Chapter 7, Problem 7.44QP
Three batches of concrete were prepared using the same materials and ingredients, except that they have water-cement ratios of 0.50, 0.55, and 0.60, respectively. The following tests were performed on specimens made of the three batches:
- Compressive strength test on 4″ × 8″ cylinders
- Center-point flexure test on 4″ ″ 4″ × 12″ beams
- Split tension test on 6″ × 12″ cylinders
Three replicates were tested for each test. Table P7.44 shows the average failure loads for the three replicates of each case.
It is required to do the following:
- a. Complete Table P7.44
- b. Using an Excel sheet, plot the relationships between water-cement ratio and compressive strength, modulus of rupture, and tensile strength on the same graph. Label all axes and curves.
- c. Comment on the effect of water-cement ratio on the compressive strength, modulus of rupture, and tensile strength.

A reinforced concrete beam with b=300mm, h=670mm,and d=600 mm, having
a span of 7.3 m, can be considered as a fully fixed at the left support and simply
supported at the right end. It is reinforced for positive bending with 8-16 and for
negative bending with 4816 plus 418. Calculate the collapse load using the plastic
hinge method. (20%)
