"This handbook is a great impetus for an accelerated commercialization of an eco-friendly alternative binder technology with more in-depth understanding of its strength, weakness, opportunities and threats...will go a long way to fulfil the essential requirements of transferring the technology from the laboratory to the field." --Dr Anjan K. Chatterjee, Fellow of the Indian National Academy of Engineering and Chairman of Conmat Technologies Pvt Ltd., Kolkata (From the foreword)
This book provides an updated state-of-the-art review on new developments in alkali-activation. The main binder of concrete, Portland cement, represents almost 80% of the total CO2 emissions of concrete which are about 6 to 7% of the Planet’s total CO2 emissions. This is particularly serious in the current context of climate change and it could get even worse because the demand for Portland cement is expected to increase by almost 200% by 2050 from 2010 levels, reaching 6000 million tons/year. Alkali-activated binders represent an alternative to Portland cement having higher durability and a lower CO2 footprint.
