CHAPTER 1—INTRODUCTION. Hydraulic cement concrete is a cement and water paste in which aggregate particles are embedded. Aggregate is granular material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete.
However, a further increase in aggregate sizes to 40 mm resulted in a decrease in the slump response to 40 mm. Additionally, in the case of laterized concrete, the slump results tended to decrease ...
Aggregates are intensively used in civil and transportation infrastructures.

Aggregate Crushing Value (ACV) This test is used to find the strength of the coarse aggregate and indicates the resistance to crushing under a gradually applied crushing load. It is measured as the percentage of aggregates passing through 2.36 mm IS sieve after the specimen subjected to a compressive load of 40 tonnes at the rate of 4 …

Sampling of Aggregates. Select coarse aggregate that passes through a 12.5mm IS sieve and is retained on a 10mm IS sieve. Heat the aggregate at 100 to 110°C for 4 hours, cool it to room temperature, and ensure that the material depth in the cylinder, after tamping as described below, is 10 cm. Determine the appropriate quantity by filling …
Aggregate Crushing Value = 100(W2/W1) percent where: W2 = Weight of fraction passing the appropriate 2.36 mm sieve. W1 = Weight of dry sample. Normally, the percentage of fines should fall between 7.5 and 12.5. If it falls outside this range, conduct a new test at a load adjusted to bring the percentage of fines within the range of 7.5 to 12.5.
Aggregate crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve W1-W =Weight of surface dry sample. The mean of two result to nearest whole number is the …
