Textbook Question
Chapter 5, Problem 5.36QP
Calculate the fineness modulus of aggregate A in Problem 5.27. Is your answer within the typical range for fineness modulus? If not, why not?
5.27 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.
