Has anyone worked with or have performance data regarding substituting fly ash for portland cement in augercast grout? I am looking for shrinkage, modulus of elasticity, strength gain, etc.
All the ACIP piles that I have installed used a fly ash grout. Alas I do not have access to that data anymore. However, you should be able to contact an ACIP installer, such as Berkle or Barcus and get what you are looking for.
