Concrete Superplasticizer PRH-80

گالن 20 - 220 - 1000 لیتری

PRH-80 Concrete Superplasticizer is one of the most effective concrete-enhancing additives, formulated based on polycarboxylate ether. Due to its unique physical and chemical properties, it significantly improves concrete performance and reduces the amount of water required in the mix. Similar to PC100N Concrete Superplasticizer—also based on polycarboxylate ether—PRH-80 is used to enhance concrete performance and reduce water consumption in the mix. By increasing workability, this additive improves mechanical strength, durability, and impermeability of concrete, playing a vital role in the quality of concrete structures. It provides optimal plasticity and flow, enabling the production of high-performance concrete, especially in civil engineering projects such as columns, shear walls, bridge construction, and more.

Mechanism of Action of PRH80 Concrete Superplasticizer Polycarboxylate ether is a type of concrete superplasticizer additive used in the production of ready-mix concrete, self-compacting concrete (SCC), ultra-high-performance concrete (UHPC), and more. It significantly reduces water content and enhances concrete strength. To identify a high-quality polycarboxylate superplasticizer, the first step is to check the product’s color. If it’s dark brown, it likely contains substances other than polycarboxylate ether and won’t exhibit true superplasticizer properties. Additionally, the additive’s viscosity can be assessed by touch. A quality polycarboxylate superplasticizer should have an oil-like, uniform consistency with no sediment. These characteristics define the superior PRH-80 concrete superplasticizer, which improves concrete strength and durability.

Dosage Range of PRH80 Concrete Superplasticizer

Recommended dosage: 0.2% to 0.9% of cement weight, based on manufacturer testing and experience.
Multiple tests under varying conditions (temperature, material types, cement-water ratios) are advised for accurate dosage.
Environmental factors like temperature and humidity may affect dosage, so real-site testing is crucial.
Dosage should be adjusted based on desired concrete properties such as compressive strength, workability, and setting time.
Manufacturer specifications and instructions must be followed for optimal use.

Standard use of this additive not only enhances concrete properties but also offers economic benefits by reducing cement consumption and improving workability and pumpability.

Method of Application for PRH80 Concrete Superplasticizer

Dilution Method: If using dilution, gradually add the superplasticizer to the mixing water, then incorporate the mixture into the concrete to ensure even distribution.
Addition to Ready-Mix: When adding to a prepared mix, ensure the superplasticizer is evenly dispersed to maintain consistent effects on concrete properties.
Addition via Batching or Truck Mixer: This method is also effective, but care must be taken to mix the superplasticizer thoroughly with other materials.

In all cases, avoid pouring the superplasticizer directly onto dry cement. Proper mixing and blending procedures must be followed carefully to achieve optimal results.
