(a) In terms of relative strength, put fcd (design strength of concrete), fck
(characteristic strength of concrete) and fcm (mean strength of
concrete) in order from lowest to highest strength. (3)
(b) Approximately, what is the tensile strength of concrete as a
percentage of its compressive strength? (1)
(c) Draw and name all necessary reinforcement for the simply supported
beam and static loading case shown at Figure 3a. (6)
(d) Recreate the table in Figure 3b in your script books and fill in by
writing “Poor” and “Good” words to describe the property of the
material.

Expert Solution

a) fm( mean strength ) > characterstics strength > desighn strength

Expalantion-

fm = fck+1.6σ

where fck is characteristic strength

fd (design strength ) will be fck/f.o.s(factor of safety)

b) tensile strength of concrete is 10% of compressive strength of concrete

in question c and d figure is necessary to find the value

Strength of concrete: The compressive strength, in kilopascals, was measured for concrete blocks from five different batches of concrete, both three and six after pouring. The data are as follows. Can you conclude that the mean strength after three days is less than the mean strength after six days? Let U1 represent the mean strength after three days and ud=u1-u2, Use the a=0.01 level and the critical value method with the table. 1. State the appropriate null and alternate hypotheses....
