Aromatic Plasticizer Concrete Admixture
A liquid additive for cement and concrete mixes containing over 5% aromatic substances like alkylbenzene sulfonates to improve workability and reduce water demand. It falls under HTS 3824.40.10.00 due to its high aromatic content used as a prepared additive for concretes. This ensures better flow and strength in construction applications.
Polystyrene-Based Cement Dispersant
A powdered dispersant with modified polystyrene (aromatic polymer) exceeding 5% by weight, added to concrete to prevent clumping and enhance uniformity. Classified in 3824.40.10.00 for its aromatic-modified substances in concrete preparations. Ideal for high-performance ready-mix applications.
Aromatic Sulfonate Water Reducer for Mortar
Concentrated liquid water-reducing agent with sodium naphthalene sulfonate (>5% aromatic) for mortars and concretes, improving strength by minimizing water. HTS 3824.40.10.00 applies due to aromatic substance threshold in prepared additives. Commonly used in tile adhesives and masonry.
Modified Styrene Acrylic Concrete Superplasticizer
High-range water reducer blending styrene (aromatic) and acrylic polymers over 5% by weight for self-compacting concrete. Falls under 3824.40.10.00 as aromatic-containing prepared concrete additive. Enables pumpable mixes with superior slump retention.
