PRODUCT OVERVIEW
DESCRIPTION
Poly naphthalene sulfonate (PNS) is a high-range water reducer and dispersant used in concrete admixtures. It improves the workability and flowability of concrete mixtures while reducing the water content, leading to higher strength and durability. PNS is particularly effective in producing high-performance concrete for applications such as precast elements, bridges, and tunnels. It also helps in reducing shrinkage and improving the finish quality of concrete surfaces. PNS is compatible with other admixtures and is used in combination with superplasticizers and retarders to achieve desired concrete properties.
