Concrete Testing Equipment
Extensometer Extensometer Introduction The unit consists of two movable frames pivoted at one end. The lateral extensometer is fixed to the specimen with the help of tightening screws. The lateral extension is indicated on a dial gauge of 0.002 mm x 12 mm travel. The extension is magnified 2.5 times and the dial gauge readings …
Cylindrical Molds Cylindrical Molds Introduction 10cm x 20cm Made of Cast Iron – with base plate 15cm x 30cm Made of Cast Iron – with base plate
Cube Mould Cube Mould Introduction Cubes of fresh concrete are made to test a variety of properties on the eventually cured and hardened concrete. Fresh concrete is subjected to a standard compaction regime in the cube mould and is then normally initially cured under specific laboratory conditions. The moulds are manufactured, subject to tight dimensional, …
Compaction Factor Apparatus Compaction Factor Apparatus Introduction 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 …
Air Enterainment Meter Air Enterainment Meter Introduction 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 …
Accelerated Curing Tank Accelerated Curing Tank Introduction The strength of concrete is generally estimated after 28 days by crushing field test cubes or cylinders made from the representative concrete used for the structure. The utility of ascertaining strength after 28 days is often questioned since by this time considerable concrete would have been placed and …
Concrete Penetrometer Concrete Penetrometer Introduction This test is used to determine the elapsed time between batching of a concrete sample and when it is deemed by standard methods to have set. The method involves measuring the penetration resistance of a test sample, which has had coarse particles removed at periodic intervals. It is particularly useful, …
Concrete Mixer – Laboratory Type Concrete Mixer – Laboratory Type Introduction A concrete mixer is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete. The mixer uses a revolving drum to mix the components. Uniform and thoroughly mixed batches can be produced in field or Laboratory. Inevitable …
Compression Testing Machine – Hand Operated Pillar type Compression Testing Machine – Hand Operated Pillar type Introduction This machine is quite useful on field Laboratories or mobile testing laboratories or Vans which frequently change site or location. It is particularly useful where constant and consistent Electric power is not available. The load is applied manually …
