A system of loading which causes section of a bar or shaft to rotate about its central longitudinal axis relatively to another such section and which thus produces twist or torsion in the bar, constitutes a torsional load. The load may be composed of forces acting in any direction but the twisting or torsional affect is provided by the couples formed by these forces in planes normal to the central axis. The torsional shearing stresses in circular cross section vary from zero at the axis of the section to a maximum value at the extreme fibres. If no bending is present pure shear exists. Torsion Testing machine Consists of two independent chucks. The twist is communicated through the test piece to the other jaw on which a weighted pendulum is attached. The resistance to deflection of pendulum causes a torque to be applied to the test piece and the angles of deflection of pendulum is the measure of torque. The machine is built for maximum twisting moment at about 50 kgm. It is equipped with jaws for accomo- dating test pieces of 10 mm, 15 mm and 20 mm size either square or circular with square shoulder.

The machine is used for testing crushed slag, crushed and uncrushed gravel for resistance to abrasion. The aim of the test is to find the percentage wear due to the relative rubbing action between the aggregates and steel balls as abrasive charge. The oven-dried arrangements are weighted and rotated along with abrasive charge in the machine for the 500 or 1000 revolutions and percentage of wear so found out its reported as Los angeles abrasion value.

The strength of concrete is generally estimated after 28 days by crushing field test cubes or cylinders made from the representative concrete used for the structure. The utility of ascertaining strength after 28 days is often questioned since by this time considerable concrete would have been placed and work may have progressed. It is then rather too late for remedial measures. It is therefore of tremendous advantage to predict 28 days strength within a few hours of casting the concrete so that, we have a good idea about the strength of the concrete.The rate of gain of strength of concrete depends on the reaction rate of cement and additions with water (Hydration). In common with all chemical reactions, the rate of reaction depends on reaction of temp. Higher reaction temperature gives higher rate of reaction e.g. the concrete gains strength more rapidly when its temp. is higher. Accelerated curing is the process by which the temperature of the concrete is raised artificially by applying external heat to speed up the rate of gain in strength.The test method covers procedures for curing test specimens of concrete stored under conditions intended to accelerate the development of strength. The procedures are: Procedure A- Warm Water Method, Procedure B-Boiling Water Method

The digital compression testing machine has been designed to meet the need for a simple, economic and reliable means to test concrete for its compressive strength. The design expressive of simplicity, both of construction and operation, makes the machine easy to use and maintain. The unit is compact, making it useful for site and Laboratory applications. The digital machines are provided with a pace rate controller, to enable maintain a constant of loading.
