Cone Penetrometer For determining the Liquid Limit of soils. This is specially useful to obtain reliable and accurate results for those soils which have low plasticity index. The percentage moisture contents determined when cone with half angle of 15-30 minutes under a total sliding weight of 148 gm penetrates 25 mm gives the Liquid Limit.

Blaine's Air Permeability Apparatus The apparatus is used for determining the fineness of cement in terms of specific surface expressed as total surface area in square centimeters per gram of cement. This is a variable flow type air permeameter. Salient Features Specifications : The apparatus consists one each of permeability cell 12.5mm I.D., Manometer 'U' type mounted on stand with a built in stop cock, Perforated disc, Plunger Rubber stopper, Rubber tube 30cm long.

Compaction Factor Apparatus The apparatus is used for determining the workability of fresh concrete, provided the maximum size of the aggregate does not exceed 38mm. The test is particularly useful for concrete mixes of very low workability where true slump values are not reliable. Salient Features Specifications : 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 compl
