Abstract:
Concrete is the most widely used construction material in the world, and with the ever-increasing population, the use of concrete is expected to increase substantially. The environmental impacts of using concrete as a construction material are significant, ranging from the CO2 emitted during its production and transportation, to the disturbance of virgin land for the extraction of raw materials from which it is produced. Therefore, there is a great need for alternative green materials for use in construction. Furthermore, if these green materials are generated from common waste streams, the environmental benefits are twofold: it will reduce the impact from the manufacturing of building materials and reduce the stockpiling of common waste products. This project realized both of these benefits through the use of fly ash as a replacement for 100% of the portland cement in concrete and the use of recycled pulverized glass as a replacement for traditional aggregate. This paper highlights significant findings from a research effort conducted at Montana State University (MSU) focused on the use of 100% fly ash concrete with recycled glass aggregate. This material was tested to investigate its suitability for construction applications and the applicability of existing design procedures. The material proved promising with respect to its fundamental engineering properties, durability, and structural performance.
