Chapter 5, Problem 5.27QP
Table P5.27 shows the grain size distributions of two aggregates A and B.
Answer the following questions and show all calculations:
a. What are the maximum sizes of aggregates A and B?
b. Is aggregate A well graded? Why?
c. Is aggregate B well graded? Why?
Note: In order to answer questions b and c, you need to plot the gradations on 0.45 gradation charts. You may create 0.45 power gradation charts using Excel or you may manually plot the data on a copy of Figure A.25.

1. In the specific gravity and absorption experiment, the following measurements were taken of
coarse aggregates:
Weight of pan used to weigh SSD aggregates
Weight of pan + SSD aggregates
Weight of SSD aggregates in water
Weight of pan used to weigh oven-dried aggregates
Weight of pan + oven dried aggregates
Calculate the following properties:
a. Specific gravity
b.
SSD specific gravity
c. Apparent specific gravity
d. Absorption
= 500 g
= 2550 g
= 1300 g
= 510 g
= 2545 g
2. After manually sieving 100 g of cement on the No. 200 sieve, the mass retained on the sieve was
found to be 8 grams. Determine the fineness of the cement.
Table shows the grain size distributions of aggregates A, and B. Answer the following questions and show all calculations:
What are the maximum sizes of aggregates A and B?
