Which of the following indicates poor finishing of concrete?

• A. Even surface texture
• B. Discoloration and visible surface defects
• C. High compressive strength
• D. Minimal cracking

Answer: (B)

Discoloration and visible surface defects indicate poor finishing of concrete because these issues can arise from various factors such as improper curing, inadequate mixing, or application techniques. When the finishing process is not executed correctly, it can lead to an uneven surface, which not only affects the aesthetic appeal but can also reduce the durability and performance of the concrete. Proper finishing should result in a uniform and consistent appearance, with a smooth texture and no visible flaws. Discoloration can also signal problems such as water-cement ratio issues or the introduction of contaminants during the mixing phase, further highlighting the consequences of inadequate finishing practices. Thus, this option reflects the key signs of poor workmanship in concrete finishing.
