Concrete Mix Proportions and Measurements
Project specifications for concrete can generally be divided into two classes: prescription specifications and performance specifications, with some including features of both.

Typical of the prescription type is the outmoded volume-proportion requirement such as 1:2:3, meaning one part cement, two parts sand, and three parts aggregate by volume with water only being limited by the maximum amount of slump allowed.

High-strength and watertight, general use, and foundations are the most common types of concrete. Each type is used for different purposes.

Click on each type of concrete mix ratio to know more:
High-Strength
• Cement = 1 part
• Sand = 2 parts
• Stone or gravel = 3 parts
This concrete mix ratio will give you high-strength concrete plus watertight properties making it great for ponds, and structural uses such as concrete panels and building slabs.

General Use
• Cement = 1 part
• Sand = 2.5 parts
• Stone or gravel = 3 parts
This concrete mix ratio will give you concrete that is great for paths, floors, general landscaping, and driveways.

Mortar
Mortar is a mix of sand, cement, lime, and water. When mixed properly, it forms a bond between masonry surfaces such as bricks and concrete blocks of all different sizes.

• Cement (using general purpose cement) = 1 part
• Sand = 6 parts
• Lime = 1 part
Foundations and Large Volume

• Cement = 1 part
• Sand = 3 parts
• Stone or gravel = 5 parts
Foundations, where a large amount of concrete is used to fill up strip footings trenches, are the main use for this concrete mix ratio. It is also used in house foundations, to make them solid and stable, when filling from bedrock to ground level.
