Aggregate crushing value is an indicator of the crushing resistance of the aggregates when a compressive load is increased. It is tested in accordance with BS 812:110, 1990 and aggregate passing a 14mm test sieve and retained on 10mm sieve are considered for the testing. The allowable range is 17- 41. TESTING OF FLAKINESS INDEX
Aggregate used in construction are tested for the following parameters, The aggregates are tested to determine their properties like, Strength Toughness Hardness Shape Water Absorption etc. A good coarse aggregate should possess the following characteristic, It should be angular or cubical in shape. It must be sound & durable.

The water absorption test determines the durability of concrete. The three cube samples shall be taken from the tank for 28 days 24 hours the concrete sample would be demoulded and it will be sent directly to the approved third-party laboratory to ensure its curing. The size of the cube sample is 150 mm. Initial surface Absorption test
They can be used in many ways: as major components of concrete, mortar or bituminous bound materials, as sub-base or capping or for more specialised uses such as track ballast or filter …

Aggregate gradation is of 4 types as explained below: 1.Well-Graded: An aggregate sample is said to be well-graded if it possesses all the required sizes in the required proportions. In other words, such a sample has a wide range of particle sizes present in the mix. Fig. 1: Well-graded Aggregate Sample 2.Gap-Graded:

CONCRETE CYLINDER TESTING Test cylinders ( ASTM C 31) are cast to verify the specified compressive strength of the mix has been achieved. Typically 6-inch-diameter by 12-inch-tall plastic molds are used. Some projects use 4-inch-diameter by 8-inch-high cylinders. Fill the 6-inch-diameter molds in three equal layers, rodding each layer 25 times.

All aggregate used for construction purposes must be tested, physically and chemically, to verify its suitability for these uses. Every potential production site must be tested to ensure that the materials meet specifications for a particular application and to determine processing requirements.
The experiment aims to test the specific way of producing concrete with recycled concrete aggregate (RCA). To reduce its negative impact on the concrete properties, two different ways of treatment of the RCA with geopolymer slurry were applied—coating during the mixing using the specific mixing approach and coating prior to the mixing of concrete. As …

Gilson aggregate testing equipment measures and evaluates the physical characteristics of fine and coarse aggregates for asphalt and concrete mixes. Size, shape, density, and strength of mineral aggregate all impact the long-term performance of …
In most concrete, aggregates are more or less chemically inert. However, some aggregates react with the alkali hydroxides in concrete, causing expansion and cracking over a period of many years. This alkali-aggregate reaction has two forms: alkali-silica reaction (ASR) and alkali-carbonate reaction (ACR).
The aggregate crushing value test result should not be more than 30 % for the concrete used for roads and pavements and, in case of other structures; it may be permitted up to 45%. (c) Standard Guidelines for Crushing Test: Followings are the standard guidelines for the crushing test on aggregates:
