Abstract: Chemical admixtures have impacted modern concrete technology more than any other
development from the last 30 years. Most notably, the introduction of polycarboxylate (PCE)
superplasticizers, viscosity-modifying agents, early strength enhancing (seeding) admixtures
and self-healing agents present substantial technological break- throughs which for the first
time allow us to formulate concrete exhibiting extremely long slump retention (6+ hrs) at no
sacrifice of early strength, ultra-high strength concrete (UHPC), self-compacting and self-
levelling concrete (SCC), self-healing concrete and extremely durable concrete. The
properties of these admixtures are described in detail. Furthermore, technology gaps existing in
the field of admixtures for UHPC are identified and an outlook into potential future
developments is attempted.
