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 .

Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Those particles that are predominantly retained on the 4.75 mm (No. 4) sieve, are called coarse aggregates. Those particles passing the 9.5 mm (3/8 inch)

Fineness Modulus of Aggregates: The Inside Scoop - Gilson Co.

An example provided in the ACI 211 standard states that, "For a fine aggregate having a fineness modulus of 2.8 and a 37.5mm nominal maximum size of coarse aggregate, the table indicates that 0.71m3 of coarse aggregate, on a dry-rodded basis, may be used in each cubic meter of concrete. The required dry mass is, therefore, 0.71 x 1600 = 1,136kg."

Specification of Coarse Aggregate | Coarse Aggregate - Raw .

1. The coarse aggregate is clean, hard, non porous, free from lumps of clay and vegetable matter. 2. Water absorption of aggregate is not more than 10 % of its weight after 24 hours immersion in water. 3. Angular and roughly cubicle particles are ideal. River gravels make the best coarse aggregate. 4. Aggregate is chemically inert material. 5.

Aggregate Exposure Levels | Custom Concrete Prep and Polish

T here's a time-honored adage about concrete which states that concrete is consistently inconsistent. Every single pour will be different from the next, with variations in color, cracking and overall flatness. While the polish finish is the end-game for custom concrete applications, aggregate exposure in custom concrete flooring can add a dimension of beauty and interest to the finished product.

Effects of Aggregate Properties on Concrete - Size, Grading

Effects of aggregate properties on Concrete like Grading of aggregates depends on the proportions of coarse and fine aggregate. If grading of aggregate is varied, it also changes cement paste content (cost economy), workability of the mix, density and porosity. It is an important factor and has a maximum influence on workability.
