  • 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.

  • 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

    A gap is where the aggregate mix completely passes through one or more of the sieves within the aggregate range. This is a stricter requirement than ASTM's. For example, ASTM C 33 allows the #467 stone to leave no material retained on the 25.0 mm (1inch) and 12.5mm (0.5inch) sieves.

  • Aggregate in Concrete The Concrete Network

    Fine aggregate should fall within gradation limits provided in ASTM C 33, Section 6. 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.

  • Sieve Analysis of Aggregates Civil Engineering

    Sieve analysis helps to determine the particle size distribution of the coarse and fine aggregates.This is done by sieving the aggregates as per IS: 2386 (Part I) – 1963. In this we use different sieves as standardized by the IS code and then pass aggregates through them and thus collect different sized particles left over different sieves.
