potential
for a mutually beneficial relationship in the United States (US). AAC is a lightweight, cellular
cementitious building material that offers excellent thermal insulation, fire resistance, durability,
and strength relative to other building materials like wood and masonry units.
The specific objectives of this research project are as follows:
- Determine the potential for the production of AAC using MSWI BA as an aerating / expansion
agent. A specific focus will be on the use of the fine fraction of MSWI BA which is typically not
beneficially utilized in products composed of portland cement concrete. - Conduct research on the thermal transmittance characteristics of AAC due to its recognized
capacity for effective insulation. Determine the potential for AAC to experience leaching of
materials to ensure AAC produced with MSWI BA does not adversely affect the surrounding
environment. - Determine the economic feasibility for using beneficially reusing MSWI BA for the production
of AAC.
