Geotextiles can be cut or punctured during field installation, which can create a possible condition by which strength is controlled by a tearing resistance. An outline of an isosceles trapezoid is marked on a rectangular specimen (150 mm x 75 mm) cut for the determination of tearing strength, (with a 6 to 9 mm cut) and the nonparallel sides of the trapezoid marked on the specimen are clamped in parallel jaws of the Tensile Testing System.

This is a double lever (leverage 1:12) loading machine and the load is applied by flow of lead shots, which automatically stops when the sample breaks. The load is applied at rate of 450 to 550 N/minute ( 45 to 55 kg minute) or 2000 N/minute (200 Kg/minute) and the accuracy of load indication is ± 2%. The sample is mounted between rollers 40 mm dia or12 mm dia. Bearing Rollers can be placed at center distance of 150 mm, 200 mm, 250mm or 270mm as the case may be. Complete with 20 Kg lead shots.

The tile sample is pressed under a specified load against a grinding path, strewn evenly with an abrasive powder, revolving at the rate of 30 ± 1 rpm. At the end of 100 revolutions of the disc, the second parallel side of the tile is subjected to wear for an equal number of revolutions of the disc. The wear of the tile is measured using thickness-measuring device (which is supplied at extra cost). The abrasion-testing machine consists of a replaceable grinding path, fitted on to a disc rotating about its vertical axis. The rotating disc and the grinding path are enclosed by a circular tray. A bracket holds the specimen.

Using a speedy moisture meter, the moisture content of soils, sand and other fine-grained material can be obtained quickly with reasonable accuracy. The test technique is based on the fact that water will react with calcium carbide to form acetylene gas and the quantity of gas formed is directly proportional to the water present, leaving a surplus of the chemical used in the test. The quantity of acetylene gas produced is indicated on a built-in pressure gauge, which is calibrated in percentage of moisture on wet weight basis.   Speedy Moisture Meter Range: 0 - 25%, Accuracy Division: 1% Speedy Moisture Meter Range: 0 - 50%, Accuracy Division: 1%

Compaction : Soil compaction is a fundamental requirement for the construction of earth fill for dams, reservoirs, canal embankments, highways, railways and runways. The relationship between soil moisture content and compacted dry density is very useful for deciding construction specifications and quality control of compacted earth fill. While designing an earth or earth retaining structure, the strength and deformation behaviour of soil is evaluated by testing soil specimen compacted to the density as would be achieved during construction. The construction quality control is essentially to check the density of compacted soil achieved in the field, thereby checking its strength.

This apparatus used for determining the slump of fresh concrete as a measure of its consistency. It consists of a pressure-tight flanged cylindrical measuring bowl, fitted with a removable flanged and a conical cover assembly with a seal in-between.

Required pressure is applied to the specimen with the help of a pressure bulb. The recommended limits specified for the air content are between 3% and 6.5%.Each apparatus is supplied complete with a calibrating cylinder, pressure gauge, funnel, trowel and tamping bar.
