# Concrete Aggregate Crushing Value

### Crushing Value Of Aggregate

The test conducted to know the compressive strength of aggregate is known as aggregates crushing value test. The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason, a simple test known as 10 percent fine value is introduced. When the aggregates crushing value become 30 or higher ...

### Aggregate Crushing Value Test Significance Amp Test

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.

### Aggregate Crushing Value Test Procedure And Result

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 ...

### Aggregate Crushing Value Test Determine Aggregate

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS 2386 Part IV 1963. The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes 12.5mm, 10mm and 2.36mm Procedure to determine Aggregate Crushing Value i The aggregates passing through 12.5mm

### Aggregates For Concrete

Crushing, screening, ... Sieve sizes commonly used for concrete aggregates are detailed in Table 1, and various physical properties of normalweight aggregates, with typical range values, are shown in Table 2. Coarse and fine aggregates are generally sieved separately. That portion of an aggregate passing the 4.75 mm No. 4

### Recycled Concrete Aggregates Its Uses Properties

Aug 18, 2020 The density of recycled concrete aggregate is smaller than natural aggregate density. Impact Value and Crushing Value. The recycled concrete aggregate is relatively weaker than the natural aggregate against mechanical actions. As per IS 2386, the impact and crushing value for concrete wearing surfaces should not exceed 50 and 45 respectively.

### Aggregate Crushing Value Test Step By Step Procedure

It is recommended that the crushing value of aggregate should be less than 30. If it is more 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.
