Stabilization of Recycled Base Materials with High Carbon Fly Ash Civil Project
This is a good Civil engineering project report on "stabilization of recycled base materials with high carbon fly ash". Fly ashes produced by several power plants in United States occasionally contain significant amounts of unburned carbon due to common use of low nitrogen-oxide and sulphur-oxide burners in recent years. This ash cannot be reused in concrete production due to its reactivity with air entrainment admixtures and is being land filled at large percentages.

In this project, a study was carried out to stabilize low stiffness avenue floor material with excessive carbon fly ash. The non-cementitious Maryland fly ash changed into activated with some other recycled material, lime kiln dust (LKD). California bearing ratio (CBR) and resilient modulus exams were carried out to decide the power and stiffness, respectively, of the stabilized materials.

Addition of LKD and curing of specimens generally increased CBR and summary resilient modulus (SMR) and lowered plastic strains, CBR increased with increasing CaO content as well as with CaO/SiO2 and CaO/(SiO2 + Al2O3) ratio of the mixtures; however, these parameters could not be correlated with the SMR.
The unpaved road substances stabilized with LKD and fly ash is expected to lose 31 to sixty seven% in their initial moduli after twelve cycles of freezing and thawing. Maximum of the factor considered on the thickness of the bottom layer and cost calculations.
