Interpret the grading curve for shotcrete

Screening test to separate the aggregate particles . The process to obtain the grading curve consists in passing the aggregate sample through a series of standardized sieves of different diameters mounted on a column. The aggregates are exposed to vibration and rotation movements in order to obtain the classifiion by size.

Sieve analysis Wikipedia

A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.

Grading refers to the determination of the particlesize distribution for aggregate. Grading limits and maximum aggregate size are specified because these properties affect the amount of aggregate used as well as cement and water requirements, workability, pumpability, and durability of concrete.

Fine aggregates are essentially any natural sand particles won from the land through the mining process. Fine aggregates consist of natural sand or any crushed stone particles that are ¼" or smaller. This product is often referred to as 1/4'" minus as it refers to the size, or grading, of this particular aggregate. Fine aggregates are

between the terms fine aggregate and sand, there is in fact no difference the two words may be interchanged. However, the new European standard uses the term fine aggregate. The historic terminology is just that used by local tradition and custom. Fine aggregate quality is affected by a number of factors: • The mean particle size • The grading

Aggregate Gradation Terms Fine aggregate: (sometimes just referred to as "fines"). Defined by AASHTO M 147 as natural or crushed sand passing the 4.75mm and mineral particles passing the 75um sieve. Coarse aggregate: Defined by AASHTO M 147 as hard, durable particles or fragments of stone, gravel or slag retained on the 4.75mm sieve.
