This tests purpose is to get the air content of a sample of concrete using a pressure meter. In the meter you have a known volume of air at a known pressure in a sealed air pot with an unknown volume of air being contained inside the sample of wet concrete. You set it to the percentage of air (your initial pressure) where the pressure is equalized inside the chamber, fill it with concrete and water so that the only air left is the air inside the concrete, and then release the pressure inside of

finding the root cause of the air content discrepancy observed in concrete made using synthetic AEAs. A laboratory program at multiple scales including concrete air void analysis, the foam drainage test, and fundamental tests for micro-properties of individual bubble shells was conducted. The results showed that the air bubbles in concrete

aluminium plate. The concrete surface may be pre-dried with hot air, ensuring, however, that the temperatures remain below 120 °C. Higher temperatures could already lead to micro damage in the concrete. Fig. 1: Laboratory test setup (Disk test), the Fig.2: On-site test setup (Packer test)

Aug 20, 2018 · This test is made possible by an equipment which is known as Rapid Chloride Permeability test equipment, The test equipment consists of two reservoirs. One of them has 3.0% of NaCl solution and another reservoir has 0.3M NaOH Solution, Concrete having thickness 50mm and dia 90-100mm is used as a test specimen.
