What specific requirement assists in preventing cracks in concrete slabs?

• A. Using high-strength concrete
• B. Installing welded wire mesh
• C. Applying a sealant
• D. Increasing slab thickness

Answer: (B)

Installing welded wire mesh in concrete slabs plays a crucial role in preventing cracks. This type of reinforcement helps distribute loads and tensile stresses more evenly across the slab surface. When the concrete undergoes temperature changes or moisture variations, it expands and contracts. Without proper reinforcement, these movements can lead to cracking as the tension exceeds the concrete’s capacity to withstand it. Welded wire mesh acts as a supportive framework within the concrete, enhancing its structural integrity. This reinforcement can mitigate the development of cracks by holding the concrete together and resisting internal stress caused by environmental factors. By effectively reinforcing the concrete, welded wire mesh allows the slabs to accommodate thermal expansion and contraction, thereby enhancing their durability. While other options may contribute to the overall performance of concrete, welded wire mesh specifically addresses the issue of cracking by providing tensile strength where concrete naturally lacks it.
