This non-toxic, non-poisonous solution offers exceptional solubility in water, ensuring rapid dispersion and consistent results for both large-scale and small-scale projects.

Reliable and Safe Construction Solutions

With a chloride content below 0.1% and air entrainment under 2.0%, our SNF admixture is engineered for reliable, safe performance in all types of concrete mixes. It meets industrial-grade purity standards and comes with a 12-month shelf life when stored in ideal conditions. The product is supplied in robust plastic drums, IBC tanks, or flexitanks to suit your supply chain needs, making storage and handling convenient and secure.

FAQs of Chemical Admixtures:

Q: How should Sodium Naphthalene Sulphonate Formaldehyde be stored to maintain its quality?

A: It should be kept in cool, dry, and well-ventilated places, away from direct sunlight or heat sources. Properly stored, the admixture retains its efficacy for up to 12 months.

Q: What is the recommended process for adding this admixture to a concrete mix?

A: The admixture can be added directly to the mixing water or introduced separately into the concrete mix. For optimal effects, ensure it is compatible by adding it separately from other admixtures.

Q: When should this water reducing admixture be used in concrete production?

A: It is ideally used during the batching processprior to or at the start of mixing. Early addition guarantees thorough dispersion and maximizes water reduction and strength development benefits.

Q: Where is this product commonly applied in the construction industry?

A: This admixture is widely used in ready-mix concrete plants, precast concrete manufacturing, and general concrete construction where enhanced workability and early strength are required.

Q: What dosage of this admixture is recommended for best results?

A: A typical dosage ranges from 0.5% to 1.5% by weight of cement, depending on the required performance and specific site conditions. Always conduct a trial before mass application.

Q: How does this admixture benefit concrete performance?

A: It offers high water reduction, excellent dispersing effect, and accelerates early strength gain, resulting in improved workability, durability, and overall quality of concrete structures.
