May 29, 2011· Fine Aggregate vs Coarse Aggregate The words fine and coarse aggregate are used in conjunction with materials that are used to mix with concrete in construction activities. Aggregate is a composite material that helps in binding the concrete together as it adds strength and reinforcement to concrete.
Aggregates can be classified in many ways. Classification of aggregates based on shape and size such as coarse and fine aggregates are discussed here, Aggregates are the important constituents of the concrete which give body to the concrete and also reduce shrinkage. Aggregates …
Examples of natural aggregates include sand, gravel, limestone, sandstone,igneous rock and others. Sand is one example of a natural aggregate. It’s a natural granular material consisting of fine mineral and rock fragments and is mixed with cement to make concrete. Gravel is another type of a natural aggregate.
But mainly it consists of coarse sizes. A coarse aggregate of uniform size known as macadam, received its name from a Scottish engineer John Macadam. He first used it in asphalt mix. Fine graded. Those which passes through sieve # 4 and retain on sieve # 200 are the fine aggregates. Fine graded have a predominance of fine sizes. Filler
Jul 07, 2014· Crushed Gravel Sand– it is the fine aggregate produced by crushing natural gravel. According to size the fine aggregate may be described as coarse sand, medium sand and fine sand. IS specifications classify the fine aggregate into four types according to its grading as fine aggregate of grading Zone-1 to grading Zone-4.
Aggregate is classified as two different types, coarse and fine. 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.
Construction aggregate is a broad category of granular raw material of different sizes (sand, gravel, crushed stone, slag, recycled concrete etc) used in construction. Uses of aggregate in civil engineering include the following: Also See: Types of Aggregates. Uses of Aggregates. Aggregate can be used in a number of ways in construction.
You can find many types of aggregates — they’re the most commonly mined minerals in the world. Examples of the materials we produce and distribute include: 2A stone: Also known as 2A crushed stone or 2A modified stone, this material is a mixture of crushed stone and coarse stone dust and derives its name from its 2-inch top size.

FINE AGGREGATE. “Fine aggregate” is defined as material that will pass a No. 4 sieve and will, for the most part, be retained on a No. 200 sieve. For increased workability and for economy as reflected by use of less cement, the fine aggregate should have a rounded shape.
Aggregate Classification | Types of Aggregates. Aggregates are variously classified on the basis of their grain size, their origin, and their volume-weight as follows: (1.) Aggregate Types on the basis of Grain Size. This is the most common classification, where in two types of aggregates are distinguished: (Fine and Coarse). (i) Fine Aggregates.
Apr 14, 2017· It is the aggregate most of which passes through a 4.75mm IS sieve and contains only that much coarser materials as it is permitted by the specifications. Sand is generally considered to have a lower size limit of about 0.07mm. The fine aggregate may be one of the following types:

Here I am going to write about the types of aggregates based on nature or origin, that is natural aggregate and artificial aggregate.
Grading of Aggregates. Grading of aggregates is determining the average grain size of the aggregates before they are used in construction. This is applied to both coarse and fine aggregates.The aggregate sample is sieved through a set of sieves and weights retained …
Aug 11, 2018· When the aggregate is sieved through 4.75mm sieve, the aggregate passed through it. Natural sand is generally used as fine aggregate, silt, stone dust and clay also come under this category. The purpose of the fine aggregate is to fill the voids in the coarse aggregate …
Types of aggregates include Coarse aggregate and fine aggregate. The aggregate of each type is further sub-divided into many types and classification based on its size. The technique of Sieve Analysis is used for gradation of aggregate for use in concrete and for other applications.
