TECHNICAL DESCRIPTION :

As entrainment of air in limited percentage improves durability of concrete and very low improves percentages deteriorate it, measurement of air entrapped in freshly mixed concrete entrapped becomes important The apparatus consists of a pressure tight flanged cylindrical measuring bowl of 0.005 cubic meter capacity for maximum size of aggregate 38mm. The bowl is fitted with are movable flanged conical cover assembly with the help of a seal. The conical cover removable help has an air valve and a petcock for bleeding off the water. A transparent cylindrical standpipe which is graduated in air content is fixed to the conical cover assembly. Pressure is applied to the specimen with the help of a pressure bulb and the pressure is recorded on the pressure gauge which is mounted on the stand pipe. The whole assembly is mounted on a flat base. The instrument is supplied complete with one each following follow accessories.
