Sodium Lignosulfonate Concrete Agent,water-reducing admixture - COST-SL

Sodium Lignosulfonate Concrete Agent

Product Description

Lignin sulfonate is a natural chemical modification of lignin products whose state is brown fine powder with slightly aromatic odor, and non-toxi, harmless.

It is a product through chemical processing which is black liquid waste discharged from paper making using wheat straw, rice straw, straw, reeds, sugar cane and other plants as raw material.

This product is especially suitable for hot climates cement concrete mixing station.

The lignin sulfonate used as concrete admixtures with the feature of mixed with less water-reducing rate, low gas content, good workability, inexpensive, easy-to-use, which is a good nature superplasticizer.

The aqueous solution does not occur the precipitation when mixed with the naphthalene-based, melamine resins.

The products cost performance is ideal. If use reasonablely, it can reduce costs and increase economic benefits significantly .

Product Properties

1, Less water is in 8-12%. The products can save 8% -12% of cement in the same slump and conditions of the same strength.

2, Improving the workability of the concrete significantly.

3, It can extend the initial setting time of 2.5 hours, 3 hours of the final setting time.And the heat of hydration peak can be postponed for more than five hours in the standard state which is convinent to the summer construction and commercial concrete, mass concretetransport.

4, No chlorine ions, no corrosion to steel hazards.

5, It applys for all kinds of various reinforced concrete compounded with portland cement formulated the conservation of the natural room temperature and prestressed concrete.

6, The 3 - 28 days compressive strength can be increased by 15% on average when use the product.

Product Feature

Consistency

This product is compatible with other cement concrete admixtures, but must be blending saprately.

If the hybrid mixing ,it must be first tesed to identify and to avoid non-predictable retardation.

It is applicable to ordinary Portland cement and cement substitutes, such as cement, fly ash, granulated blast furnace slag and silica fume etc.

Application Methods

1, when use the product, incorporation ineffective must be strictly controlled. On one hand the effect is not obvious with little incorporation. On the other hand it will affect the early strength with more incorporation. So it must be adjusted by test incorporation.

As the starting point for the test with a typical dosage range of 0.25-0.5 kg / 100 kg of cementitious materials (including cement, fly ash, granulated blast furnace slag powder and silica fume, etc).

2, The powder can be reused dubbed a certain concentration of liquid added as the form of the liquid, but it shoud be attented the water content should be deduction from the total amount of water in the concrete superplasticizer solution.

3, The powder can be added to the mixer and cement, aggregate (sand and gravel) dry mix evenly then add water and stir, but need to be appropriate to extend the mixing time.

4, Effect is obviousely when mixed with naphthalene superplasticizer. Compounded dosage ratio can make sure after experiment. Users can be based on the type of cement, aggregate situation, naphthalene superplasticizer varieties comprehensive consideration.

Storage and Transportation
