THE DETERMINATION OF THE TRETON IMPACT VALUE OF AGGREGATE SCOPE The Treton value is a measure of the resistance of aggregate to impact. The aggregate is subjected to the blows of a falling hammer and the resulting disintegration is measured by means of the quantity passing the 2,0 mm sieve which is then expressed as a percentage of the test sample.

The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value.. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines value” should be determined ...

Consider the following statements: 1. A high aggregate impact value indicates strong aggregates. 2. A low aggregate crushing value indicates high crushing strength of aggregates. 3. Aggregates having elongation index values greater than 16% are generally considered suitable for pavement construction. 4.

The AGGREGATE function is designed for columns of data, or vertical ranges. It is not designed for rows of data, or horizontal ranges. For example, when you subtotal a horizontal range using option 1, such as AGGREGATE (1, 1, ref1), hiding a column does not affect the aggregate sum value. But, hiding a row in vertical range does affect the ...

The Investment Multiplier. The model of Aggregate Expenditures that we are currently considering is often called a Keynesian Model because it was first formulated by British economist John Maynard Keynes in his General Theory of Employment, Interest, and Money, published in 1936—at the height of the great depression. One of the central premises of Keynesian economics is the idea of a multiplier.
