Test Procedure. The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with onethird of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1.
Ultrasonic Pulse Velocity Test Procedure. During the test, the transducer held in contact with one surface of concrete and it traverse a known path length Q in the concrete and then an electrical signal passed the second transducer held in contact with the other surface of the concrete member and the transit time (T) of the pulse to be measured.

· Apparatus for Crushing Test. The apparatus for the standard aggregate crushing test as per IS: (Part IV) consist of the following: The test molda cm diameter openended steel cylinder with square base plate; plunger having a piston of diameter 15 cm, a rod could be inserted for lifting or placing the plunger in the cylinder with a provided hole across the stem of the plunger. A ...
· Aggregate crushing value and its test procedure one of the test in which concrete material can fail is due to crushing under compressive stress aggregate crushing test is standardized by is 2386 partiv and used to verify the crushing strength of aggregates the aggregates should be oven dried which can passes through 125mm and retained on . Aggregate Crushing Value Test. .
Procedure of Slump Test. If the test is being conducted on the ground, a sample of the concrete mix must be acquired for the test. Wet sieving is required for concrete that contains aggregates with a maximum size of 38mm (millimetres) or larger.
Apparatus Required. 1. A ventilated oven. 2. A weighing balance with a sensitivity of less than %. 3. Sample of whole bricks . Procedure. The procedure for the absorption test on bricks includes the following series of steps: i. The brick specimen is first dried in the ventilated oven at a temperature ranging from 105 degrees Celsius to 115 ...
Concrete test cube manufacturing and curing procedures. The strength of concrete is generally measured by testing concrete cubes which are prepared from the concrete used in that particular construction. The cube strength of concrete is specifi ed by a structural engineer and is assessed by crushing concrete cubes at a specifi ed age (28 days ...
Aggregate Crushing value is a relative resistance of aggregates to crushing under gradually applied compressive load. Aggregate Crushing Value Test is important to test to be performed on aggregate. The strength of aggregate parent rock is determined by preparing cylindrical shape specimens of size 25 mm diameter and 25 mm height.
As per IS Code, the sample selection for the concrete cube test has listed below. The minimum value of Compressive Strength for a cube. As per IS 456, the individual compressive value of a concrete cube should not be less than 75% of its grade. Example – If the concrete grade is M20, then the individual crushing value should not be less than ...

the concrete crushing test procedure and its apparatus. Aggregates crushing value test compression testing,they give body of the concrete, reduce shrinkage and effect economy. earlier researchers consider aggregate as an inert material but now its not the case. aggregates can also have chemically active materials in it. test for determination of aggregate crushing value apparatus for ...
METHOD OF MAKING AND CURING CONCRETE TEST SPECIMENS IN THE FIELD FOP FOR AASHTO T 23 Scope This procedure covers the method for making, initially curing, and transporting concrete test specimens in the field in accordance with AASHTO T 2308. Warning—Fresh Hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged .
Test Procedure. The cylinder of the test apparatus shall be put in position on the baseplate and the test sample added in thirds, each third being subjected to 25 strokes from the tamping rod. The surface of the aggregate shall be carefully levelled and the plunger inserted so that it rests horizontally on this surface, care being taken to ...
