The Crushing strength or compressive strength is given by the formula as: C= P/A. Where, C = compressive strength. P = Load at failure. A = crosssectional area of bearing face of
Many of the known building stone & rock tests are explained briefly below: 1. Hardness test. Hardness is the resistance of a stone to indentation,

Test for Stones. (a) Crushing test for stones: The crushing strength of a stone greatly depends upon its texture and specific gravity. A stone of even texture arid of specific gravity greater than 2.7 can take heavy loads. Safe compressive loads on stones should be taken not more than onetenth of the crushing loads determined by cube test.
Crushing test on stones. The crushing test gives the strength of the stones. These tests are performed for stones to be used at the bottom of heavy structures. For this test, cut the stone specimens into 40mm x40mmx 40mm and dress the sides. Minimum of three specimens are needed for this test.
Procedure The aggregate sample: The material for the standard test consists of aggregates sized 10.0 mm to 12.5 mm.The aggregates must be in a surface dry condition before testing. The

The more compact grained and heavier a stone the harder it is. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 3040%. Being dry stones allow more crushing strength than when wet. It is the ability of a stone to endure and maintain its essential and distinctive characteristics i.e. resistance to
Stones tests for durability of natural building stones. At least three test pieces, each 50 mm cubes or 50 mm dia cylinders of 50 mm height shall he dried for 24 hours and weighed (W 1 ). The test pieces are then suspended in a saturated solution of sodium sulphate decahydrate for 18 hours at room temperature 20 to 30°C.
The testing procedure to determine the aggregate crushing value typically follows the testing standard BS 812–110: 1990 Discrete element modeling of the singleparticle crushing test for ballast stones. Comput Geotech, 88 (), pp. 6173. Article. Download PDF View Record in Scopus Google Scholar.
For this purpose, detailed crushability tests were carried out on four different rock types to assess their degree of rock crushability (DRC). Various feeding sizes (9.5 19 mm) and quantities

In a crushing test machine, the load is imparted axially to the cube. The loading rate is 140 kg/sq.cm/min. The greatest force at which the sample crushes or fails divided by the area of the bearing face of the specimen is the crushing strength of the stone per unit area. In a test on construction stone, an impact testing machine is

Aggregate Crushing Value Apparatus. A 15 cm dia. Steel cylinder with plunger and base plate. A straight metal tamping rod 16mm diameter and 45 to 60 cm long rounded at one end.; A Weigh balance of accuracy up to 1 gram.; IS sieves of sizes 12.5 mm, 10mm, and 2.36 mm.; A compression testing machine.; Cylindrical measure having a diameter
Crushing Value Test Procedure. Select clean and dry aggregate passing through 12.5 mm and retained on 10.0 mm sieve. Weight the empty cylindrical measure. Let the weight be ‘a’ grams. Fill the aggregate in the cylindrical measure in three layers, tamping each layer 25 times with the rounded end of the tamping rod.

The building stones are to be test for their different properties.Following are such tests for the building stones : Acid test. In this test, a sample of stone weighing about 0.50 to 1 N is taken. It is place in a solution of hydrochloric acid having strength of one percent and it is keep there for seven days. The solution is agitate at intervals. A good building stones
