Water Reducer CA Lignosulfonate Concrete Admixture CAS 8061-52-7

Calcium Lignosulphonate Use As Concrete Water Reducer Cas 8061-52-7

Calcium lignonate in construction as a flame retardant super plasticizer, is an anionic surface active substance, the adsorption of cement and disperse concrete can improve a variety of physical properties. Reusable formulation of early strength agents, retarders, antifreeze, pumping agents and naphthalene superplasticizers, made from a liquid mixture, virtually precipitation-free.

Main feature

1. Mass sulfonate super plasticizer dosage cement content 0.20-0.30%, common dosage is 0.25%, water reduction can reach 9-11%. At the appropriate dose, the long-term strength was also improved by 15-20% compared with the reference coagulated 10 strength for 3 days, 20-30% for 7 days and 15-20% for 28 days.

2. Do not change the water in the case of coagulation (the recommended ratio is 0.65) to increase the fluidity of coagulation and improve the working ability.

3. In keeping the slump of concrete, the same strength and reference coagulation 10, cement can save 8-10%, using 1 ton of lentisulfonate superplasticizer powder, can save 30-40 tons of cement.

4. Under the standard state, the setting time of concrete and coagulants may be delayed for more than 3 hours, and the final setting time is 3 hours. The hydration heat peak delay time is more than 5 hours, which is conducive to thousands of summer construction and commodity coagulation ten transportation and mass coagulation ten.

5. And a trace of entrained lignosulfonate superplasticizer, can improve the coagulation-freeze-thaw properties of the impermeability.

The effects of Calcium Lignosulfonate on the properties of concrete mix are shown in the following aspects:

①. Due to the adsorption, dispersion, electrical property, surface free energy reduction of calcium lignesulfonic acid and other effects, so that the free water in the flocculation structure of the water released, the electrical repulsion between the cement particles, hydration film lubrication, the lubrication effect of bubbles to increase the rheological properties of cement slurry, thus improving the working ability of concrete, using the same amount of water slump increase.

②.The water consumption of mixing can be reduced by 8% under the condition of maintaining the same slump.

③ It can maintain the plasticity of concrete for a long time and reduce the slump loss from mixing to pouring. When the standard dosage is used, the initial and final setting time of ordinary Portland cement can be delayed by 1~2h, and the slag Portland cement can be delayed by 2~4h and 2~3h, respectively.

④ The adsorption film formed by the surface adsorption of calcium lignosulfonate hindered the initial hydration reaction, controlled the rate of hydration heat release, and reduced the height of the peak hydration heat, which could inhibit the large volume

Cracks in concrete and dam concrete caused by hydration and heat release.

⑤ The adsorption of calcium lignosulfonate, air lifting, electrical repulsive force and other effects, so that the settlement of bone particles in concrete slowed down, in the solidification and hardening before maintaining a stable state of suspension, thereby reducing the glendening of concrete and settlement.
