Sodium Lignosulphonate Powder

Sodium lignosulfonate (lignosulfonic acid, sodium salt) is used in the food industry as a de-foaming agent for paper production and in adhesives for items that come in contact with food. It has preservative properties, and is used as an ingredient in animal feeds.

Sodium lignosulfonate used as plasticizer in concrete will reduce the cost by 10-15%,the sodium lignosulfonate could assume 0.5-2% of the total mixture w/w,will increase the strength of concrete by 20-26%.

Sodium Lignosulfonate plasticizer Functions as follows

Improved strength and durability of the cured concrete
Reduced formulation cost
Increased workability of the concrete mix

Sodium lignosulfonate uses water reducing agent, By sulfite pulp waste liquid of legal system formed by chemical modification and processing. Medium molecular weight, The reducing sugar content in low,Used for concrete admixture, With low dosage, low gas content, to cement the characteristics of strong adaptability, The most notable feature is the rear with naphthalene superplasticizer complex, Liquid admixture made no precipitate.

Main performance

Can reduce water consumption by more than 14%, Significantly improve the workability of concrete. Can greatly reduce the initial heat of hydration of cement hydration. No chlorine salt, no corrosive effect on steel. Alkali-free active substance.

1.Sodium Lignosulfonate uses as superplasticizer dosage of cement content 0.20-0.30%, commonly used dosage is 0.25% water reduction of up to 9-11%. In the appropriate dosage when compared with the reference concrete strength increased by 15-20% 3 days, 7 days strength increased 20-30%, 28 days by 15-20%, long-term strength also increased.

2.Without changing the water in the case of concrete( suggested ratio 0.65)1to increase the flow of concrete, improved work-ability.

3.In keeping concrete slump, the same intensity and the reference concrete, cement can save 8-10%, the use of one ton of  Lignosulfonate superplasticizer powder, can save 30-40 tons of cement.

Method of use

Sodium lignosulfonate uses as water reducing agent,In concrete recommended dosage of 0.2% -0.6%(cement weight meter), Users should determine the optimal dosage through the experiment. Sodium lignosulfonate water reducing agent can be used as liquid. Users can experiment to determine the content and proportion.

Micronised Biomass Silica (MBS) is an agricultural waste product which comprises of high content of silica. This study was conducted on the off-white amorphous biomass silica ash derived from the rice husk with pozzolanic index 69%. Various percentages of MBS ranging from 0% to 20% by mass have been used as cement replacement material. Compressive strength and water permeability of concrete with MBS incorporation were investigated.

Sodium hydroxide (NaOH) is an inorganic compound. It is a white solid and highly caustic metallic base and alkali salt of sodium which is available in pellets, flakes, granules, and as prepared solutions at a number of different concentrations. Sodium hydroxide forms an approximately 50% (by weight) saturated solution with water. Sodium hydroxide is soluble in water, ethanol, and methanol. This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air. Sodium hydroxide is used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, soaps, detergents and as a drain cleaner. It is also used in concrete in the construction industry.

In this application, free-flowing perlite loose-fill masonry insulation is poureMasonry Tools Perlited into the cavities of concrete block where it completely fills all cores, crevices, mortar areas and ear holes. In addition to providing thermal insulation, perlite enhances fire ratings, reduces noise transmission and it is rot, vermin and termite resistant. Perlite is also ideal for insulating low temperature and cryogenic vessels. When perlite is used as an aggregate in concrete, a lightweight, fire resistant, insulating concrete is produced that is ideal for roof decks and other applications. Perlite can also be used as an aggregate in Portland cement and gypsum plasters for exterior applications and. for the fire protection of beams and columns. Other construction applications include under-floor insulation, chimney linings, paint texturing, gypsum boards, ceiling tiles and roof insulation boards.
