Polycarboxylates

Polycarboxylates are linear polymers with a high molecular mass (Mr ≤ 100 000) and with many carboxylate groups.
They are polymers of acrylic acid or copolymers of acrylic acid and maleic acid. The polymer is used as the sodium salt (see: sodium polyacrylate).

What is the concrete plasticizer?

Plasticizers are the largest additives in the modern plastics industry and play a decisive role in promoting the development of the plastics industry, especially the PVC industry.
Anything that can be uniformly mixed with resin without chemical change during mixing, but can reduce the glass transition temperature of the material and the melt viscosity during plastic molding processing

Cement plasticizer

Mortar plasticizers have been used in China in the 1960s. However, due to the restrictions of construction specifications
the research on mortar plasticizers is not thorough and systematic, and there is no consensus on some issues.

Cement admixtures

Cement process admixtures refer to the addition of a certain type and amount of admixtures during the production and production of cement under the conditions of greening, environmental protection and energy saving.
Generally, the addition amount of admixtures should be controlled within 5%. Improve and optimize the performance of cement materials to achieve a process technology that reduces production costs.

Do superplasticizer admixtures affect the strength of concrete?

Because of the different types of concrete additives, the effects are also different. The general function is to improve the fluidity of the corresponding concrete when the water consumption per cubic meter of concrete or the cement consumption does not change
when the cement consumption remains the same or the concrete slump remains unchanged, the water consumption can be achieved.

Concrete water reducer

Water reducer is a specifically designed polycarboxylate superplasticizer which owns excellent dispersion performance while maintaining good retention effects due to our cutting-edge processing technique
it is used as a high range water reducing admixture in high performance concrete,high strength concrete

Cement additives

Cement additives refer to additives added to improve or realize various characteristics in the process of cement application
such as quick-drying or enhancement, such as water reducing agents, and reducing water content, such as retarders.

Admixture dosage in concrete?

Water reducer

Concrete admixture is a chemical substance mixed in the process of making concrete, which can improve the performance of concrete.
The amount of admixture in concrete is small (not more than 5%) but indispensable. Water reducer is the mainstream of admixtures.
In 2017, it accounted for 66.61% of the total output of concrete admixtures.
