Sodium Lignosulfonate is a superplasticizer and retarding agent with anionic properties, used frequently in construction. It is a surface-active substance that works efficiently on the dispersion and adsorption of cement. Sodium Lignosulfonate also improves concrete’s physical performance, thus ensuring that it makes the building or house long-lasting. The element uses a water reducing agent to chemically process and modify concrete and cement.
Using Sodium Lignosulfonate in low doses and low gas conditions can increase cement’s adaptability. Additionally, the element mixes with naphthalene superplasticizer to prevent any precipitation.
Features of Sodium Lignosulfonate
Some of the crucial features that make sodium lignosulfonate uses in construction essential are as follows:
• A dosage of 0.20 to 0.30% of Sodium Lignosulfonate can increase concrete’s strength by almost 15 to 20% within three days. If you keep it longer, it can improve its strength by almost 30%. However, the strength starts to deteriorate if you don’t use the concrete within seven days. Therefore, construction companies should mix Sodium Lignosulfonate with concrete for five to seven days to achieve better strength.
• Sodium Lignosulfonate can also increase concrete’ workability by preventing water from changing its structure. You also need to make sure that you don’t use too much water in the process. Experts suggest that it’s best to keep a ratio of 1:0.65 to achieve the ideal workability.
• Cement can save approximately 8 to 10% if it uses the same intensity as concrete. But mixing Sodium Lignosulfonate can save nearly 30 to 40 tons of cement.
• Mixing Sodium Lignosulfonate with concrete may delay concrete’s setting time by over 3 hours. It can also delay its hydration process by five hours or more. This makes sodium lignosulfonate essential to make high-quality concrete that can make long-lasting buildings and houses.
• Sodium Lignosulfonate has micro-entraining properties that improve concrete’s impermeability and freeze-thaw performance.
Uses of Sodium Lignosulfonate in Construction
The sodium lignosulfonate uses in construction are not direct. You need to mix the agent with concrete and cement to get the desired results. In addition to construction, the agent also finds its way into various other projects, such as pumping concrete, high-fluidity concrete, and concrete construction.
One of the reasons why people are lauding sodium lignosulfonate uses in construction is because it can bring down concrete’s water consumption by as much as 14%, thus significantly improving its workability.
Some of sodium lignosulfonate uses in construction that makes a difference in the quality of cement and concrete are as follows:
• Cement hydration is a long process and requires sodium lignosulfonate as its primary hydrating agent. This agent can significantly reduce cement’s initiate hydration heat, thus improving its quality.
• Sodium lignosulfonate works as a concrete superplasticizer that reduces water usage. Additionally, it can also increase the strength of cement and concrete over time. You should wait for at least 5 to 7 days before using the concrete and cement with which you mixed Sodium Lignosulfonate.
• The flow of concrete is also an essential factor that determines the overall construction productivity. Thanks to sodium lignosulfonate, concrete has a higher flow rate, but you need to use water in appropriate amounts to maintain the flow.
Using Sodium Lignosulfonate
The sodium lignosulfonate used in construction starts when you mix the agent directly with gravel, sand, and cement. Add water in the ratio of 1:0.65 to ensure that the cement and concrete can improves their compressive strength over time. Let the mixture settle down for seven days before using it in construction projects.
Sodium lignosulfonate is a crucial agent that can improve the overall quality of cement and concrete. Mix it a few days before you start your next construction project. Please click this site https://kingsunconcreteadmixtures.com to get more information about sodium lignosulfonate.
