202036At first glance All you need is a GROUP BY clause with the MAX aggregate function. SELECT id MAXrev FROM YourTable GROUP BY id Its never that simple is it I just noticed you need the content column as well.. This is a very common question in SQL find the whole data for the row with some max value in a column per some group identifier.

The crushed aggregate is allowed to pass through 2.36 mm IS sieve. And the impact value is measured as percentage of aggregates passing sieve W2 to the total weight of the sample W1. Aggregate impact value W1W2100. Aggregates to be used for wearing course the impact value shouldnt exceed 30
Ii the percentage by weight of the total sample passing through one sieve and retained on the next smaller sieve to the nearest 0.1 percent. The results of the sieve analysis may be recorded graphically on a semilog graph with particle sie as abscissa log scale and the percentage smaller than the specified diameter as ordinate.

Determine of Aggregate Impact Value Test BS 812. Experiment Name Determine of Aggregate Impact Value Test BS 812 Purpose of the test The Impact value of an aggregate is the percentage loss of weight particles passing 2.36mm sieve by the application of load by means of 15 blows of standard hammer and drop under specified test condition.
2 The California Bearing Ratio TestCBR test is a penetration test that can be performed in the laboratory or insitu. They can be considered as small scale bearing tests in which the ratio of penetration to the sie of the loaded area is much greater than in bearing tests.

Of strength could be due to PKS having lower strength when compared to normal aggregate. This is reflected from the impact value for normal aggregate which is double that of PKS see Table 1. Another factor that may cause the decrease could be attributed to the highly irregular shapes of the

Step11 Sieve the crushed aggregate through 2.36 mm IS sieve and weigh the fraction passing through it to an accuracy of 0.1 gram. This fraction is a measure of loss of material due to crushing. The mean value of two samples rounded to nearest whole number is taken as the aggregate crushing value. Observation and Calculation
