How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine small and coarse larger aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
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.

Mar 11, 2020 The production of aggregate for the infrastructural development of the country has been increasing for the last three decades due to the high urbanization rates in the main cities of the country and the ever-growing demand for basic infrastructural facilities. The environmental impact of both fine and coarse aggregate production is now hard to ignore especially on the outskirts of the main cities.
Fine aggregate Coarse aggregate Fine Aggregate When the aggregate is sieved through a 4.75mm sieve, the aggregate passed through it called fine aggregate. Natural sand is generally used as fine aggregate, silt and clay also come under this category. The soft deposit consisting of sand, silt, and clay is termed as loam.
Nov 21, 2020 Alternative materials for coarse aggregate in concrete can be rubber, glass, expanded fly ash clay, or plastic materials. On the other hand, agro-wastes, to industrial by-products, alternative materials for fine aggregate in concrete can be of a wide variety. In the following section, you will get a brief idea on these aggregate alternatives.
Aggregates are divided into either coarse or fine categories. - Coarse aggregates are particulates that are greater than 4.75mm. The usual range employed is between 9.5mm and 37.5mm in diameter. - Fine aggregates are usually sand or crushed stone that are less than 9.55mm in diameter.
