What are the types of sands?
We shall now look at the various types of sand used in the construction:
- River Sand. This kind of sand is usually found near river banks and streams.
- Concrete Sand. It is a type of sand made from crushed concrete with a mixture of asphalt and cement.
- Fill Sand.
- Coarse Sand.
- Utility Sand.
- Pit Sand.
- Fine Sand.
- M-Sand.
What kind of sand do you mix with cement?
coarse sand
It is used in concrete and can also be used for rendering walls and floors. The best sand to use for rendering is coarse sand, which can give a smooth finish appropriate for most vernacular buildings. This type of sand holds even when the mix is a little richer in lime than a standard pointing mix.
What size of sand is used in concrete?
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. Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete.
What are the 4 types of sand?

What are different types of sand used for?
The main types of sand used in construction range from concrete sand to pit sand, natural or river sand, manufactured sand (M-sand), utility sand, and fill sand. These types of sands have unique properties that make them ideal for various types of construction.
Can you use any sand for concrete?
Coarse sand should only be used for concreting jobs and soft sand should only be used for render or mortar. Coarse aggregate generally lies between a 4mm and a 20mm sieve and is typically nearly half the weight of the concrete.

What is Zone 4 sand?
Generally, manufactured sand is classified as Zone I, Zone II, Zone III and Zone IV (i.e. coarser to finer). There is sieve designation for each zone.
Is Zone 3 sand good for concrete?
It is generally recommended by code to use sands of zones I to Zone III for Structural concrete works.
Can I use soft sand in concrete?
Building or soft sand should not be used in concrete, as the grading is finer than concreting fine aggregate and leads to increased water demand. It is usually used for mortars and renders.
Is sharp sand used for concrete?
Sharp sand, also known as grit sand or river sand and as builders’ sand when medium or coarse grain, is a gritty sand used in concrete and potting soil mixes or to loosen clay soil as well as for building projects.
