Compaction Factor Apparatus

BIS-5515-1983 For determination the workability of concrete provided the nominal maximum size of the aggregate does not exceed 38mm. This is designed primarily for use in the laboratory but in suitable circumstances, it may also be used in the field. This test is more precise and sensitive and is particularly useful to concrete mixes of very low workability such as are normally used when concrete is to be compacted by vibration. Consists of two hoppers and a cylinder mounted on a rigid frame. The inside surfaces are machined smooth. The whole apparatus is furnished in hammertone spray.
