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.
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
