 · Coarse aggregates used in road construction should have the following properties: a.Strength: The aggregate to be used in road construction should be sufficiently strong to withstand crushing and several stresses due to traffic wheel load.

Impact of Multiple Recycling on the Strength of Coarse

Impact of Multiple Recycling on the Strength of Coarse

Strength of aggregate is evaluated in laboratory by Aggregate Crushing Value (ACV) test and Aggregate Impact Value (AIV) test after each generation of recycling. The ACV and AIV values of 1st .

Influence of Crushed Coarse Aggregates on Properties of

Influence of Crushed Coarse Aggregates on Properties of

Both coarse aggregates and fine aggregates are the main constituents of concrete because they not only give the body to the concrete, it also have a significant effect on the fresh concrete based on aggregate’s shape, size, texture, grading and crushing type. Moreover it is proved that aggregate’s types has the severe effect on physic-mechanical properties of concrete as aggregate covered .

Effects of the Parent Concrete Properties and Crushing

 · The present paper reports on the findings of an experimental study on the concomitant effects of the strength of the parent concrete, size of the natural aggregates used in the parent concrete, and the number of crushing stages on the properties of coarse recycled concrete aggregates, including mortar content, water absorption, bulk density .

How to Determine the Aggregate Crushing Strength Value

How to Determine the Aggregate Crushing Strength Value

 · Procedure for crushing strength of aggregate. Before testing, the aggregate should be in surface dry condition.You can achieve the dry condition of aggregate by placing aggregates in an oven for 4 hours at 100-degree Celcius. The aggregates passing through 12.5mm and retained on 10mm IS sieves are selected for finding aggregate crushing strength.
