Presentation by Mark Mackenzie on Thermal management of concrete pavements from ASCP Forum March 2017
Accurately Estimating In-Situ Strength of Concrete
Many applications require accurate estimates of In-situ
Post tensioning – initial and final stress
Jacking jump Forms
Bridges Decks – stressing, launching, removal formwork, etc.
Lifting, delivery, etc.
Concrete Pavements – compliance, trafficking, etc.
Secant Piles – drilling alternate piles
The norm in Australia and Many Places Around the world is
to use Cylinders or Cubes
Cylinders to be cured in same environment as elements
Numerous other methods
The fact is that:
Unless “Temperature Matched Curing”, which has its own very
significant challenges and limitations, is used
Concrete cylinders Cannot and Do Not Accurately Estimate the In-Situ
Strength of Concrete
