It is a High Range Water Reducing Superplasticizer (based on SNF, sulphonated naphthalene formaldehyde condensate (SNF), available in liquid form. Admix SNF produces high workability concrete requiring little or no vibration during placement. Admix SNF provides up to 25% reduction in free water without loss of workability, resulting in high-quality concrete of reduced permeability and increased early strength gain
