Product Description – Carboxylated Concrete Super Lubricant
Superplasticizer is a liquid additive based on polycarboxylate ether. Concrete superplasticizer is a very strong reducer of concrete mix water and is a very strong enhancer of high-performance concrete and significantly improves the dispersion of cement particles. The use of this product is strongly emphasized for the requirements of making special concrete (self-leveling and self-compacting) and concretes whose regulatory requirements are to minimize the water-to-cement ratio or in special conditions where the slump loss cannot be compensated with other superplasticizers. Due to the significant reduction in the water-to-cement ratio, carboxylate superplasticizer increases the resistance and reduces the permeability of concrete against the penetration of destructive chemicals and consequently increases the durability and strength of concrete. Its use also reduces the water-to-cement ratio by about 30 percent.
A lubricant is a liquid admixture. A cement lubricant significantly reduces the amount of water required to mix concrete, increasing the performance or workability of the concrete. It also increases the compressive strength of concrete at an early age. Lubricant products are divided into three categories; super-lubricants, fast-setting super-lubricants, and slow-setting super-lubricants, each of which is used in its own specific climate.
Concrete admixtures are additives that can increase the fluidity of concrete without increasing the amount of water in it. Using concrete admixtures makes concrete smoother and easier to place and compact. Concrete structures that require high-quality, high-performance concrete also use this additive.

Usage rate of carboxylated concrete superplasticizer
What is the standard usage rate of carboxylated concrete superplasticizer?
The best amount of consumption to achieve specific properties is determined by conducting various tests in workshop conditions, which depends on various factors including ambient temperature, type and size of aggregates, cement grade, water to cement ratio, etc. However, the normal amount of superplasticizer consumption is usually 0.2 to 0.8 percent of the weight of the cement used.

How to use carboxylated concrete superplasticizer
What is the standard consumption rate of carboxylated concrete superplasticizer?
1 – Dilute the amount of superplasticizer calculated according to the grade of concrete with twice the volume of concrete mixing water. Add the diluted admixture gradually to the concrete during mixing.
2 – This product can be added to the ready-mixed concrete and after complete mixing, concrete can be placed. It is recommended to mix for at least one minute per cubic meter of concrete.
3 – Carboxylate superplasticizer can be added to the batching or truck mixer during concrete production.
Don’t: Be careful not to pour the carboxylate superplasticizer additive directly onto dry cement.

Mechanism of action of carboxylated concrete superplasticizer
What is the mechanism of action of the carboxylated concrete superplasticizer product?
The shape of the molecules that make up the polycarboxylate ether-based plasticizer consists of a main branch and several sub-branches. By adding polycarboxylate ether to the concrete mixture or cement mortar, a charged layer consisting of polycarboxylate ether molecules fills the area around the cement grains. This causes the cement particles to move away from each other inside the concrete mixture or mortar. In principle, the spatial separation of the sub-branches of the polycarboxylate ether material causes the particles to be repelled, and the hydrophobic force in the main branch of this material causes the large molecules to be attracted by the cement particles, thus placing the water molecules at a greater distance from the cement particles in the mixture. This property causes the flowability of the concrete mixture or mortar. After a certain time, the charges created in the concrete mixture are destroyed by reverse induction, causing the concrete slump to decrease and the cement hydration to begin, and the concrete and mortar setting process to begin.
How to recognize a quality carboxylate superplasticizer?
Polycarboxylate ether-based concrete superplasticizers are usually produced and presented in a clear or light honey color. The first option in quality control of carboxylate ether superplasticizers is to control the color of the product. If the color of the purchased product is dark brown, it is likely that materials other than polycarboxylate ether were used to produce this product and the superplasticizer definitely lacks carboxylate superplasticizer properties. Another control point is to control the concentration of the additive by touching it with your fingers. A quality carboxylate superplasticizer with standard performance has an oil-like consistency. Another important point in this regard is the integrity and uniformity of the polycarboxylate ether-based superplasticizer additive. This material should not have any settling particles and should be completely uniform.
Safety of carboxylated concrete superplasticizer
What are the safety conditions when using carboxylated concrete superplasticizer?
Safety principles of carboxylated concrete superplasticizer;
- This material is not toxic, dangerous, or flammable.
- This product should never come into contact with the eyes. If it does come into contact with the eyes, rinse immediately with plenty of water.
- If skin sensitivity occurs, see a doctor.
