Description
concrete super plasticizer-fast harden
concrete super plasticizer-fast harden is a liquid additive based on polynaphthalene sulfonate, which, in addition to the fluidity of concrete and the strong reduction of the amount of water consumed by concrete, causes faster setting time and increases the initial and final strengths in a shorter time. It also compensates for the negative effects of retardation at low temperature.

Product Description – Fast-setting concrete superplasticizer
Fast-setting concrete superplasticizer is a liquid additive based on polynaphthalene sulfonate, which in addition to the fluidity of concrete and a strong reduction in the amount of water consumed in concrete, accelerates the setting time and increases the initial and final stability in a shorter time and also compensates for the negative effects of setting delay at low temperatures. This concrete superplasticizer is specifically designed for concreting and achieving desirable initial strengths in cold weather conditions. Fast-setting superplasticizer, in addition to significantly reducing the water consumed in concrete, accelerates the setting of concrete and the rate of hydration of water into cement, which makes concrete superplasticizers a priority for use compared to other types of concrete antifreeze for concreting in winter and cold and severe weather conditions. Also, the use of fast-setting superplasticizers creates the ability to reduce water by about 10 to 15 percent.
Superplasticizer is a type of high-range water reducer used in concrete. Concrete superplasticizer can create denser and more durable concrete. Fast-setting concrete superplasticizer can transform stiff, low-slump concrete into a smooth, pourable mortar, improve concrete workability, increase setting speed, and can also increase strength and reduce shrinkage and thermal cracking.

Consumption rate of superplasticizer for quick-setting concrete
What is the standard amount of superplasticizer used for quick-setting concrete?
The exact amount of superplasticizer additive for fast-setting concrete is determined by conducting proper site tests, weather conditions, and the type of materials used. The best consumption range for this product is between 1 and 1.5 percent of the weight of cement used in concrete. Excessive consumption of the product is not permitted, and it is recommended that you seek advice from experts at Beton Plast Chemical Company if necessary. Excessive consumption will further accelerate the setting of the concrete, in which case the concrete will not reach its ideal conditions in terms of strength and other properties.
Price of superplasticizer for quick-setting concrete?
It is strongly recommended that you never base your purchase on the cheap price of a fast-setting concrete superplasticizer . Because you may get a fast-setting superplasticizer at a cheap price, but it may not be suitable in terms of performance, or due to the low concentration of the raw materials that make up the product, we will have to mix a larger amount in the concrete, which means that by adding more than the permitted amount of additive, more water will naturally enter the concrete, which can cause major weaknesses in terms of strength for the concrete mixture. It should also be noted that if a fast-setting concrete superplasticizer is added at a high dosage, more pre-setting materials will unintentionally enter the concrete, which can be a serious threat to the setting and hydration time of the concrete. It is also recommended that when purchasing this product, make sure that no destructive acids have been used to speed up the setting of this product.

How to use superplasticizer for quick-setting concrete
What is the correct way to use superplasticizer for quick-setting concrete?
- The amount of superplasticizer for quick-setting concrete calculated according to the grade of concrete should be diluted with 2 times the volume of concrete mixing water. The diluted admixture should be gradually added to the concrete during mixing.
- This product can be added to the ready-mixed concrete and after complete mixing, concreting can be done. It is recommended to mix for at least 1 minute per cubic meter of concrete.
- Fast-setting concrete superplasticizer can be added to the batching or truck mixer during concrete production.
Be careful not to pour the superplasticizer additive for quick-setting concrete directly onto dry cement.

Mechanism of action of superplasticizers in fast-setting concrete
What is the result of the effect of the superplasticizer product for fast-setting concrete in improving the performance of concrete?
When mixing water and cement, the molecules of the fast-setting concrete superplasticizer based on polynaphthalene sulfonate create a charged density around the cement particles, which prevents the cement grains in the concrete mixture from moving towards each other, thus making the concrete fluid. Naphthalene sulfonate also prevents the dissolution of ions such as aluminates, which have the highest dissolution rate during the hydration process. In addition, in the formulation of the fast-setting concrete superplasticizer, substances are used that accelerate the hydration rate of the cement.
How to identify a quality fast-setting superplasticizer additive?
The superplasticizer for rapid-setting concrete should have a density similar to oil, which can be easily detected by touching it with your fingers. Also, this additive should not have any settling or suspended particles in its structure. In terms of appearance, the superplasticizer for rapid-setting concrete should be dark brown in color and have a uniform and homogeneous appearance. Note that in terms of performance, the superplasticizer for rapid-setting concrete should be in accordance with the recommended amount in the manufacturer’s catalog and also in accordance with the standard consumption rate of the product. Note that the superplasticizer for rapid-setting concrete should have a controlled rate of rapid setting by the manufacturer.
