Super lubricant and strong water reducer، It is a type of concrete additive that is used to increase the fluidity and efficiency of concrete and also to reduce the ratio of water to cement in the concrete mix. This chemical substance helps the concrete to flow better by dispersing the cement particles and creating air bubbles in the concrete mixture.
Advantages of using super lubricant and strong water reducer
Increasing the flow of concrete: This makes the concrete easily poured into the mold and penetrates into the corners and sides of the mold.
Reducing the ratio of water to cement: This leads to an increase in the strength, durability and impermeability of concrete.
Reducing the ratio of water to cement: This leads to an increase in the strength, durability and impermeability of concrete.
Reduction of air voids: This makes the concrete denser and more resistant to frost and corrosion.
Increasing the pumpability of concrete: This makes it easy to move the concrete to the desired location using the pump.
Reducing concrete setting time: This can be useful in some cases, especially in situations where rapid molding of concrete is required.
Applications of super lubricant and strong water reducer
Concreting in hot weather: In hot weather, concrete tends to harden quickly. The use of super-lubricant and strong water reducer can help to maintain the fluidity of concrete in these conditions.
Concreting in complex forms: In complex molds, the concrete should easily penetrate all the corners and sides of the mold. Using super lubricant and strong water reducer can help with this.
High strength concrete production:To produce concrete with high strength, a low water-cement ratio should be used. The use of super-lubricant and strong water reducer can help maintain the performance of concrete in these conditions.
High volume concreting: In massive concreting, the fluidity of the concrete must be ensured to prevent its premature setting. Using super lubricant and strong water reducer can help with this.
All kinds of super lubricants and strong water reducers
Super lubricants and strong water reducers are produced in different types, each of which has its own characteristics and applications. In general, these materials are divided into two main categories:
Super lubricants based on petroleum: These types of superlubricants are cheaper, but may create air bubbles in the concrete.
Super lubricants based on polycarboxylate: These types of super lubricants are more expensive, but they do not create air bubbles in concrete and are more efficient.
How to use super lubricant and strong water reducer
How to use super lubricant and strong water reducer depends on its type and manufacturer’s instructions. In general, this material should be added to the concrete mixture in the final stages of mixing and thoroughly mixed with the concrete.
safety tips
- Super lubricant and strong water reducer may cause skin and eye irritation.
- Gloves, goggles and a mask should be used when using this material.
- This material should be kept out of the reach of children.
The negative consequences of not using super-lubricant and strong concrete water reducer
Not using it can have several negative consequences, some of which are:
Reducing the efficiency of concrete:
More difficult to mix: Concrete becomes more difficult to mix due to the greater adhesion of cement particles and aggregates. This increases the need for more force to mix and compact the concrete and can lead to inhomogeneity in the final mix.
Reducing the strength of concrete:
Cracking: Increasing the water-cement ratio can also lead to an increased risk of concrete cracking due to drying and shrinkage.
Increased permeability:
More pores: reducing the ratio of water to cement and increasing the voids in concrete can lead to an increase in its permeability. This makes the concrete more vulnerable to water intrusion, harmful chemicals and chloride ions that can corrode the rebar.
Increased costs:
More work: Difficulty working with harder, less fluid concrete can lead to increased labor time and cost.
More maintenance: Reduced strength and durability of concrete can lead to the need for more maintenance in the future, which will result in additional costs.
Conclusion
A super-lubricant and powerful water reducer is a useful concrete admixture that can bring many benefits to your concreting projects. By using this material, you can increase the fluidity, efficiency, resistance and durability of concrete.
