Latex-modified mortars (LMM) and concretes (LMC) were developed to minimise or to completely eliminate the weaknesses of portland cement mortars and concretes. Because of this improved performance, latex modified mortars and concretes are being used increasingly in bridge-deck overlays, in repair and rehabilitation work, and in the construction of new pavements, garages, marine facilities and tunnel and pipe linings. Basic information about the characterization of LMM and LMC are presented in this synthesis, together with past applications and performances, and prospective new applications. It is concluded that LMM and LMC, particularly SBR latex modified concrete for bridge-deck overlays, are safe, durable, beneficial and economical. There is an urgent need to develop standards, specifications and guides for use.
