Testing Apparatus

It is used in large road construction projects has increased considerably in recent years. This apparatus, mounted on a rolled steel joint cantilevered from the back of the truck or fitted to the underside of a mobile frame, can be used to determine the bearing capacity of soils quickly and efficiency. This method of testing in-situ, using piston penetration, is useful for determining the load carrying capacity in the field, when the in -place density and water contents are such that the degree of saturation is 80% or greater. When the material is coarse grained and cohesionless so that it is not affected b changes in the water content and when the material has been in- place.

Consolidation test is un-dimensional test considered extremely important in soil mechanics. Sample taken from adjacent areas of a single site show differential settlement even when tested using same techniques. Soil of similar strength may show varying consolidation. Samples are very carefully prepared and vertical settlement of the specimen in saturated or drained conditions carefully recorded when known load is applied.

The apparatus is used to determine the work ability of Portland cement & concrete. The Kelly ball test is considered to be simple and much faster than the slump test.Twice the Kelly ball reading approximately equals the slump. It consists of a cylinder with a ball shaped bottom and handle. A strip frame, guides the handle and serves as a reference for measuring the depth of penetration. The handle is graduated in mm.

Consists of slump cone fitted with handles and foot pieces in position. Base plate in octagonal shape two clamps slide over the foot grips of a standard slump cone and hold it securely while filling and rodding. A Combination swivel carrying handle. Complete with graduated temping rod 0-60cms long and 16mm dia with 0-30cms scale graduation.
