Detailed introduction
Grading of Fine Aggregate
The grading of fine aggregate has a significant effect on the workability of the concrete mix. The Fineness Modulus is used in US practice and is a measure of the grading of fine aggregates. It can be calculated from a sieve analysis by adding the cumulative percentages of fine aggregates retained on the following sieve sizes; 0.15mm, 0.30mm, 0.60mm, 1.18mm, 2.36mm and 4.75m. Get price

The requirements of AS 2758.1
Concrete is a construction material made of a mixture of glue (cement, fly ash, GGBF-slag, etc), rocks (coarse aggregate), sand (fine aggregate) and water that hardens to a stone-like mass. Chemical admixtures are frequently used to accelerate or retard set time Get price
Aggregate Properties
A majority of the volume of concrete (60 – 80%) is occupied by aggregate. In fact, for most conventional concretes, more than 75% of the volume is aggregate. Aggregates are essential in concrete from the point of view of economy (since cement is expensive), dimensional stability (aggregates do not easily creep or shrink), stiffness, and abrasion resistance.

Suitability of Scoria as Fine Aggregate and Its Effect on the Properties of Concrete
Fine aggregate is one of the ingredients of concrete that needs to get considerable attention in the production of green concrete, and it usually comprises up to 30% to 35% of the total volume of concrete. Natural or river sand is the most commonly used fine Get price
Aggregate Sizing Explained
Aggregate serves as a reinforcement to add strength to composite materials such as concrete. Aggregates can be categorized into three groups: fine aggregate, coarse aggregate, or all-in aggregate. Fine aggregate, such as concrete or masonry sand is defined as material that mostly passes through a 4.75 mm IS sieve. Get price
