🛠️ Civil Engineering Site Knowledge | Concrete Placement Quiz

How strong is your civil engineering knowledge? Test yourself with this practical site engineering question that every civil engineer, site engineer, QA/QC engineer, structural engineer, construction supervisor, and engineering student should know.

Question:
What is the standard unit of compressive strength?

Options:
A) kg
B) N
C) MPa (N/mm²)
D) mm

Compressive strength is one of the most important properties used in concrete testing, reinforced concrete (RCC) design, quality control, structural engineering, construction management, and building inspection. Understanding the correct unit is essential for reading concrete test reports, cube test results, mix design specifications, and international construction standards. Whether you're preparing for civil engineering interviews, competitive exams, university tests, or professional site work, mastering these engineering fundamentals helps improve technical knowledge and decision-making on construction projects.
