The aggregate shall be taken as in the case of crushing strength value test i.e., the aggregate should pass through 12.5 mm I.S. sieve and retained on 10 mm I.S. sieve. It should be oven dried at 100°C to 110°C for four hours and then air cooled before test.

Jul 31, 2016· Locally available crushed igneous rocks from Pakur with 16 mm graded size have been used as coarse aggregate. The physical properties for the coarse aggregate as found through laboratory test are as follows: Aggregate crushing value = 24%. Aggregate impact value = 29%. Specific gravity = 2.713. Water absorption = 0.755.

The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third 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. Now fill the aggregate in the mould along with the plunger on top.

Oct 14, 2020· Aggregate Crushing Value Test.

Apr 20, 2018· The main factor affecting specific gravity, water absorption and bulk density of RA is the old mortars adhering to it. A lower percentage of aggregate crushing value indicates tougher and stronger aggregates. From the results, it is observed that the crushing value of NA and RA is 14.2 and 17.69% respectively.

There is no specification for bulk specific gravity, but it is used to calculate other specified parameters such as air voids, VMA and VFA. Typical Values. Typical values for bulk specific gravity range from 2.200 to 2.500 depending upon the bulk specific gravity of the aggregate, the asphalt binder content, and the amount of compaction.

Feb 08, 2012· Toachieve a high quality of pavement, aggregate possessing low aggregate crushing value should be preferred.Apparatus The apparatus for the standard aggregate crushing test consists of the following: (i) Steel cylinder with open ends, and internal diameter 25.2 cm, square base plate plunger having a piston of diameter ~ with a hole provided ...

The Fine Aggregate Test (ASTM C128 and AASHTO T 84) is a comparison of sample masses in oven-dry, saturated surface-dry (SSD), and immersed conditions. This test method offers alternate procedures to determine specific gravity. Either a volumetric flask or a simple pycnometer can be used for the gravimetric procedure. For the volumetric procedure, a special Le Chatelier flask is needed.

May 14, 2015· This paper discusses the suitability of producing concrete with 100 % recycled aggregate to meet durability and strength requirements for different applications. Aggregate strength, gradation, absorption, specific gravity, shape and texture are some of the physical and mechanical characteristics that contribute to the strength and durability of concrete.

Calculate Aggregate Crushing Value. The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place: Aggregate Crushing Value = W B W A × 100. Where, W A is weight of surface-dry sample

AGGREGATE CRUSHING VALUE 1.Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead.
