Presentation of PhD work


Sustainable development is important to the global environment and human development. Due to the high demand for concrete production, the construction industry is responsible for about 7% of global CO2 emissions. Besides, it is estimated that about 37.5 billion tons of aggregate are consumed annually around the world and a large amount of construction and demolition (C&D) waste is also generated. So, finding a way to solve these problems is very important. Therefore, her PhD research focuses on using artificial intelligence, life cycle assessment and life cycle cost assessment for development of guidelines to predict the performance, quantifying potential environmental and cost impacts of self- consolidating concrete made with RCA.
