What are the tests for aggregates?
In order to decide the suitability of the aggregate for use in pavement construction, following tests are carried out:
- Crushing test.
- Abrasion test.
- Impact test.
- Soundness test.
- Shape test.
- Specific gravity and water absorption test.
- Bitumen adhesion test.
How do you determine aggregate quality?

What is aggregate impact test?
Theory of Aggregate Impact Test This characteristic is measured by impact value test. The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load.
Which test is carried out to test the durability of aggregates?

Is water bad for concrete?
Water is an essential component when making concrete. The moisture that water provides also gives concrete its strength during the curing process. While water is one of the most important ingredients in concrete, it can also be the most destructive in excessive amounts.
Why is too much water bad for concrete?
Over-watered concrete may lead to lower strength, reduced durability, shrinkage cracking, and a variety of surface problems. It is critical that the proper amount of water be added to concrete and other cement mixes.
Does all concrete crack?
Dear James: Unfortunately, cracking is pretty common in concrete, especially during the first 30 days, while it's curing or setting up.
