What Is a Flakiness Sieve Set?<\/h2>\n

The Flakiness Sieve Set<\/strong> is used to determine the particle shape of coarse aggregates by measuring their flakiness index<\/strong>. The test identifies particles with relatively small thickness compared with their other dimensions.<\/p>\n

The aggregate sample is first separated into specified size fractions. Each fraction is then tested using the appropriate bar sieve opening.<\/p>\n

Particles that pass through the parallel bars are classified as flaky particles for the relevant fraction.<\/p>\n

Flakiness Index Determination<\/h2>\n

The test is based on the thickness of individual aggregate particles.<\/p>\n

After preliminary sieving, the operator places each aggregate fraction onto the corresponding Flakiness Bar Sieve<\/strong>. Thin particles pass through the slot between the bars, while thicker particles remain above the sieve.<\/p>\n

The mass of the material passing through the bar sieves is then determined and compared with the total dry mass of the test sample.<\/p>\n

This procedure allows the laboratory to calculate the overall flakiness index.<\/p>\n

14 Different Aperture Sizes<\/h2>\n

Liya Test offers 14 individual bar sieve sizes<\/strong> ranging from 2.5 mm to 50 mm<\/strong>.<\/p>\n

Available aperture sizes are:<\/p>\n

2.5, 3.15, 4, 5, 6.3, 8, 10, 12.5, 16, 20, 25, 31.5, 40 and 50 mm.<\/strong><\/p>\n

This wide range allows different aggregate fractions to be evaluated using the appropriate aperture.<\/p>\n

The LT-A0012\/S Complete Set<\/strong> combines all individual Flakiness Bar Sieves into one laboratory set.<\/p>\n

Stainless Steel Bar Construction<\/h2>\n

Each sieve incorporates parallel stainless steel bars<\/strong> arranged to form the specified opening.<\/p>\n

The bars are approximately 5 mm in diameter<\/strong> and are mounted inside a rigid metal frame.<\/p>\n

The rigid construction helps maintain the geometry of the openings during repeated laboratory use.<\/p>\n

The external metal structure is also protected with a powder-coated finish to support resistance against corrosion.<\/p>\n

Aggregate Quality Control<\/h2>\n

Particle shape can influence the behaviour of aggregates during mixing, compaction and placement.<\/p>\n

Flat particles may behave differently from more cubical particles and may also be more susceptible to breakage during handling or loading.<\/p>\n

For this reason, flakiness index testing is widely used in:<\/p>\n

    \n
  • aggregate laboratories<\/li>\n
  • asphalt laboratories<\/li>\n
  • ready-mixed concrete laboratories<\/li>\n
  • quarries<\/li>\n
  • road material laboratories<\/li>\n
  • quality control departments<\/li>\n
  • research laboratories<\/li>\n<\/ul>\n

    EN 933-3 Standard<\/h2>\n

    The Flakiness Sieve Set<\/strong> supports testing according to EN 933-3<\/strong>, which covers the determination of aggregate particle shape by means of the flakiness index.<\/p>\n

    The standard method evaluates specified aggregate size fractions separately before calculating the overall flakiness index.<\/p>\n

    Using the correct bar sieve aperture for each fraction is therefore an important part of the test procedure.<\/p>\n

    Complete Set or Individual Sieves<\/h2>\n

    Users can select individual Flakiness Bar Sieves according to their laboratory requirements or choose the LT-A0012\/S Complete Set<\/strong>.<\/p>\n

    Each individual sieve measures approximately 34 \u00d7 32 \u00d7 8 cm<\/strong> and weighs approximately 4 kg<\/strong>.<\/p>\n

    The complete set measures approximately 34 \u00d7 32 \u00d7 104 cm<\/strong> and weighs about 52 kg<\/strong>.<\/p>\n

    Overall, the Flakiness Sieve Set<\/strong> provides a durable and modular solution for determining aggregate flakiness according to EN 933-3<\/strong>, with aperture sizes ranging from 2.5 mm to 50 mm<\/strong>.[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
