Aggregates are one of the most important constituents of the concrete which give body to the concrete and also reduce shrinkage. Aggregates occupy 60 to 80 % of total volume of concrete. So, we can say that one should know definitely about the aggregates in depth to study more about concrete. Aggregate may be natural, manufactured or recycled.

Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate. When determining the strength of normal concrete, most concrete aggregates are several times,Importance of Aggregate Gradation of concrete slab,For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause deterioration of concrete. Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categories–fine and coarse. Fine aggregates generally consist of natural sand or crushed,Sieve Analysis of Fine Aggregates || Procedure and Test,,The Aggregates(fine + coarse) generally occupy 60% to 75% of the concrete volume or 70% to 85% by mass and strongly influence the concrete’s freshly mixed and hardened properties, mixture proportions, and economy.

This specification covers the quality and grading of fine aggregate for hydraulic cement concrete used in pavements or bases highway bridges and incidental structur This specification is for use by a contractor concrete supplier or other purchaser as part of the purchase document describing the material to be furnished . Gradation of Coarse Aggregates. Proper gradation of coarse aggregates is,Types of Aggregates: Classifcation based on Unit Weight,,One-fifth of the minimum dimension of reinforced concrete cement. Shape: The shape of the aggregate types affects the work ability of the concrete and its strength. These are in four types-1. Rounded: It has 33-35% voids, it is not suitable for concrete. 2. Irregular or partly rounded: it has 35-37% voids, it useful for medium quality concrete. 3.Construction aggregate - Wikipedia,Construction aggregate, or simply aggregate, is a broad category of coarse- to medium-grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates.Aggregates are the most mined materials in the world.

Those particles that are predominantly retained on the 4.75 mm (No. 4) sieve, are called coarse aggregates. Those particles passing the 9.5 mm (3/8 inch)(PDF) REPLACEMENT OF FINE AGGREGATE WITH,Concrete mixes with different chemical admixtures dosages of 0.2%, 0.4%, 0.5%, and 1.0% of cement were prepared. Standard cubes of 100mm*100mm*100mm were casted. After casting, normal curing was,Sieve Analysis of Coarse and Fine Aggregates,Larger value of FM is preferred for fine aggregates. For a good fine aggregate, the FM should be between 2.3 and 3.1 (ASTM Range for fine aggregates). A FM of 4 can be interpreted to means that the fourth sieve from bottom i.e. sieve No. 16 is the average size of the aggregate particles in the given sample. Limitations of Sieve Analysis:,,,,
