In this fast-developing world, it has become important for civil engineers to focus both on global developments and the impact on the environment. This approach leads to innovations and research on conserving the environment without compromising on the developments. One such innovative technology is the geopolymer concrete - an eco-friendly technology that makes use of waste byproducts like fly ash, ground granulated blast furnace slag, etc., from various industries, in the preparation of concrete, instead of the Ordinary Portland Cement (OPC). The evidences from various researches show that using OPC in the preparation of concrete leads to almost 5-8% of the man-made global carbon-dioxide emissions, while using materials like fly ash and GGBS reduces carbon-dioxide emissions by 90%.
The seminar started with a keynote address by N.P Rajamane, who also shared comparisons between concretes made using Geopolymer and Portland cement as binders. This was followed by lectures on the following topics by eminent speakers:
- Geopolymer: An Alternative Binder, by Dr. R V Ranganath
- Geopolymer composites to cater to the needs of costal areas producing the same by using marine water, by Dr. T. Venu Madhav
- Development and application of Geopolymer masonry, by Dr. Radhakrishna
- Applications of Geopolymer Concrete, by Prof. SK Singh.
