Name of the experiment Aggregate Crushing value test. Objective 1. Determine the aggregate crushing value of coarse aggregate. 2. Assess suitability of coarse aggregates for use in different types of road. Theory The “aggregate crushing value” give a relative measure of the resistance of an aggregate to crushing under gradually applied.Precautions of determine the crushing value of road aggregates. precautions of determine the crushing value of road aggregates. as a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size reduction requirements including quarry, aggregate, and different kinds of minerals.
DETERMINATION OF AGGREGATE CRUSHING VALUE 1) To determine the aggregate crushing value of coarse aggregates 2) To assess suitability of aggregates for use in different types of road pavement 2 PRINCIPLE The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Crushing value is aAggregate.

Aggregate Crushing Value Test – Determine Aggregate 2019-5-17 Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in road construction is expressed by numerical index.
AGGREGATE CRUSHING VALUE TEST AIM (i) to determine crushing value of given road aggregates (ii) to assess suitability of aggregates for use in different Aggregate Crushing Value AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS 2386 (Part IV) – 1963.
Sep 12, 2015 Crushing Test Fig-1 Crushing Test Setup One of the model in which pavement material can fail is by crushing under compressive stress A test is standardized by IS 2386 part-IV and used to determine the crushing strength of aggregat The aggregate crushing value provides a relative measure of resistance to crushing under gradually.
Crushing Strength Of Aggregates Definition. Sep 12 2015One of the model in which pavement material can fail is by crushing under pressive stress A test is standardied by IS 2386 partIV and used to determine the crushing strength of aggregates The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing.
5 Then the entire aggregate sample in a measuring . Concrete Lab Manual Dept. of Civil Engg., SJCE, Mysuru Page 37 AGGREGATE CRUSHING VALUE TEST Exp. No. 15 AIM To determine the crushing value of the road aggregates APPARATUS The apparatus of the aggregate crushing value test as per IS 2386 (Part IV) – 1963consists of A 15cm diameter open ended steel cylinder with.
Aggregate Crushing Value Test – Determine Aggregate Crushing . The apparatus for the standard aggregate crushing test as per IS 2386-1963 (Part IV) consist of the following The test mold-a 15.2 cm diameter open-ended 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.
It is recommended that the crushing value of aggregate should be less than 30 . If it is than 30 then 10 finer aggregate is suggested to use. The aggregate whose crushing value is less than 30 can be used for cement concrete road. The aggregate whose crushing value is less than 40 can be used for wearing surface.
The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines value” should be determined.
Aug 27, 2019 The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load. It is expressed as the percentage by mass of the crushed (or finer) material obtained when the test sample is subjected to a specified load under standard conditions. Aggregates with lower crushing value.
Mar 29, 2021 Aggregate Crushing test (IS 2386(Part 4) 1963 BS 812–110 1990) Aggregate crushing test values indicates the strength of aggregate and hence it is very significant. Similarly we can say crushing value is the relative measure of resistance of an aggregate under gradually applied compressive loads.
An aggregate to crushing under the applied compressive load. In other word is a value which indicates the ability of an aggregate to resist crushing. It is used to determine the crushing value of a given road aggregate also it is used to assess the suitability of aggregate for use in different road pavement.
