The complexity of high performance concrete (HPC)
mixture designs continues to increase, along with the
number of criteria that a particuhu mixture must
satisfy. Robust statistical methods exist that can be
used to not only determine the mixture for a concrete
that meets specifications, but does so while satisfying
a number of additional user-specified constraints. Two
such techniques are the mixture method and the response
surface method of experimental design. These techniques
are discussed and compared. Future developments in
concrete mixture optimization based upon materials
science-based models are discussed.
