TRUNNANO launches powder foaming agent for lightweight concrete

TRUNNANO says it has introduced a solid powder foaming agent aimed at solving transportation, storage and handling problems tied to liquid foam additives. The product is designed for foamed concrete, aerated blocks, lightweight panels and specialty mortars, with claimed gains in strength, logistics efficiency and export readiness.

Why it matters: - TRUNNANO’s new powder foaming agent targets a core bottleneck in lightweight concrete: how to move, store and mix foaming additives without sacrificing performance. - The product is positioned for projects where liquid foaming agents are costly or difficult to use, including remote infrastructure work and export markets. - The formulation is intended to support lower-density concrete while reducing the strength loss that often comes with lighter mixes.

What happened: - TRUNNANO, the concrete-admixtures business of Luoyang Tongrun Info Technology Co., Ltd., introduced a solid powder foaming agent for lightweight concrete production on Sept. 3, 2026, in Luoyang, China. - The product is now available for foamed concrete, aerated blocks, lightweight panels and specialty mortars. - The company says the powder form is dust-free, non-flammable and stable at room temperature.

The details: - The product uses a composite surfactant system and carrier loading technology. - Active ingredients are loaded onto solid carriers through spray granulation, then dried, crushed and sieved. - The result is a free-flowing powder that releases active components when mixed with water. - The carrier material comes from mineral-based inputs. - Specialized stabilizers are designed to create bubbles in the 0.1–0.5 mm range with thicker walls. - TRUNNANO says that bubble structure helps reduce coalescence during mixing and placement. - Independent laboratory tests indicated compressive strength 15% to 20% higher than equivalent liquid foaming agents at the same concrete density level. - The company says the material releases no irritating gases, no harmful substances and carries no flammability or explosion hazard. - TRUNNANO says the product has met REACH and RoHS compliance requirements.

Between the lines: - The release frames the product as a logistics fix as much as a materials product. - Liquid foaming agents can be expensive to transport, especially when projects sit far from manufacturing sites. - The release cites industry data showing transportation can make up 30% to 50% of total procurement costs for projects more than 500 kilometers from production facilities. - It also says liquid agents in tropical climates can lose up to 40% of foaming capacity after six months of storage. - Those constraints have limited use in remote and cross-border projects, which helps explain the push toward a dry format. - TRUNNANO also positions the powder as easier to handle in automated batching and factory production settings.

What's next: - The powder foaming agent is being offered for foamed concrete used in roof insulation, underfloor heating, bridge abutment filling and foundation backfilling. - Project data from trial applications showed material cost savings of 10% to 20% tied to lower shipping weight and less waste from leftover diluted liquids. - The product is also aimed at aerated blocks and panels, precast lightweight partition panels and hollow core slabs. - For mortars, the formulation is described as compatible with polycarboxylate superplasticizers, retarders and accelerators. - The product ships in bags, which allows standard container transport without hazardous-material declarations required for liquid surfactants. - Recommended dosage is 0.05% to 1.0% of cementitious materials by weight, with final use based on target density and trial-mix results. - Users can apply either the dry-mix method or a pre-dissolution method depending on site conditions.

The bottom line: - TRUNNANO is betting that a safer, easier-to-ship powder can widen the use of foamed concrete while improving consistency and lowering logistics costs.
