Case Study 2:

Scenario: An architect is planning the construction of a bridge over a river. The structural integrity of the bridge depends significantly on the type of concrete mix selected. The architect needs to consider various factors to ensure the concrete's strength and durability.

Question: What is a crucial factor in determining the quality of concrete mix for the bridge construction?

A. Low compressive strength and rapid setting time B. High water-cement ratio and excessive bleeding C. Adequate curing and proper aggregate grading D. Inclusion of air voids and excessive use of plasticizers
