Construction chemicals are specialized substances used to enhance the performance, durability, and aesthetics of building materials and structures. These include admixtures for concrete (e.g., accelerators, retarders, and water reducers), sealants, adhesives, waterproofing agents, and protective coatings. They improve properties like strength, workability, and resistance to weathering and chemical attacks. These chemicals are essential for ensuring the longevity and quality of construction projects, adhering to industry standards and regulations for safety and performance.
