    Internal Curing with Fine Line Weight Aggregates

    The purpose of this project is to analyze and test a potential alternate to current FLWA's using previously unsuitable Fly Ash (SPORA LWA). The new proposed material has the potential to contain heavy metals, and as such, testing as to the deterioration and release of these potential hazards must be addressed. The material, if found to be stable after partial deterioration and rubblization, would then be tested to assess its potential as an alternate to current FLWA's. 

    Design - Project No: Drexel WO 001

     Anticipated Outcomes:

     

    A report on the topic of using unsuitable coal fly ash/bottom ash to create a stable Lightweight aggregate material. Included in the report is to be:

    • Testing of the physical properties of the manufactured material
    • Testing of material related to potential environmental risk using contaminated/unsuitable base material
    • Performance testing of the material as a lightweight aggregate related to internal curing
    • .

      The report will also include a write-up related to lowest life cycle cost and the potential incorporation of the manufactured aggregates for internal curing.
