Compaction Factor Apparatus Compaction Factor Apparatus – Laboratory Equipment The apparatus is used for determining the work-ability of fresh concrete, provided the maximum size of the aggregate does not exceed 38 mm. The test is particularly useful for concrete mixes of very low work-ability where true slump values are not reliable. The apparatus consists of two conical hoppers having a hinged trap door attached to the lower end of each hopper. Allowing the concrete sample to flow freely into the cylindrical mould. The hoppers and the mould are mounted onto a rigid steel frame and are easily removable for cleaning. Salient Features It consists of two rigid conical hoppers and a cylinder mounted on a rigid metal frame. The lower openings of the hoppers are fitted with hinged trap-doors having quick release catches. A circular metal plate is provided to cover the top of the cylinder. Supplied complete with one plaster’s trowel and one tamping rod, 16 mm dia x 600 mm long, one end rounded. Specifications: Size: 16 mm x 600 mm long Maximum size of aggregate: 38 mm
