This test is crucial in concrete technology as it indicates the strength and quality of aggregates, which directly influence the durability and performance of concrete structures.
Aggregate Crushing Strength Test
The crushing strength or aggregate crushing value of a given road aggregate is found out as per IS-2386 Part- 4. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement aggregate possessing low aggregate crushing value should be …

Technical Manual – Section 1 Introduction to
Fire Resistance – Lytag® lightweight aggregate has a Class 1 fire resistance because the aggregate has been produced by a refractory process. In addition, the cellular structure of the aggregate particles relieves any pressures from expanding gases. The result is a material that is highly stable at elevated temperatures.
Ten per cent fines value (TFV) — Material Testing Expert
— 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.
