Unless the context otherwise requires, the following terms, when used in the rules contained in this regulation or in Regulation 13A or 15D or in the forms for statements and reports filed pursuant to sections 12, 13 or 15 (d) of the act, shall have the respective meanings indicated
This Apparatus is used to determine aggregate impact value of coarse aggregate. The hammer of the tester fall freely from 380 mm height on coarse aggregate for 15 times/15 sec.the crushed aggregate removed from the cup ,then sieved and weighed. The % ratio of the weight passing 2.36mm sieve and weight of oven dried sample is Aggregate Impact value
It gives the correct value because that column does not contain hidden rows, errors & nested subtotals. Here will calculate the SUM using an AGGREGATE function in cell B19. =AGGREGATE (9,4,B8:B16), The result will be 487. Function_ num: For SUM function, the function_ num is 9. Option: In Column B, i.e
