Introduction to Handbook of Alkali-activated Cements, Mortars and Concretes
Abstract: This chapter starts with an overview on relevant AACB landmarks and also on AACB problems. Important bibliographic events as well as recent progress in this field are reviewed. Some shortcomings concerning durability performance, carbon footprint and efflorescence are reviewed. Comments on the possible contributions of AACB for sustainable development and eco-efficient construction are given. These include AACB with lower carbon footprint, contribution of AACB for building energy efficiency and the capability of AACB to reuse a high waste content. An outline of the book is also given.
