In this view an attempt has been made to develop a correlation between the various physical characteristics of aggregates from different sources across Kashmir valley and adjoining areas in J&K, so as to develop a mathematical model depicting relationship between other physical characteristics & soundness property of aggregates. 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 . 200) Sieve in Mineral Aggregates by Washing 7. Then the flakiness index is calculated as the total weight of material passed through various thickness gauges, expressed as a percentage of total weight of the sample gauged. SAMPLING Before conducting any test on aggregates, the first thing to do is sampling. You can download the paper by clicking the button above. A high flakiness index test result indicates a high proportion of elongated aggregates, a low test result indicates a low proportion of elongated aggregates. The Elongation Index on an aggregate is =. Participated in project engineering reviews, studies and site investigations. Specifications: Additional Information Item Code AT-215-216 Interested in this product? Particle shape and surface texture influence the properties of freshly mixed concrete more than the Aggregate related testing such as Sieve Analysis, Flakiness & Elongation, Specific gravity & water absorption, Loss Role and Responsibilities Determination of the Specific Gravity and Water Absorption of the Aggregates. must also be increased to maintain the water-cement ratio. Aggregate sample to be tested 3. The mass of the particles retained on the various sieves is related to the initial mass of the material. Elongation index is a aggregate that have length more than 1.8 sieve size. In absence of adequate information from performance studies, a laboratory test simulating accelerated weathering condition is created to judge durability or soundness of aggregates. Maximum permitted elongated index is 35%, 40% or 45% for aggregate size 21/2" - 2", 11/2" - " and 1/2" - ". As such, increasing the conspicuity of traffic signals should lead to improved safety performance. Aggregate related testing such as Sieve Analysis, Flakiness & Elongation, Specific gravity & water absorption, Loss Role and Responsibilities Firstly, 10-20 mm and 5-10 mm of aggregates were mixed in various proportions to find the combination with minimum voids content by Loose Bulk Density Test. These two types of plastic were seen to be satisfactory in improving the properties of flexible pavements. length gauges, expressed as a percentage of the total weight of the sample gauged. Frankly speaking concerned with the procedure of road laying this evil plastic cannot be fully eradicated but we can channelize the waste plastic in improving the bitumen roads and in spite of plastic low polymer wax, waste glasses is also an alternatives for an increment in strength of the road properties, this is not possible to degrade all the waste plastic. Using various softwares (such as NLREG-Nonlinear Regression and Curve Fitting; MRA&F; XLSTAT), a general relationship between the soundness property and other various characteristics of aggregates (from J&K) has been developed. eEF2 allows the ribosome to move down the mRNA one codon at a time by acting a translocase (1). Flakiness & Elongation Index Test Gauges Thickness Gauge (Flakiness Index BS), comprising 4.9x30 - 7.2x40 - 10.2x50 - 14.4x60 - 19.7x80 - 26.3x90 - 33.9x100 mm slot dimensions Flakiness (Thickness) Gauge Used for Determination of flakiness index of coarse aggregates. Follow the Testing of Material as per Indian Standard code (IS-Code). 3.

This test is not applicable to sizes smaller than 6.3mm. 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. Thickness of these particles are comparatively smaller than the other two dimensions. The soundness property test result is one of the important parameter used effectively for such assessment. Flakiness Index = [W 2 / W 1] x 100 Where, W 2 = Weight passed from 0.6 x d mean size W 1 = Total weight of aggregates TriPac (Diesel) TriPac (Battery) Power Management Rough-textured, angular, and elongated particles require more water all-in aggregate-aggregate consisting of a mixture of fine and coarse aggregates. Elongated and flaky stones are normally not very suitable for road works since the shape and the size make them difficult to compact. There are various types of PAAS-private PAAS and public PAAS. A flaky particle is the one whose least dimension (thickness) is than 0.6 times the mean size. 4. Hence we offer thickness gauge and length gauge to check flakiness and elongation index of the aggregate respectively. For that aggregates are collected from extensive areas. Designing , testing and controlling of Concrete Pavement Blocks, Concrete Pipes, among others Testing and evaluation of different sizes of crushed rock ranging from particle size distribution, Flakiness Index, Elongation, Impact test, 10% fines and a host of others. Objective(s) of the Experiment. Definitions (EN 12320) aggregate-granular material used in construction. Well we are very concerned with the present scenario of the world that civilization are being dominated by wastes, thus waste plastic, glasses etc. These are the materials of which the thickness is small as compared to the other two dimensions. But in practice only limited number of such tests could be performed for evaluating these engineering properties because of high cost and time required for testing and as a result, it is difficult to reveal detailed variation in the soundness values to enable rational, economic and also safe construction. Materials that are bound together with bitumen are called bituminous materials. Elongation Index= ( (Total weight of material retained on various length gauges) / (Total Weight of sample taken)) X 100. JFIF ` ` C Note 1-This form is available from the Materials & Tests Division/Soils & Aggregates Section. NDT Test-(compressive strength of concrete & ultrasonicpulse velocity). As a result huge quantity of aggregate material is being needed for the constructions of sub-base in most of the situations. Flakiness index test lab report pdf Flakiness and Elongation Index Test are very important tests to be performed on aggregate in the laboratory. The apparatus shall be consisting of following:-Weight Balance (Digital balance):-Used for weighing the aggregate sample and It shall have an accuracy of 0.1 percent of the weight of the test sample.Elongation or Length gauge:-Used for passing different sizes of aggregate between different size ranges gaps on . As conventional binders have not been able to meet the requirements of special locations such as expressways, bus stops, intersections, etc. The various studies have been conducted on the use of waste materials in road construction technologies but not much efforts have been put and extensive studies have not yet been made by using variety of plastic waste through wet technology i.e. Flaky particles are those whose least dimension is 0.6 times lesser than the mean size. natural aggregate-aggregate from mineral sources which has been subjected to nothing more than mechanical processing. 3.0 Apparatus a. 1.
