Lecturer of Vietnam Aviation Academy researching roadbed construction using waste fly ash

On the morning of January 25, 2024, MSc. Nguyen Van Hoa (Lecturer of the Faculty of Construction, Vietnam Aviation Academy) reported to the Univeristy-level Acceptance Council on the topic “Research on the use of waste fly ash in roadbed construction“. Dr. Nguyen Thanh Dung – Deputy Director of Vietnam Aviation Academy chaired the council.

Nguyen Van Hoa reported the project to the Grassroots Acceptance CouncilAccording to many studies, fly ash is also considered a green material with many advantages such as: relatively high tensile strength, low shrinkage, good acid resistance, high temperature resistance, low production cost, etc. Therefore, the research on the application of fly ash in the production of construction materials solves both problems, both protecting the environment and creating a premise for sustainable development of the construction industry, creating a new step forward for the material production industry.

The project focuses on research on fly ash combined with sand and Alkali solution (using geopolymer technology) with optimal mix proportions, cured at room temperature, suitable for roadbed construction, especially the base layer, which is a minimum layer of 30cm below the pavement structure.

After listening to the project leader report on the research results, members of the acceptance council gave comments, contributions and counter-arguments. Accordingly, the Council highly appreciated the research results of the project because of its practical research direction, tight structure, and scientific content. However, the Council also pointed out some limitations of the topic for the group to continue to improve and expand the research scale.

Concluding the topic acceptance session, the Chairman of the Council, on behalf of the acceptance council, summarized and announced the score of the acceptance council. Accordingly, the project “Research on the use of waste fly ash in roadbed construction” was unanimously approved by the Acceptance Council with the assessment result “Passed”.
