Our Products
Our Complete range of products are California Bearing Ratio Apparatus, Ductility Testing Apparatus, Jolting Apparatus, Longitudinal Compressometer and U Shape Box Apparatus.
The California Bearing Ratio Test, (usually called CBR test) is an empirical penetration test for evaluation of mechanical strength of natural ground, subgrades and base courses beneath new carriageway construction. It is to determine the relative bearing ratio and expansion characteristicsThe apparatus confists of

IS 1208-1058, ASTM D 113, IP32, 55, AASHTO T 51 Designed to test three specimens simultaneously. The machine consists of a carriage moving over a lead screw. An electric motor driven reduction gear unit ensures smooth constant speed and continuous operation. The entire assembly is mounted with a stainless steel lined water bath completely encased in metal bound hardwood. It is equipped with an electric pump circulator and heater. The temperature is controlled thermostatically. Two rates of travel i.e. 50 mm/min and 10 mm/min are provided. Suitable for operation on 230 V, 50 Hz, Single Phase, A.C. supply.
Complete With:
MSI 4025-A Ductility Mould, with Base Plate 3 Nos.
MSI 4025-B Thermometer IP 38° C, Range: 23° C to 27° C
The jolting apparatus consists of a rectangular table rigidly connected by two support arms to a spindle at a horizontal
distance of 800 mm from the centre of the table. There is a projecting lug with a plane face on the upper face of the
table beneath which is a stop with a rounded upper surface. The table can be raised and allowed to fall freely on the stop by a cam which is connected to a motor and gearbox through a V-belt an pulleys. The cam rotates at a rate of 60 Rev/Min. A stroke counter fitted with micro-switch is provided which stops the machine after 60 Jolts. Locating pins are provided for mounting the mould compartments on the table. The mould surmounted by the hopper can be clamped rigidly to the table. Supplied complete with mould and hopper. Suitable for operation on 230 Volts, Single Phase, A.C. Supply.
A Digital Preset Counter can be supplied at an extra cost. Spares and
Accessories :
(1) Steel mould with base plate having three compartments each having 40 x 40 x 160 mm, internal dimensions.
(2) Apparatus for de-moulding the specimen.
ASTM C 469
It is designed for finding out the deformation and strains on 150 mm. Diameter and 300 mm high cement and concrete cylinders when subjected to compressive loads.
Specification:
Consists of a frame with a bottom ring and a top ring with tightening screws to firmly clamp the compressometer over the cylinder. A dial gauge .002 mm x 5 mm is mounted on the upper ring and the tie of the dial gauge rests on an anvil. The zero on the dial gauge can be set by adjusting the anvil 51
screw. Supplied in a wooden carrying case.
