Fine-Aggregate Grading. Grading Requirements of ASTM C 33 or AASHTO M 6/M 43 permit a relatively wide range in fine-aggregate gradation, but specifications by other organizations are sometimes more restrictive. The most desirable fine-aggregate grading depends on the type of work, the richness of the mixture, and the maximum size of coarse ...

Understanding Coarse Vs. Fine Aggregates - .Deze pagina vertalen

Fine Aggregate. You can expect fine aggregate to easily move through a 4.75 mm sieve but retain when the sieve is just .075 mm. So, the fine pieces are smaller, consisting of sand, burnt clay, cinders, and fly ash. The main role of the fine aggregate is to fill in the space that is created between pieces of coarse aggregate.

mixture with excessive fine material can be sticky and difficult to finish. For example, ACI 211.1, Table 6.3.6, recommends that if fine aggregates have a high proportion of fine material (manifested by a low fineness modulus), then the amount of coarse aggregate should be increased, thereby indirectly decreasing the quantity of fine aggregate

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)

How Coarse Aggregate Affects Mix Design of .Deze pagina vertalen

Coarse aggregate is one of the essential components of concrete and occupies the largest volume in the mix. That is why it greatly affects the concrete mix design. Its properties such as strength, maximum size, shape, and water absorption influence water demand, the quantity of cement and fine aggregate in concrete mixture. It is reported [.]
