Description
The BC 102N product is the first generation of admixtures in the group of lubricants. This material disperses the fine particles in the concrete mixture and causes the water in the mixture to act more effectively.
This material can provide water reducing and super-reducing properties depending on the amount used.
Applications
Increasing the workability time of concrete
Ready-mix concrete
Vascular concrete such as dam bodies and foundations
Large beams and bridge decks, etc.
Where reducing vibration prevents the occurrence of construction joints.
High reinforcement density and increasing the adhesion of materials in concretes that do not have proper grain size.
Concrete pouring using a pump
Increasing and adjusting concrete efficiency in batching
Features and benefits
Improving concrete durability
Increasing concrete slump or efficiency
Increasing concrete workability
Ease of pumping and reducing equipment wear and tear
Reducing water-to-cement ratio by about 5% to 12%
Increasing concrete consistency
Reducing concrete permeability
Compatibility with various types of Portland cement and pozzolanic materials
Preventing concrete creep and shrinkage
Achieving smooth and uniform surfaces for exposed or attractive concrete
How to use
The consumption rate is between 0.5 and 1.5% by weight of the cement used (half a percent to one and a half percent for 100 kg of cement), and the definitive consumption rate should be obtained by workshop tests, depending on different weather conditions and the type of sand, gravel, and cement used.
Superplasticizer 102N is a ready-to-use additive and should be added at the time of concrete production. Its best effect is when about 50 to 70 percent of the concrete water is added. Never add this product to dry materials. Stir the mixture with a high speed for 60 seconds to mix thoroughly.
Neutral Lubricant and Water Reducer
Neutral lubricant is one of the most important concrete additives that plays a very important role in improving the properties of concrete. In the following, we will fully examine this additive, its applications, benefits and types.
What is a neutral lubricant?
A neutral lubricant is a liquid chemical that is added to the concrete mixture to increase the workability of concrete. This substance makes the concrete more fluid and workable by reducing the surface tension between cement particles and water. As a result, concrete with more fluidity can be produced with less water.
Benefits of using neutral lubricant:
Increase concrete efficiency: Neutral lubricant makes concrete easier to pump, better spread in molds, and as a result, higher quality concrete is poured.
Reduce water-cement ratio: By using this additive, the amount of water used in concrete can be reduced, which leads to increased compressive strength, durability, and stability of concrete.
Reduce segregation and water loss: Neutral lubricant reduces aggregate segregation and water loss of concrete, which leads to improved concrete surface quality.
Increase concrete strength: By reducing the water-cement ratio, the compressive, flexural, and tensile strength of concrete increases.
Reduce concrete permeability: Concrete produced using neutral lubricant has less permeability and is more resistant to water and harmful ions.
Types of Neutral Lubricants:
Neutral lubricants are divided into different categories based on the type of active ingredient used in them, including the following:
Naphthalene sulfonate-based lubricants: These types of lubricants are the most widely used type of neutral lubricants and have high water-reducing properties and a good effect on concrete performance.
Melamine sulfonate-based lubricants: These lubricants have the property of maintaining fluidity at high temperatures and are suitable for pouring concrete in hot weather.
Polycarboxylate-based lubricants: These lubricants are a new generation of lubricants that have very high performance and a long-term effect on concrete.
Neutral lubricant applications:
Production of high-strength concrete: Using neutral lubricants, concrete with high compressive strength and durability can be produced.
Production of self-compacting concrete (SCC): These lubricants play an important role in the production of self-compacting concrete that does not require vibration.
Production of pumpable concrete: Using neutral lubricants, high-flow concretes can be produced that are easily pumped.
Production of concrete with complex mixing patterns: These lubricants are used in the production of concrete with complex mixing patterns that contain various additives.
