concrete admixtures SNF Construction Real Estate

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.

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.
