- Air content of fresh concrete is normally measured, by the use of a special air meter, to assess whether the concrete contains the required amount of air. This would be measured when air’s entrapment or entrainment is required by the concrete design. The method uses the principle of replacing the air in a known volume of concrete with water, the…

- The compaction factor is defined as the ratio of the mass of the concrete compacted in the compaction factor apparatus to the mass of the fully compacted concrete. It involves dropping a volume of concrete from one hopper to another and measuring the volume of concrete in the final hopper to that of a fully compacted volume. The results of…

- Vee bee test is the pure laboratory test to measure workability of fresh concrete. The workability of fresh concrete is defined as the amount of useful internal work necessary to produce 100% compaction. Vee bee test gives the time required to achieve compaction, which is related to the total work done; hence vee bee test is a good test to…

- The Vibrating Table produces better concrete Moulds and cylinders by removing entrapped air. It distribute concrete evenly inside the moulds and nearly eliminate the problems of bug holes and air bubbles.
