Curing processes refer to methods used to harden or stabilize materials, particularly in construction and manufacturing. This can involve the application of heat, moisture, or chemical agents to enhance the properties of materials like concrete or rubber. The goal is to improve strength, durability, and resistance to environmental factors. In the case of concrete, curing typically involves keeping the material moist for a specific period after pouring. This helps prevent cracking and ensures proper hydration of the cement. For rubber, curing often involves heating with sulfur, which creates cross-links between polymer chains, resulting in a more resilient final product.
