Concrete with polymers

Many aspects of concrete have been researched and published over the last few years. Many books have covered the properties, applications and more recently about the durability of concrete. Eco-efficient concrete will look at many different types of concrete and the environmental performance of each type whilst using the latest research on this subject. The first part of the book analyses concretes based on new chemistry cements (sulfoaluminate and magnesia cements) associated to low CO2 emissions. The second part the moves on to analysing concretes that have been partially replaced with Portland cement and discusses pozzolanic activity or hydraulic properties. This chapter describes the use of different polymers, added in fresh or hardened hydraulic cement or to replace the cement. The introduction of polymers, in or with concrete, is able to modify its characteristics and properties, to protect or to repair concrete elements.
