Then, for the aggregation portion, we need to find all the unique terms in Doc_1 and Doc_2.Trying to do this with the inverted index would be a very expensive process: we would have to iterate over every term in the index and collect tokens from Doc_1 and Doc_2 columns. This would be slow and scale poorly: as the number of terms and …

Sampling of Aggregates. Select coarse aggregate that passes through a 12.5mm IS sieve and is retained on a 10mm IS sieve. Heat the aggregate at 100 to 110°C for 4 hours, cool it to room temperature, and ensure that the material depth in the cylinder, after tamping as described below, is 10 cm. Determine the appropriate quantity by filling …
to calculate the load required to produce 10% fines. Force required to produce 10% fines = 14 x X y + 4 where X and y are as above. 3. Reporting of Results 3.1 Calculate the mean of the two results to the nearest 10kN for forces of 100kN or more, or to the nearest 5kN for forces of less than 100kN. Report the mean as the 10% Fines Value, unless the
d) Aggregate Crushing Value/Ten Percent Fines Value. The coarse part of the material sampled and tested in accordance with STP 7.7.1 and 7.7.2 shall have Aggregate Crushing Values (ACV) and ten percent fines values as follows: ACV (%) Ten percent fines Base Type I Less than 30% Greater than 125 kN Base Type II Less than 35% Greater than 90 …
The ten percent fines value is a measure of an aggregate's resistance to crushing. The standard test method involves compacting a sample between two plates and applying a force over 10 minutes to achieve a specified …
aggregate and those fraction from 4.75 mm to 150 micron are termed as fine aggregate. The size 4.75 mm is a common fraction appearing both in coarse aggregate and fine aggregate (C.A. and F.A.). Grading pattern of a sample of C.A. or F.A. is assessed by sieving a sample
Aggregate is classified as either fine or course aggregate depending on the sizes of the material. Aggregate that pass through a 5mm sieve are known as fine ... (ACV), Ten percent Fine Value (TFV), Elongation Index (EI) and Flakiness Index (FI). Aggregate properties in BBDMP showed better results than that of SIP and RJKIP. From the study, …
Numeric types, date types, the boolean type, ip type, geo_point type and the keyword type can also be queried when they are not indexed but only have doc values enabled. Query performance on doc values is much slower than on index structures, but offers an interesting tradeoff between disk usage and query performance for fields that are only …

value the weaker the aggregate. An ACV greater than 35% indicates that aggregate is too weak for most construction uses. A variation is the Ten Per Cent Fines Value (TFV) which is expressed as the load required to produce 10% fines. TFV ranges from 10 kN (very weak rock) to greater than 400 kN (very strong rock).
The 10% fines value is a metric that gauges the ability of aggregates to withstand crushing under loading, and it is applicable to both weak and strong …

This document gives the test method for determination of ten percent fines value (TFV) of aggregates. This method gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load. It covers two sets of procedures: — the first procedure is applicable for aggregates tested in dry condition; and
Testing aggregates - Part 111: Methods for determination of ten per cent fines value (TFV. ... 1.0 AGGREGATE IMPACT VALUE TEST 1.0 INTRODUCTION Aggregates used in road construction, should be strong enough to resist crushing under traffic wheel loads if the aggregates are weak, the stability of the pavement structure is likely to be adversely ...
In cases where the aggregate crushing value is 30 or higher, the result may be anomalous, and therefore, the ten percent fines value should be determined instead. The purpose of conducting this test is to determine the aggregate crushing value of coarse aggregates and evaluate their suitability for use in various types of roads.
