Textbook Question
Chapter 6, Problem 6.35QP
Two batches of concrete cylinders were made with and without a calcium chloride (CaCl2) accelerator admixture. Six cylinders were made of each batch and submerged in water for different times before testing for compressive strength and the results are shown in Table P6.35. It is required to do the following:
a. Using an Excel sheet, plot the relationship between curing time and compressive strength of the two mixes on the same graph. Label all axes and curves.
b. Comment on the effect of the accelerator on the compressive strength of PCC at early and late ages.

They are designed to get you out of your classroom or office and develop the skills of designing experiments and collecting data, and then performing calculations, evaluating the results, and communicating your findings. Labs are more than just number crunching - they are about reflecting on what is both practical and technically sound engineering problem-solving. For each problem below, address the scenario presented and develop engineering solutions. Communicate your results using drawings, pictures, and discussion, supported by calculations developed using the Microsoft Equation Editor or similar tool.
