Aggregates are the major constituent (ingredient) in concrete, making up 60% to 70% of the volume of concrete. Aggregates influence the workability of plastic concrete and also the durability, strength, thermal properties, and density of hardened concrete. Particle size divides aggregates into two categories: fine and coarse. Most fine aggregates are sand and contain …

aggregates cannot be overemphasized. The fine and coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influ-ence the concrete's freshly mixed and hardened proper-ties, mixture proportions, and economy. Fine aggregates (Fig. 5-1) generally consist of natural sand or crushed
Engineering Properties of Aggregates. Aggregates are used in concrete to provide economy in the cost of concrete. Aggregates act as filler only. These do not react with cement and water. But there are properties or characteristics of aggregate which influence the properties of resulting concrete mix. These are as follow. Composition; Size & Shape

These effect of aggregate properties on concrete are discussed in detail. Concrete is a mixture of cementitious material, aggregate and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80% of the volume and 70 to 85% of the weight of the concrete.
When pouring exposed aggregate concrete, a contractor removes the top layer with a chemical inhibitor, water washing, or etching. Exposed aggregate concrete is also called decorative concrete or pebble finish. How is Exposed Aggregate Concrete Made? There are two main ways to create exposed aggregate concrete: mixing and seeding or topping.
