Further testing revealed that 1% calcium stearate reduced the amount of heavy metal leaching from fly ash. On the other hand, with 1% calcium sterate the concentration fell to 93.4ఓ௚௅.

Column leaching results revealed that the concentration of cadmium was 166 ఓ௚௅ for 3% calcium sterate. However, with 1% calcium stearate the concentration dropped to 45.5ఓ௚௅. Batch leaching results indicated that the concentration of chromium was 65 ఓ௚௅ for fly ash alone. The fly ash with the additive was evaluated by measuring the concentration of heavy metals such as Chromium, Lead and Cadmium that leached from the fly ash. The methodology involved testing fly ash with various amounts of additive. To assess the ability of the additive to solidify heavy metals, batch leaching tests and column leaching. The objective of this experiment is to evaluate the performance of calcium stearate to encapsulate heavy metals in fly ash to prevent chemical leaching. Heavy metal leaching from improperly disposed fly ash remains a concern to human health and the environment as a result of their toxicity. The different assignments, the challenges that were overcome and lessons learned. Modules, the challenges in condensing various courses into individual training modules, Is to discuss the structure of the training sessions, the material covered in the different

Modules consisted of showing the faculty the automated features in the software such asĬreating topographic surfaces from survey data, using the assembly feature to generateĬross-sections and further determine the volume of earthwork.

Multitude of iterations given the parametric nature of individual projects. The software’s automated features to enable faster design processes and allow students a Needs reliant on the course content and method of delivery. The training modules were designed to address the discipline specific Structural analysis, municipal planning, project management for engineers, and seniorĭesign capstone. Led to the training of faculty teaching courses such as highway engineering, geomatics, The industry demand and need to incorporate it into academic coursework The need to incorporate this software into various courses in theĬivil engineering curriculum is essential to ensure students are equipped with softwareĭesign skills. AutoCAD Civil 3-D is the most commonly used design software package in the civilĮngineering industry.
