Description

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.

Key Features

  • Reviews the chemistry, mix design, manufacture and properties of alkali-activated cement-based concrete binders
  • Considers performance in adverse environmental conditions.
  • Offers equal emphasis on the science behind the technology and its use in civil engineering.

Readership

civil engineers, contractors working in construction and materials scientists in both industry and academia.
