Construction chemicals are specialized chemical formulations used in the building and construction industry to improve the performance, durability, and lifespan of structures. They are not the ordinary materials like cement or aggregate alone, but additives, admixtures, sealants, coatings and repair materials that “enhance” the behaviour of conventional materials (concrete, mortar, plaster etc).
Definition and Scope
Construction chemicals can be defined as chemical products that are used along with building materials (cement, concrete, mortar, bricks, blocks) at the time of construction or repair, with the aim of improving certain properties (workability, strength, waterproofing, adhesion, etc).
Their scope covers:
- Admixtures for concrete and mortar (to adjust setting time, reduce water, improve workability)
- Waterproofing agents (to prevent water infiltration)
- Protective coatings (on floors, walls, steel)
- Sealants and adhesives (for joints, tiles)
- Repair & rehabilitation chemicals (for restoring damaged concrete)
