5.17 Calculate the sieve analysis of the following aggregate and plot on a semilog gradation paper. What is the maximum size? What is the nominal maximum size? Sieve Size 25 mm (1 in.) 9.5 mm (3/8 in.) 4.75 mm (No. 4) 2.00 mm (No. 10) 0.425 mm (No. 40) 0.075 mm (No.200) Pan Amount Cumulative Amount Cumulative Percent Retained, g Retained, g 0 47.1 239.4 176.5 92.7 73.5 9.6 Retained Percent Passing

There are two sources of aggregates (A, B). A sample has been taken from both sources and measured their mass as shown in table below. Measurement Wet mass (9) Oven-dry mass (g) Aggregate A 500 480 Aggregate B 600 564 (a) Determine the total moisture content for the samples from both aggregate sources, respectively. (b) Determine the total moisture content for an aggregate blend with 30% of aggregate A and 70% of aggregate B.

if total sample mass of aggregate is 164.9 grams, then the percent passing from sieve size #30 only is equal to ………………

help find a, and b

The table below shows the properties of materials required to design a concrete mix.   It is required to:a- Make a complete mix design.b- Express the proportions by volume for water, coarse aggregate, and fine aggregate, knowning that weight of 1 m3 gravel = 1760 kg/m3 and weight of 1 m3 sand = 1600 kg/m3.c- From the designed mix it is required to make a trial mix enough for six standard cubes (15 cm x 15 cm x 15 cm), six standard cylinders (d = 15 cm, h = 30 cm), and three standard beams (15 cm x 15 cm x 70 cm). what are the proportions of this mix? Using BSI Method only
