We are leaders in the market for providing best range of Stripping Value Apparatus, Vicat Needle Test Apparatus Automatic Recording-, Gillmore Needle Apparatus, Vicat Needle Apparatus with Dashpot and Digital Blain Air Permeability Apparatus
Stripping Value Apparatus Bitumen and tar adhere well to all normal types of aggregates provided they are dry and are not exceptionally dusty. This problem of stripping is experienced only with bituminous mixtures, which are permeable to water. This test gives the procedure for determination of the stripping value of aggregates by static immersion method, when bitumen and tar binders are used.
A circular tray rotates in a vertical plane at a rate of approximately 100 R.P.M. by an electrical geared motor. 4 bottles of approximately 400 cc are mounted on this circular tray at an angle of 900. To each other with their mouth towards center of the tray. A time switch is provided. Suitable for operation on 230 V A.C. Single Phase.
Stripping Value ApparatusBitumen and tar adhere well to all normal types of aggregates provided they are dry and are not exceptionally dusty. Thermostatically controlled water bath.

The Vicatronic apparatus, that is designed and manufactured using the most recent and sophisticated technology, is used for the initial and final setting time determination of cements or mortar pastes.The unit is manufactured with anticorrosion and tropicalised components to be used in places with humidity not below 90% and 20C. controlled temperature as required by EN Specifications.The entire test is made in a fully automatic way and gives a very precise and repeatable result.The results are printed on the incorporated printer and this eliminates the manual operations of installing and zeroing the paper graph on the drum.The use of the appliance is extremely simplified by the guiding menu that is available in english, french, spanish, german, italian language.

Gypsum plaster, lime etc. As per ASTM C 187-58 C 472-62 C 110-58, IS 2542(Part-1) can also be supplied.
he fineness of cement has a significant effect in its physical properties when used in concrete. Generally the finer the cement powder, the more rapid the concrete will set, as there is an increase in its surface area. The measure of fineness is usually undertaken by sieving, and the result assessed against the cement standard for compliance.
The Blaine air permeability apparatus is used to determine the fineness of Portland cement in terms of the specific surface expressed as total surface area in square centimeters per gram of cement. The Blaine apparatus draws a defined volume of air through a prepared bed of cement of defined porosity.
The apparatus comprises one each of Brass or stainless steel permeability cell 12.5mm, U tube manometer with stop cock mounted on a laminated wooden stand, perforated metal disc, plunger, Rubber stopper, Rubber tube 30cm long with rubber bulb.
Optional AccessoriesAt extra cost
Soil Permeability Apparatus come with glass tubes of 75mm, bore tube is provided with over flow arrangement for constant head tests. The remaining tubes are used for falling head test.
