Construction chemicals play a critical role in modern construction, ensuring enhanced durability, performance, and sustainability of structures. Whether for residential, commercial, or infrastructure projects, the right construction chemicals can improve workability, extend life cycles, and optimize costs.

What Are Construction Chemicals?

Construction chemicals refer to a wide range of chemical formulations used with cement, concrete, or other construction materials at various stages of construction to achieve specific performance characteristics. These chemicals are essential for enhancing strength, reducing water permeability, accelerating curing, improving bonding, and providing protection against environmental factors.

Common Types of Construction Chemicals

TJCY offers a full portfolio of high-quality construction admixtures tailored for various applications. Some of the most widely used types include:

Concrete admixtures

Additives added during the mixing process of concrete to improve the properties of concrete (such as workability, setting time, strength, durability, etc.).

Common types:

Plasticizers/Superplasticizers: Improve fluidity, reduce water consumption, and increase strength.

Retarder/early strength agent: Control setting time and accelerate or delay hardening.

Air entraining agent: Introduce fine bubbles to improve frost resistance.

Expansion agent: Used to compensate for concrete shrinkage and prevent cracking.

Antifreeze agent: Used during construction under low temperature conditions to prevent concrete from freezing.

Application:

Used in concrete projects such as roads, bridges, tunnels, high-rise buildings, and prefabricated components.

Waterproofing agent

Material used to prevent water absorption and water seepage in building structures, which can be mixed into building materials or applied to the surface.

Common types:

Blended waterproofing agent: Added in concrete or mortar to form a dense structure.

Film-coated waterproofing agent: Such as polyurethane waterproof coatings, acrylic emulsions, etc., directly applied to the surface of the structure.

Permeable crystal type: Insoluble crystals are formed inside the structure through chemical reactions to prevent water penetration.

Application:

Basements, roofs, pools, bathrooms, tunnels and other areas that require waterproofing.

Produts：Calcium Stearate  Zinc Stearate  Sodium Oleate

Cement Additives

Chemical or mineral substances added to cement to optimize its performance or reduce costs.

Common types:

Mineral admixtures: such as fly ash, slag, silica fume, etc., to improve cement performance, environmental protection and energy saving.

Grinding aids: Improve cement grinding efficiency.

Retarding/early strength additives: Adjust cement setting speed.

Application:

Applicable to various types of cement products, concrete engineering, special cement, etc.

Application:

Interior and exterior walls, ceilings, floor linings, etc. of residential, commercial buildings, and industrial plants.

Products：

Adhesive

Melamine

Urea

Grouting material

Building materials with strong fluidity and high strength, used to fill structural gaps, fix equipment, etc.

Common types:

Non-shrinkage grouting material: fills the gap between the equipment foundation and concrete to provide support.

Pressed grouting material: used to repair cracks in concrete structures.

Self-leveling grouting material: suitable for floor leveling.

Application:

Equipment foundation, bridge bearings, track bed, concrete crack repair, etc.

Surface treatment agent and sealant

Used for the treatment and protection of building surfaces, enhance durability and aesthetics, prevent water seepage, dust, etc.

Common types:

Surface hardener: such as lithium-based and sodium-based hardeners, improve the strength and wear resistance of concrete floors.

Sealers: seal the pores of concrete to prevent liquid penetration.

Anti-graffiti coatings, anti-corrosion coatings: improve pollution resistance and chemical resistance.

Applications:

Industrial floors, warehouses, indoor and outdoor surfaces of commercial buildings.

Adhesives and repair mortars

Specialized materials used for bonding old and new concrete and material repair.

Common types:
