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 ...

Sieve Analysis Test Procedure and Calculation. The aggregates are graded as fine and coarse aggregate based on the grain size. When the aggregate size is greater than 4.75mm is called coarse aggregate, and less than 4.75mm is called fine aggregate. The sieve analysis test will do the grading of aggregates. Contents of the Article show.

Aggregate Water Absorption Test. Water absorption gives an idea of strength of aggregate. Aggregates having more water absorption are more porous in nature and are generally considered unsuitable unless they are found to be acceptable based on strength, impact and hardness tests. Water absorption shall not be more than 2% per unit by weight.
