DESCRIPTION:In conventional design of concrete structural elements\, the s
 ame concrete mix is used throughout a given element. This can lead to regi
 ons of unutilised material and a conservative coverage of non-controlling 
 material properties. Efforts to produce metrics that describe the efficien
 cy of constituent materials in concrete demonstrate that better use of nor
 mal concrete mixes can be exploited. However\, the predominant focus of de
 sign methods towards achieving a minimum compressive strength makes multi-
 criteria optimisation of the non-controlling properties difficult to targe
 t.\nVarying the concrete mix design within an element to achieve spatially
  variable structural and durability demands presents an opportunity to red
 uce the total cement content used within a concrete element and thereby re
 duce associated economic and environmental costs. The factors which may af
 fect the compatibility between casting layers of different concrete mixes 
 are being explored experimentally to understand the boundaries within whic
 h deterioration mechanisms are not unintentionally proliferated.\n
