Construction Chemical Additives

Lotus International Group LLC is a U.S.-based supplier of construction chemical additives sourced from China for businesses across the United States and Latin America.

We supply defoamers, plasticizers, concrete admixtures, retarders, and dispersants for concrete production, dry-mix manufacturing, and construction chemical formulation. Tell us your application, required quantity, and delivery destination to discuss suitable product options and request a quotation.

Construction Chemical Additives for Your Application

Choosing a construction additive starts with the requirements of your mix: workability, setting time, air control, particle dispersion, or a combination of these properties.

Explore the product groups below to identify the right starting point. If you are unsure which additive you need, include your application and performance requirements in your inquiry.

Defoamers & Air Release Agents

Foam-control additives for managing unwanted foam and entrapped air in cement-based formulations. Depending on the grade and application, defoamers can help reduce surface defects and support a more consistent finish. Discuss powder or liquid options for dry-mix mortars, self-leveling compounds, grouts, and other construction formulations

Plasticizers & Superplasticizers

Water-reducing additives for improving concrete workability and supporting the required balance between flow and water content. Our catalog covers lignosulfonate, naphthalene sulfonate, melamine sulfonate, and polycarboxylate ether technologies. Grade selection depends on your cement system, production conditions, and performance targets.

Concrete Admixtures

Explore the broader range of additives used to adjust the fresh and hardened properties of concrete, including water reduction, setting control, air management, and viscosity modification. This category is a starting point for buyers evaluating several performance requirements across ready-mix, precast, and other concrete applications.

Retarders

Set-control additives for applications that require a longer working window before concrete or mortar begins to set. Discuss retarder options for hot-weather placement, extended transport times, and production processes where setting behavior needs careful adjustment.

Dispersants

Additives that help distribute fine particles within a formulation and reduce agglomeration. Suitable grade selection can support flow, consistency, and processing in systems containing cement, fillers, or pigments. Applications include dry-mix mortars, tile adhesives, grouts, and other mineral-based formulations.
