The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The oven dried and accurately weighed aggregates are subjected to crushing test on compression testing machine and weight of the resultant fines passing the specified IS sieve to the total weight of the sample expressed a s a percentage is defined as Aggregate Crushing Value. The apparatus is available in three size 75mm dia for 1/8” to ¼” size aggregate, 150mm dia for 3/8” to ¾” aggregate (standard) and 300mm dia for 1” to 2” aggregate.

The aggregate impact value of coarse aggregate provides a relative measure of the resistance of an aggregate to sudden shock or impact. The oven dried and accurately weighed aggregates are subjected to a total of 15 blows of specified weight and fall and percentage of fines formed in terms of the total weight of the sample is expressed as the aggregate impact value.

Consists of a rigid support frame, incorporating a water tank mounted on a platform. A mechanical lifting device is used to raise the water tank through the frame height immersing the specimen suspended below the balance. The balance supplied may also be used as a standard weighing device, thus providing a versatile and comprehensive weighing system in the laboratory. WEIGHING IN AIR AND IN WATER FRAME : Consisting of a rigid frame, water tank, and cradle.

This test covers determination of the density of freshly mixed concrete and gives formulas for calculating the yield, cement content, and air content of the concrete. Yield is defined as the volume of concrete produced from a mixture of known quantities of the component materials. Bulk density is determined by filling a container of known volume and mass of concrete required to fill the container divided by the volume.

Used for specific gravity and water absorption test of aggregate. The basket is used in conjunction with a suitable electronic balance, a specially designed robust frame to support the electronic balance and water tight container. The Density basket is of 20cm dia x 20cm high fitted with galvanized wire mesh of 6.3mm with handle for suspending it from the balance.
