What to Ask When Considering Using Shrinkage Reducing Agents

Shrinkage reducers control drying shrinkage and minimize cracking. Terry Holland in his recent article in Concrete Construction, "Using shrinkage-reducing admixtures" suggests asking manufacturers the following:

  • What are the effects on fresh concrete?
  • What are the effects on hardened concrete?
  • What is the effect on durability?
  • Is there any information on how have similar structures behaved in service?
  • Is the same cement going to be used as in the test specimens or comparison project?
  • What is the impact on cost?

Before using a shrinkage reducing agent, ask the manufacturer how it will affect your project and materials.
