Aggregate Crushing Value Test Procedure, Result
Aggregate Crushing Value is the relative resistance of aggregates to crushing under gradually applied compressive load. The aggregate Crushing Value Test is an important test to be performed on aggregate. Aggregate crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve W1-W =Weight of surface dry Aggregate Crushing Value Test The Constructor

Aggregate crushing value test Step by Step
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 Crushing is one of the most energy-consuming technological processes. The purpose of grinding is to achieve the desired grain size of mineral raw materials. The process of grinding consists of many factors, for example, the size and form of crushed grains, as well as their mutual arrangement inside the crushing machine chamber, the Influence of Natural Aggregate Crushing Process on Crushing

Aggregate Crushing Value (ACV) is an index of loss of coarse aggregate (CA) under sustained loading. However, ACV is not considered in concrete mix design according to ACI 211.1(ACI 211.1, 2009). In this paper effect of ACV of CA on compressive strength of concrete has been explored. Coarse Aggregate was collected from five different Calculate the aggregate crushing value (ACV) expressed as a percentage to the first decimal place, of the mass of fines formed to the total mass of the test specimen from the following equation; M2 is the mass of the crushed material passing the 2.36 mm test sieve (in g) M3 is the mass of the crushed material retained the 2.36 mm test sieve (in g)Aggregate Crushing Value (ACV) Test Procedure, Calculations
