It is used for finding out the rate of hardening of mortars sieved form concrete mixtures, by means of penetration needles of different cross-sectional areas.   

 

Specification:

The instrument consists of a barrel housing a calibrated spring and a stem graduated from 0- 70 kg X 1 kg. Six interchangeable penetration needles of areas 645, 323, 65, 32 and 16 mm sq. are provided.

 

The penetration resistance is measured by the force exerted to penetrate the mortar by 25 mm and is indicated by a sliding ring on the stem, which is graduated.

 

Needle shanks are marked at every 12.5 mm. Compete in a wooden carrying case.

 

It is used for fast evaluation of the initial setting of concrete. It can be used on light-weight concrete, special roof deck mixes and concrete additives.  

 

Specification:

Consists of a needle having face area 3/10 sq. cm. and graduated at a distance of 25 cm.

The needles point is an integral part of barrel which houses a calibrated spring.

The spring is confined in a sleeve.

The resistance offered by the concrete mortar is shown on the direct reading scale with a marker ring which holds its position when released.

Scale range is 0-50 kg/cm when the penetration resistance reaches a value of 35 kg/ cm2 the concrete is assumed initially set.

Supplied complete in wooden carrying case.

 

The instrument is used for workability as well consistency of fresh concrete. A slump cone and a graduated rod supplied with the instrument helps the operator to find out slump values and Vibration Table with container and acrylic disc. It is used to find outwork-ability of concrete expressed in Vee-Bee degrees, which is defined as the time in seconds to complete required vibrating at which the fresh concrete flows out sufficiently to come in contract of the entire face of acrylic disc.   

Specification:

The equipment consists of: A vibration Table size 380mm long and 260mm wide, resting upon elastic support at a height of about 305mm above the floor, complete with start/stop Switch, Cord and Plug.

A holder is fixed to the base into which a swivel arm is telescoped with funnel and guide sleeve.

The swivel arm is also detachable from the vibrating Table.

A graduated rod is fixed on a swivel arm and at its end a plastic disc is screwed.

The divisions of scale on the road record the slump of the concrete in millimeters.

Supplied complete with a sheet metal container with lifting handles which can easily be fixed to the vibrating Table.

A slump cone open at both ends with lifting handles and a Tamping rod of size 16mm dia and 600 mm long, rounded at one end.

 

It is used for the determination of the consistency of freshly mixed concrete, where the maximum size of the aggregate does not exceed 38mm.    

Specification:

The apparatus consists of one slump cone with handles and foot pieces.

The Slump cone has internal dimensions 20cm. dia. At base 10cm. top dia. and 30cm. height. Foot pieces can be fixed to the clamps on the base plate.

The base plate has lifting handle for easy transportation. One graduated steel rod 16mm dia. x 600mm long, rounded at one end and graduated in mm, is also supplied.
