Liquid form set retarders, known as LSR™, are ready-to-use additives used to delay the setting time of concrete. These liquid admixtures are particularly suitable for large-scale concrete projects as they reduce the rate of hydration. In addition to extending the setting time, LSR™ concrete additives have no impact on the final strength of the concrete.
The retarders in this category primarily consist of substances such as lignosulfates, sugars, hydroxycarboxylic acids, salts, and other organic compounds. They are commonly used with other additives like strength accelerators, water reducers, superplasticizers, humic acid groups, sulfonic acids, amino acids, and alkali metal salts, which enhance the fluidity of the concrete. Urea (carbamide) is recognized as an effective retarder, and lignosulfonate demonstrates retarding properties in concrete.

PRODUCT DESCRIPTION Liquid Form Set Retarding

When it comes to specific actions like massive concreting projects or concreting in tropical environments, optimizing the setting time of concrete becomes crucial for ensuring high-quality results. LSR™ liquid form set retarder is a reliable concrete additive designed to meet this need.
LSR™ is a ready-to-use liquid product that effectively prolongs the setting time of concrete. Reducing the hydration rate enables greater control over the concrete curing process without compromising the quality or strength of the final product. The use of LSR™ ensures that the concrete sets at a more desirable pace, accommodating the unique requirements of each project.

“When carrying out mass concreting in hot weather, controlling hydration is critical to prevent cold joints. Using a high-performance liquid concrete retarder such as LSR™ extends workability while ensuring long-term structural strength…”
LSR™ concrete retarder is formulated to comply with the ASTM C494 standard, ensuring its reliability and adherence to industry regulations. This liquid additive provides consistent performance and can be easily incorporated into concrete mixtures. With LSR™, you can confidently achieve the desired setting time for your concrete applications, ensuring optimal results in challenging conditions.
In addition to its setting time benefits, LSR™ offers several advantages for concrete production. Its liquid form allows easy handling and uniform dispersion throughout the concrete mixture, ensuring consistent retardation properties. The ready-to-use nature of LSR™ eliminates the need for additional complex mixing procedures, saving time and resources during the production process.
One of the key features of LSR™ is its ability to delay the setting time without compromising the overall strength and durability of the concrete. This ensures the final structure maintains its integrity and meets the required specifications. Whether for large-scale projects or applications in challenging environments, LSR™ provides the necessary control over the setting time to achieve optimal results.
Another noteworthy aspect of LSR™ is its compatibility with other concrete additives. It can be seamlessly integrated with various admixtures such as strength accelerators, water reducers, and superplasticizers. This versatility allows for customized concrete mix designs, enabling engineers and contractors to modify the concrete properties to meet specific project requirements.
Furthermore, using LSR™ can enhance the workability and pump ability of the concrete mixture, making it easier to handle and place. This can lead to improved productivity on construction sites and smoother concrete placement, reducing the risk of segregation or other issues that may compromise the quality of the structure.
In summary, LSR™ liquid form set retarder is a reliable and efficient solution for extending the setting time of concrete. Its ready-to-use nature, compliance with industry standards, compatibility with other additives, and ability to maintain concrete strength make it valuable for achieving optimal results in challenging concreting scenarios. Trust LSR™ to provide the control and flexibility you need for successful concrete production.

Application Instructions Liquid Form Set Retarding

Preparing the Concrete Mix:

Calculate the desired dosage of LSR™ based on the recommended dosage rate provided by the manufacturer.
Adjust the water-to-cement ratio if necessary to account for the retardation effect of LSR™ on the setting time.
Ensure all concrete ingredients, such as aggregates and admixtures, are properly measured and prepared.

Mixing Procedure:

Start by adding the required amount of water to the mixing container or concrete mixer.
Gradually introduce the dry components of the concrete mix, including cement and aggregates, and begin mixing.
Once the dry components are well-blended, slowly add LSR™ to the mixture while continuing to mix.
Ensure thorough dispersion of LSR™ throughout the entire concrete mix. Continue mixing until a uniform consistency is achieved.

Monitoring and Adjusting:

Regularly monitor the concrete’s workability, setting time, and strength development during and after mixing.
If necessary, adjust the dosage of LSR™ based on the observed setting time and desired results.
Consider conducting trial mixes or test pours to optimize the dosage of LSR™ for specific project conditions.

Placing and Finishing:

After the concrete mix is prepared, promptly transport and place it in the designated areas.
Follow standard concrete placement and finishing techniques, ensuring proper consolidation and compaction.
Pay attention to the extended setting time provided by LSR™ and adjust construction timelines accordingly.
