Capping Set

For correct compressive strength of concrete cylinder, the end surface of the specimen must be truly flat.If They are not, using capping compound and a capper, the face are plastered flat. capping set can be used for cylindrical specimen like concrete cylinders or cores. they can be used in laboratory or in filed.They applies Horizontal and Vertical.

for 15 cm dia x 30 cm length cylinders / for 100 mm dia x 2000 mm length cylinder.

is used both in the laboratory and in the filed. The specimens capped in this apparatus have plane parallel faces.

Specification and design are subject to change.

Vibrating Table

is used for compacting concrete cubes and cylinders.

.Its design to carry a load of 140 kg. the Table top is 50 cm x 50 cm and has stops along to prevent moulds from walking off the table during vibration.Vibration are between 3600 - 2600 per minute

Note :- Table Top Size 75 cm x 75 cm as well as 100 cm x 100 cm are also available.

Vibrating Machine

Concrete moulds are easliy cast by using a tamping table. However air trapped in cement mortar paste can not be thus removed while casting cement mortar cubes.Easy method is to impart greater vibration of lesser amplitude to yhe mould while casting. this is achived in a Vibrating Machine.

Vibrating Machine is used for the preparation of mortar cubes for the determination of compression strength of ordinary and rapid Hardening Portland Cement, low heat portland cement,portland blast furnace cement and high alumina cements.

Compression Testing Machine

strength of concrete is a very important aspect during constrution. Strength of concrete is obtain by crushing the specimen in the form of cubes or cylinders. Concerete is carefully designed for a particular compressive strength by Engineers and Specimen is tested by applying load in a compression Testing Machine.

manufacture a range of Compression Testing Machine From 10 Tonnes to 200 Tonnes in different models. Portable models are very convenient and useful for site use where carrying frequently the specimens for testing in a standard laboratory is inconvenient and uneconomical.

With special attachment, the machine can also be used for bricks, hallow or solid concrete blocks, using appropiate capacity machine.

In general a Compression Testing Machine Consists of a load Frame with Suitable platens and a Pumping Unit with Pressure Gauge, either hand opreated or electrically-cum-hand operated. Load Frame and Pumping unit are connected by pressure pipes.

Concrete Test Hammer

The is an instrument which is easy to use and approximate measurement of the resistance to pressure of manufactured concrete products.the principal on which it works are based onthe rbound impact of a hammer on a piston which rests againts the surface of the concrete products.The Graeter theresistance of the concrete, greater is the rebounded impact.By reading this rebound impact on a scale and relating it to curves on graphs supplied with the instrument, the resistance to compression in MPa or PSI can be fund, with +/- 20% of actual.
