XRT-ENL
xinrui-te
XRT-ENL01 Sodium Alpha-Olefin Sulfonate (AOS 35%) is a high-performance anionic surfactant widely adopted as a concrete air-entraining agent and cleaning raw material.This light yellow transparent liquid contains 34–36% active matter, featuring outstanding foaming stability, strong detergency and excellent hard water resistance. XRT-ENL01 exhibits excellent compatibility with cement and other admixtures, ensuring consistent air content control even in variable site conditions. Its superior foaming stability and calcium soap dispersibility make it ideal for ready-mix, precast, and high-durability concrete projects. Biodegradable and low in residual alkali, it meets modern environmental and safety standards.

Stable & Persistent Foaming – Generates abundant, fine, and uniformly distributed bubbles that resist coalescence and collapse. Maintains consistent air content throughout the entire concrete mixing, transport, and placement process.
Precise Air Content Control – Exhibits strong compatibility with cement and various admixtures. Bubble volume remains stable even when site water temperature or aggregate gradation fluctuates, ensuring reliable and controllable performance.
Excellent Calcium Soap Dispersibility & Hard Water Resistance – Calcium and magnesium ions present in aggregates and mixing water do not destabilize the bubbles. Normal air entrainment is sustained even under high‑hardness water conditions.
Normal dosage is 0.01%-0.06%
Application | Dosage Range (% of cementitious materials) | Target Air Content |
Standard frost-resistant & pumped ready-mix concrete. | 0.01% – 0.03% | 4% – 5% uniform micro bubbles. |
Severe cold regions, bridge decks, pavements, high salt-frost resistance concrete. | 0.03% – 0.05% | Slightly higher to meet freeze-thaw durability. |
Low cement content, high fly ash, manufactured sand, or hard water conditions. | Trial-mix adjustment required; maximum 0.06% |

Recommended wet addition: Fully dilute this product in mixing water first, then pour the mixture into the mixer. This creates even, stable microbubbles for optimal air-entraining effect.
Dry adding is prohibited: Never pour directly onto dry cement or aggregates. It will cause uneven bubble size and local excessive foaming.
Mix with water reducers: It mixes well with polycarboxylate and naphthalene water reducers in mixing water. No separate feeding needed.
Sufficient mixing time is required, minimum 90 seconds. Short mixing leads to low air content; over-mixing breaks bubbles and reduces air volume. Use shorter mixing time at high temperatures.
Sealed in 200kg plastic drums, store in cool places at 0–40℃, avoid freezing and direct sunlight. Slight thickening at low temperatures is normal; stir with warm water to restore performance.
