Textbook Question
Chapter 6, Problem 6.36QP
Two batches of concrete cylinders were made with and without a calcium chloride (CaCl2) accelerator admixture. Five 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 P6.36.
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.
