Question

Mix the aggregates given the results of sieve analysis test in Table 1 in appropriate proportions, show the granulometry curves of each aggregate and mixture in Figure 2, calculate the fineness modulus (FM) of the mixture.

Sieve Size (mm)	31,5	16	8	4	2	1	0,5	0,25
A1(Passing) %P1	100	90	85	55	10	0	0	0
A2 (Retained, g)	0	0	0	0	200	300	200	100
A3(100-%P3)	0	60	95	100	100	100	100	100

Answer 1

Column 1	Column 2	Column 3 = 100-column 2	Column 4 ,column 3 is changed into individual	Column 5	Column 6, % calculated	Column 7	Column 8, cumulative converted into normal	Column 9	Column 10
Sieve Size	A1	A1	A1	A2	A2	A3	A3	Mixutre	Mixture cumulative retained
mm	%P1	% cumulative retained	% retained	RETAINED G	% retained	100-P, %	% retained	% retained of (A1+A2+A3)/3	%
31.5	100	0	0	0	0.00	0	0	0.00	0
16	90	10	10	0	0.00	60	60	23.33	23.33
8	85	15	5	0	0.00	95	35	13.33	36.67
4	55	45	30	0	0.00	100	5	11.67	48.33
2	10	90	45	200	25.00	100	0	23.33	71.67
1	0	100	10	300	37.50	100	0	15.83	87.50
0.5	0	100	0	200	25.00	100	0	8.33	95.83
0.25	0	100	0	100	12.50	100	0	4.17	100.00
								∑	463.33
