The Flakiness index of aggregates is the percentage by weight of particles whose least dimension (thickness) is less than three- fifths (0.6times) of their mean dimension. Generally, flat and elongated particles are w !1AQaq"2B #3Rbr 2 OBJECTIVE. where high performance bituminous mixes are needed, use of variety of virgin polymers and plastics is well proven. The Flakiness Index on an aggregate is = Total weight passing Flakiness Gauge x 100 / Total weight of test sample =_____(%) 2. There are various types of PAAS-private PAAS and public PAAS. The Flakiness index of aggregates is the percentage by weight of particles whose least dimension (thickness) is less than three- fifths (0.6times) of their mean dimension. Characteristics of PAAS are mainly used to test, implement, develop, and maintain applications. Elongation index iii.

The Flakiness Index is the total weight of the material passing the various thickness gauges or sieves, expressed as a percentage of the total weight of the sample gauged. Flaky particles are those whose least dimension is 0.6 times lesser than the mean size. # preparing the summary report and test report for submission to the resident engineer. Gradation v. Aggregate Impact Value vi . The total amount passing the gauge shall be weighed to an accuracy of at least 0.1 percent of the weight of the test sample. Furthermore, you can find the "Troubleshooting Login Issues" section which can answer your unresolved problems and equip you with a lot of relevant information. Elongated and flaky stones are normally not very suitable for road works since the shape and the size make them difficult to compact. It was found among other findings that aggregate characteristics such as; shape, texture and grading contribute significantly to the performance of fresh portland cement concrete. natural aggregate-aggregate from mineral sources which has been subjected to nothing more than mechanical processing. A flaky particle is the one whose least dimension (thickness) is than 0.6 times the mean size. The present study has been undertaken by keeping five important goals in mind these are (i) Environmental protection (ii) sustainable waste minimization (iii) improved durability of roads (iv)Resources/Energy conservation (v) Economy of road. Maximum permitted elongated index is 35%, 40% or 45% for aggregate size 21/2" - 2", 11/2" - " and 1/2" - ". be that specified in co1. Length Gauge have length equal to 1.8 times the mean dimension of the aggregate. % Particle shape and surface texture influence the properties of freshly mixed concrete more than the As such, increasing the conspicuity of traffic signals should lead to improved safety performance. The sample shall be sieved with the sieves specified in Table 1: Separation of Flaky material- Each fraction shall be gauged in turn for thickness $4%&'()*56789:CDEFGHIJSTUVWXYZcdefghijstuvwxyz ? As a result huge quantity of aggregate material is being needed for the constructions of sub-base in most of the situations. What is Elongation Index 4. In absence of adequate information from performance studies, a laboratory test simulating accelerated weathering condition is created to judge durability or soundness of aggregates. Well we are very concerned with the present scenario of the world that civilization are being dominated by wastes, thus waste plastic, glasses etc. to determine the elongation index of the given aggregates. A metal gauge plate '' sieve. Test Method for Soundness of Aggregates by Use of Sodium Sulphate or Magnesium Sulphate 12. The test flakiness index of aggregate is used to determine the particle shape of the aggregate specimen and each particle shape being preferred under specific condition. CONTENTS. is everywhere from a single plastic bag at a shop to a manufacturing automobiles company ,electronic, communication etc. pieces of any fraction to be tested. There are some apparatus which is used for Elongation Index Test. Two types of plastic were taken thermoplastics and thermoset having their relationship with the heat i.e. endobj This test gives the percentage of flaky and elongate aggregate present in the total aggregate sample. were used even for the prehistoric times. The aggregate to be classified is separated into seven sieve fractions from 6,3 to 63 mm. . gauges or sieves, expressed as a percentage of the total weight of the sample gauged. As such the flakiness and elongation test must be carried out to determine the suitability of the material. According to the result shown in Fig 1, 64:36 ratios of 10-20 mm and 5-10mm were selected. The flakiness of aggregate is determined by measuring the thickness of individual particles. It was also found that aggregate blends well with well-shaped, spherical, cubical, rounded and smooth particles that require less cement and water for a given slump than it blended with flat, elongated, angular and rough particles. An aggregate is said to be elongated if its largest lateral dimension is greater than 1.8 times the mean dimension. Mauritius. The cement concrete materials whose geometric characteristics were tested were fine and coarse aggregates. Participated in project engineering reviews, studies and site investigations. The different laboratory test was conducted to determine the Individual properties like Aggregate crushing value, Impact value, Specific Gravity, Los Angeles Abrasion, Flakiness Index, Elongation . Flakiness and Elongation Index Test are very important tests to be performed on aggregate in the laboratory. %PDF-1.4 1. Thickness/Flakiness Index Gauge 2.

Aggregate = 0.2064 1 = 20.64 % X 100 X 100 Average Flakiness Index (%) = Summation of all fractions No. their thickness is less than 0.6 of their nominal size. PRECAUTIONS Take care while taking sample. recycled aggregate-aggregate resulting from the processing of inorganic material previously used in construction. NDT Test-(compressive strength of concrete & ultrasonicpulse velocity). This test gives the percentage of flaky and elongate aggregate present in the total aggregate sample. Consequently, the cement content Get Latest Price from the seller Contact Seller The elongation index is the total weight of the material retained on the various 2 0 obj fines-particle size fraction of an aggregate which passes the 0,063 mm sieve. A high flakiness index test result indicates a high proportion of elongated aggregates, a low test result indicates a low proportion of elongated aggregates. change of state. Determination of Particle Size Distribution Sieving Method (EN 933-1) In a sieve analysis, a sample of dry aggregate of known weight is separated through a series of sieves with progressively smaller openings.
