Different Types & Sizes of Aggregate for

2018-8-11  When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate. Gravel, cobble and boulders come under this category. The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete.

Aggregate sizes Concrete

Aggregate sizes. Fine aggregate is material that will pass through a 4mm sieve. Generally fine aggregate is a naturally occurring sand material, crushed rock material, or a combination of both. The distribution of particle sizes, known as grading, is important because it effects some properties of the plastic concrete, e.g. water demand and

1, meet the strength grade of concrete design. 2, meet the concrete peaceability. 3, meet the durability of the use of concrete. 4, meet the above conditions to save cement and reduce the cost of concrete. The strength of concrete is divided into twelve grades, such as C7.5, C10, C15, C20, C25, C30, C35, C40, C45, C50, C55, C60 and so on.
