Since 1930 more than 100,000 new chemical compounds have been
developed and insufficient information exists on the health
assessment of 95 percent of these chemicals in which a relevant
percentage are used in construction products. For instance Portland
cement concrete, the most used material on the Planet (10.000
million tons/year that in the next 40 years will increase around
100 %) currently used in around 15% of total concrete production
contains chemicals used to modify their properties, either in the
fresh or hardened state. Biopolymers are materials that are
developed from natural resources. They reduce dependence on fossil
fuels and reduce carbon dioxide emissions. There is a worldwide
demand to replace petroleum-based materials with renewable
resources. Currently bio-admixtures represent just a small fraction
of the chemical admixtures market (around 20%) but with
environmental awareness for constituents in construction materials
generally growing (the Construction Products Regulation is being
enforced in Europe since 2013), the trend towards bio-admixtures is
expected to continue. This book provides an updated
state-of-the-art review on biopolymers and their influence and use
as admixtures in the development of eco-efficient construction
materials.
