This presentation reviews variation in raw materials and how these changes are likely to result in changes in concrete strength and workability and consequently, to some extent at least, to changes in placement. Of course, some changes may be for the better, but unless they are maintained consistently the result will be variability in the production of concrete. Concrete variability is the result of a range of factors, a few of which are explored in detail in this presentation.

  • Variation in cement
  • Variation in SCM's
  • Variation in aggregate
  • Variation in admixtures
  • Variation in testing
  • Variation in statistical analysis
  • Variation in standards
  • Variation in test procedures
