· Aggregates Testing. Aggregates make up the largest volume (66% to 78%) of material used in concrete. The aggregates must be clean, properly graded, hard, strong, durable, and free from chemicals or coatings of clay or other foreign materials that may inhibit the bond between the cement and aggregate. Testing must be performed to make sure that ...
· Specific gravity and Water Absorption Test of Aggregates are major important tests to be performed on aggregate. These two parameters or properties of aggregate play an important role in the mix design of concrete. As we know that aggregate occupies 70 to 80% volume of concrete, its testing becomes essential before use.

Alkali-Aggregate Reaction. In most concrete, aggregates are more or less chemically inert. However, some aggregates react with the alkali hydroxides in concrete, causing expansion and cracking over a period of many years. This alkali-aggregate reaction has two forms: alkali-silica reaction (ASR) and alkali-carbonate reaction (ACR).
