The flaky particles can affect the durability of concrete as they tend to be oriented in one plane, with water and voids forming underneath. The presence of flaky or elongated particles in excess of 10-15% of the weight of coarse aggregate is undesirable. The test is carried on aggregate sizes between... OPERATING MANUAL | HM-925 Thickness Gauge (Flakiness … The Flakiness Index is determined by separating the flaky particles and expressing their mass as a percentage of the total mass of the sample.Under such circumstances, the appropriate correction factor must be applied to determine the mass of flaky particles had the entire size-fraction been... Flakiness and elongation index of aggregate 3: Thickness Gauge- For Flakiness Index. Thickness Gauge have width equal to 0.6 times the3, or in bulk on sieves having elongated slots. The width of the slot used in the gauge or sieve shall be of5. The Flakiness Index is the total weight of the material passing the various thickness gauges or...

Determining Flakiness Index - ftp.dot.state.tx.us DETERMINING FLAKINESS INDEX TxDOT Designation: Tex-224-F Effective Date: August 2016 1. SCOPE 1.1 Use this test method to determine the percentage of particles in a coarse aggregate material that have a thickness (smallest dimension) of less than one-half of the nominal size. Thickness Gauges (Flakiness Index) - Gilson Co. Gilson offers two Stainless Steel Flakiness Index Gauges. Both are heavy-gauge stainless steel with precision laser-cut openings and etched size markings for each slot. HM-925 Thickness Gauge meets BS-812 specifications and features seven slots for rapid hand trying of particles from each of the seven sieve fractions from 2.5 to 0.25in (63 to 6 ... 7.3.

FLAKINESS INDEX OF AGGREGATES ITM No. 224-18. 1.0 SCOPE. 1.1 This test method describes a procedure to determine the Flakiness Index (FI) of aggregates. The FI is used as a design input to determine the rate of application of aggregate and asphalt material for seal coats.
How can the answer be improved? TMH1 - Method B3T - CSIR METHOD B3T TENTATIVE METHOD FOR THE DETERMINATION OF THE FLAKINESS INDEX OF A COARSE AGGREGATE SCOPE. The Flakiness Index of a coarse aggregate is determined by gauging screened-out fractions with the appropriate slot(s) given in Table I below. Aggregate retained on the 75 mm and passing the 4,75 mm sieve is not included in the test. Definition. Flakiness and Elongation - pcte.com.au The accuracy of the slot size is better than 0.1 mm. UTA-0410 Flakiness Index Sieve Set consists of 7 sieves. For sample preparation 6.3, 10, 14, 20, 28, 37.5, 50 and 63 mm aperture sizes test sieves should be ordered separately. SD 203 Method of Test for Flakiness Index
Theory of Flakiness Index and Elongation Index Tests. This test is not applicable to sizes smaller than 6.3mm. The Elongation index of an aggregate is the percentage by weight of particles whose greatest dimension (length) is greater than nine-fifths (1.8times) their mean dimension. This test is not applicable for sizes smaller than 6.3mm. 1223.1 1223.2 APPARATUS A. conforming to the design and 1223.5 CALCULATIONS FOR AN INDIVIDUAL SIEVE SIZE % Flakiness Index = A x 100 A + B Where: A = Weight passing a given slot B = Weight retained on the same slot Report Flakiness Index to the nearest whole number. 2 = Weight retained on the same slot Report Flakiness Index to …
