CONCRETE CONSTRUCTION SPECIAL INSPECTOR (CP-21) Concrete inspectors must grasp ACI 301 standards and structural design fundamentals before test day. CP-21 assumes solid knowledge of concrete mix design, reinforcement placement, and curing protocols. You’ll need familiarity with field testing methods like slump and compressive strength procedures. Understanding load paths and why certain placements fail separates prepared candidates from those caught off guard by scenario-based questions.
