www.fdot.govand retarding admixture is used, meet the requirements of a Type D. 346-2.5.2 Air Entrainment Admixtures: Use an air entraining admixture in all concrete mixes except counterweight and dry cast concrete. For precast concrete products, the use of air entraining admixture is optional for Class I and Class II concrete.
ConCrete Sampling and teSting - Precast
precast.orgAir tests determine the total content of entrained and entrapped air in concrete. During batching and mixing tiny air bubbles are created in the concrete mix. If the concrete contains an air-entraining admixture, these bubbles remain stabilized in the mix due to the electrostatic binding of air, water and cement. In

wisconsindot.gov501.2.5.2 Air-Entraining Admixtures (1) Furnish an air-entraining admixture on the APL, or provide a certified report of test or analysis showing the air-entrainer conforms to AASHTO M154 for 7-day and 28-day compressive and flexural strengths and resistance to freezing and thawing. The engineer will not require tests for bleeding and setting time.
Test 1 : Standard Slump and Flow Table Tests
www.columbia.eduMB VR, an entraining air admixture, is used mainly to increase resistance to damage from freezing and thawing. The manufacturer claims that it also improves plasticity and workability. Pozzolith 400 N, a high-water-reducing admixture designed to produce concrete with a high workability is also added.
