water ratio is required when making concrete. Fine aggregate are basically sands won from the land or the marine environment. Fine aggregates generally consist of natural sand or crushed stone with most particles passing through a 9.5mm sieve. For concrete sand fineness modulus range is 2.3-3.1.
A typical concrete mix cannot be made without gravel. Concrete is made from a mixture of cement, sand, gravel (crushed stone), and water. A mix ratio of 1 part cement, 2 parts sand, 3 parts gravel, and water, will give you a strong concrete mix. If you subtract the gravel from concrete, you have what's called a mortar mix.

Lime is also a common additive to the mix.
The quality of the sand is as important as other materials for concrete. The most different, which passes through the 4.75 mm IS strainer, is known as the fine aggregate. The fine aggregate will typically consist of natural sand, crushed stone sand, crushed gravel sand stone dust or arable powder, fly ash, and broken brick (burnt clay).
Jan 30, 2014· The closer you bring the ratio to an even one-to-one of sand to cement, the stronger the rating becomes. This principles works in the opposite direction as well. If you want to get a little more technical, some concrete experts recommend going for 26 percent sand, 41 percent gravel, 11 percent cement and 16 percent water.
