Different Types Sizes of Aggregate for Concrete ...

11/08/2018  Fine Aggregates are usually sand or crushed stone that are less than 9.55mm in diameter. When the aggregate is sieved through 4.75mm sieve, the aggregate passed through it. Natural sand is generally used as fine aggregate, silt, stone dust and clay also come under this category. The purpose of the fine aggregate is to fill the voids in the coarse aggregate and to

Aggregates for Concrete - GreenSpec

- 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. • Larger aggregate diameters reduce the quantity of cement and water needed. 20 mm aggregate . Common aggregates • Crushed Stone and

The effect of fine crushed concrete aggregate on the ...

The specification of crushed concrete aggregates (CCA) is increasing, particularly for low-grade applications, where quality is of less importance. In higher value applications, such as structural concrete, further research is required to understand the effect of CCAs on mechanical and durability performance. One disadvantage of using CCA is that the fine material (0-4mm) is

Aggregate in Concrete - The Concrete Network

If there is a deficiency in a locally available fine aggregate, concrete may benefit from the addition of air entrainment, additional cement, or a supplemental cementitious material (SCM) to address these shortcomings. Broad coarse-aggregate gradation ranges are listed in Table 2 of ASTM C 33. These broad gradation bands are for use all across the country. Once a gradation
