The property of concrete by which it can be mixed, transported and placed in position with ease is referred to as ______.

• A. Durability
• B. Elasticity
• C. Workability
• D. Toughness

Answer: (C)

Workability describes how easily concrete can be mixed, transported, placed, and finished. It captures the ease with which the mix flows, consolidates, and can be worked into forms and around reinforcement, without excessive vibration or segregation. Factors like the water-cement ratio, aggregate size and grading, temperature, and the use of admixtures influence workability. Too much workability usually means more water or plasticizers, which can reduce strength or cause segregation, while too little makes placement laborious and prone to voids. Durability is about long-term resistance to deterioration, elasticity is about deformation under load, and toughness is about resisting crack propagation. Therefore, the term that fits “mixed, transported and placed in position with ease” is workability.
