Understanding Cracks in Reinforced Concrete
Reinforced concrete forms the core of large structures. However, the appearance of cracks compromises the aesthetics and integrity of the work. Therefore, WGB Engenharia uses advanced technologies to mitigate these problems from the design phase. In this way, we guarantee durability and safety.
Plastic Retraction: Immediate Action
Plastic shrinkage occurs soon after concreting. At this stage, water evaporates rapidly from the surface. Furthermore, lack of protection from wind or sun accelerates the process. As a result, irregular surface cracks appear. Therefore, immediate wet curing is essential.
Thermal Shrinkage: The Challenge of Large Volumes
The chemical reactions in cement release intense heat. For example, in thick concrete elements, the core heats up while the surface cools. Due to this difference, severe internal stresses occur. Consequently, the concrete cracks. To avoid failures in complex projects, such as the iconic towers near the... South Barra Pier, We use heat-reducing additives and strict temperature control.
Technologies and Standards Applied
A NBR 6118 It establishes strict parameters for the calculation and control of cracking. On the other hand, technology has evolved. Currently, we employ state-of-the-art additives that intelligently control shrinkage. In addition, the application of polypropylene fibers reinforces the concrete matrix. In this way, we drastically reduce the opening of cracks. Furthermore, the optimized mix design reduces the permeability of the material.
Good Engineering Practices
Execution demands attention to detail. First, perform the concrete pouring under controlled weather conditions. Equally important is proper compaction to avoid voids. Finally, curing must be maintained for extended periods according to current standards. In short, technical rigor defines the longevity of your construction.
