Power SNF concrete admixture

Product Description

SNF-5A Sodium Naphthalene Sulfonate Formaldehyde Concrete Agent has the characteristics of retarding, super-plasticized, water-reducing, less loss of slump. It is very effective concrete admixture to adopt in high temperature area. concrete admixture

Main Properties and Characteristics

1 .Excellent effect of retarding: It can be used in retarding the setting of concrete for 2 hours to 36hours, and initial setting and ultimate hardening almost happen at the same time, so that it’s convenient for conveying at long distance.

2 .With the water-reducing rate of 15%-25%, it can improve the flowability, permeation-proofing ability, and the workability of concrete, concrete compression resistant, and other physical mechanics will be also gained.

3 .Reduces cement dosage by 15%-25% without altering compression strength and slump.

4. Good for many applications: Portland cement, ordinary Portland cement, Portland fly-ash cement, Portland pozzolana cement and Portland blast furnace-slag cement. retarder concrete admixture

Standards

SNF-5A has been formulated to comply with BS5075 for high range water-reducing admixtures,GB8076-1997, ASTM C494 and Chinese Standard’s Cement(P.O.42.5).

Typical performance

SNF-5A improves initial and ultimate strengths. It also gets less loss of slump and improves

workability of the concrete more than traditional superplasticizer. The lower content of Na2SO4, in the admixture, will lead to meet the requirement of the special cement concrete engineering project in the coastland andhigh saline-alkali area.

Application Method

1. SNF-5A is applying steel reinforcement concrete and in the condition of normal temperature.

2. SNF-5A is applying prestressed concrete in the condition of normal temperature

3. It can get good quality flowable plasticizied concrete , retarder concrete admixture

4. It can get less loss of slump, high strength, high flexible modulus, excellent permeation-proofing ability, low shrinkage and outstanding resistance concrete.

Dosage

In order to meet specific requirements, SNF-5A addition rate should be determined by the materials and the conditions of the experiments and the water-reducing request. The scope of the SNF-5A Powder addition rate is from 0.4kg-1.5kg per 100kg cement materials.
