Corrosion of Prestressed Concrete beams and Alkali activated concrete
Cement-based concrete was the key commodity for various structures and buildings until recent years. Since the last decades, though conventional Portland cement is safe and durable for its design, sustainability has become a significant challenge to the construction industry (1). The cement industry sector is a significant contributor to greenhouse gases (2). It was calculated that a ton of CO2 is being emitted to produce 1 ton of cement, resulting in 7% of global CO2 emissions. Another environmental issue confronting today's researchers is the depletion of natural resources due to OPC (3). On the other hand, the various by-products from industries and agriculture, such as GGBS, fly ash, metakaolin, rice husk ash, etc., which can replace cement in the concrete, are facing disposal/landfilling problems. To reduce these adverse effects on the environment and fulfil the sustainability criteria, new binding materials that perform nearly equal or better than cement with low carbon footprints are preferable (4). Hence the potential use of these SCMs can make concrete sustainable. Currently working on Alkali activated cement concrete and corrosion of Prestressed Concrete beams
