Factory Naphthalene Formaldehyde Superplasticizer Snf High Water Reducer

Product Description

Product Overview

A high-performance water reducer in the plasticizer category, the naphthalene-based variant is an anionic surfactant made from industrial naphthalene via chemical processes like sulfonation, condensation, and neutralization. Its key component, naphthalene sulfonate formaldehyde condensate, makes it one of the most prevalent concrete admixtures.

Key Features

High Water Reduction
Water reduction rate: 15%~25%, significantly lowering the water-cement ratio and enhancing concrete strength.
Strength Enhancement
Increases compressive strength by 20%~40%, with notable early-stage strength development.
Improved Workability
Enhances concrete fluidity, facilitating pumping and placement.
Retarding Effect
Extends initial setting time by 1~3 hours (varies with dosage), beneficial for summer construction.
Low Air Entrainment
Air content typically <3%, ensuring no adverse impact on concrete durability.
Broad Compatibility
Compatible with most cement types, though trial tests are recommended for certain mineral admixtures (e.g., flyash).
 

Application Scope of Naphthalene-based Water Reducer

Construction Projects: Cast-in-place concrete, precast components
Infrastructure Projects: Roads, bridges, tunnels, water conservancy
Special Concrete: High-strength (C50+), pumping, mass concrete
Precast Elements: Pipe piles, sleepers, segments
Special Construction: High-temperature environments, long-distance transportation

Method of use

When it is powder,mix well of cement sand and stone then put in water last step in admixture is better.
When it is liquid,put admixture in last step is best one.

Packaging and shipping

Powder package by plastic bag lined or woven inside,paper bag net weight 25/40kg,liquid used plastic barrel,metal barrel,net weight 200kg,1000kg.also can be used transport tankers in bulk transport tanker.Transport should prevent moisture,the dram should prevent leakage or evaportation drying.
