Fosroc Conplast SP500 KL: Uses, Advantages, Properties, Dosage, Mix Design, Packaging, and Storage

Conplast SP500 KL is a high-performance water-reducing and superplasticizing admixture that is specially formulated to offer higher water reductions without the loss of workability or to produce high-quality concrete of reduced permeability. Manufactured by Fosroc Chemicals India Private Limited, the product is marketed and supplied in India by their authorized distributor, Space Arc Engineering, for all of the Fosroc range of products. In this article, we will discuss the uses and advantages of Conplast SP500 KL in detail.

Uses: Conplast SP500 KL is widely used in the construction industry for the following purposes:

• To produce pumpable concrete
• To Produce high-strength, superior quality concrete with reduced water for low permeability and early high strength.
• To Produce concrete with excellent workability that requires minimal or no vibration during placement.

Advantages: Conplast SP500 KL offers several advantages over traditional admixtures, including:

• Improved workability: The admixture facilitates easier and quicker placing and compaction of concrete.
• Increased strength: The product provides high early strength for precast concrete if water reduction is taken advantage of.
• Improved quality: Conplast SP500 KL results in denser, close-textured concrete with reduced porosity and hence more durable.
• Higher cohesion: The admixture minimizes the risk of segregation and bleeding, thus aiding pumping of concrete.
• Chloride-free: The product is safe in prestressed concrete and with sulfate-resisting cements and marine aggregates.

Properties: Conplast SP500 KL is based on Sulphonated Napthalene Polymers and is supplied as a brown liquid instantly dispersible in water. The product meets the standards of IS:9103:1999(2007) and conforms to ASTM-C-494 Type 'G'.

Compatibility: Conplast SP500 KL can be used with all types of cements except high alumina cement. The admixture can be added separately to the mix and is compatible with other types of Fosroc admixtures. Site trials should be carried out to optimize dosages.

Dosage: Trials need to be carried out at the site to determine the exact dosage of the admixture for the particular mix design and materials. However, for normal grades of concrete, a dosage from 0.5% - 1.2% by weight of cementitious material is recommended. The dosage may be increased to 1.5% to achieve specific slump requirements. To achieve the desired water reduction and slump retention in microsilica concrete, it is essential to conduct trials to determine the appropriate dosage. Depending on the mix design and performance requirements, the dosage may need to increase up to 2.0% or even 2.5% by weight of cementitious material.

Mix design: Fosroc offers a Concrete Mix Design advisory service that can be contacted for assistance.

Packaging: Conplast SP500 KL is available in 250 Kg drums or in bulk.

Storage: Conplast SP500 KL should be stored in dry conditions and protected from extremes of temperature. When stored correctly, the product has a shelf life of 12 months.

Conplast SP500 KL is a high-performance water-reducing and superplasticizing admixture that has a variety of uses and advantages. This product is manufactured by Fosroc Chemicals India Private Limited and is marketed and supplied in India by their authorized distributor Space Arc Engineering for all of the Fosroc range of products.

This admixture is based on sulphonated naphthalene polymers and is supplied as a brown liquid that is instantly dispersible in water. It has been specially formulated to give higher water reductions without loss of workability or to produce high-quality concrete of reduced permeability.

Conplast SP500 KL is primarily used to create pumpable concrete with high-strength and grade, by significantly reducing water and resulting in low permeability and high early strength. Additionally, it can also be used to create high-workability concrete that requires minimal vibration during placement.

One of the most significant advantages of Conplast SP500 KL is that it improves workability by making placing and compaction easier and quicker. Additionally, it increases strength, providing high early strength for precast concrete if water reduction is taken advantage of. The admixture also improves quality by producing denser, close-textured concrete with reduced porosity and hence more durable. It also increases cohesion, minimizing the risk of segregation and bleeding and aiding the pumping of concrete. Furthermore, it is chloride-free, making it safe to use in prestressed concrete and with sulfate-resisting cements and marine aggregates.

Conplast SP500 KL conforms to ASTM-C-494 Type 'G' and complies with IS:9103:1999 (2007). It can be used with all types of cements except high alumina cement and is compatible with other types of Fosroc admixtures when added separately to the mix. Site trials should be carried out to optimize dosages.

The uniformity parameters such as specific gravity, pH, chloride content, etc., may vary based on the customer's specific requirements and mix design. Please refer to the MTC issued for specific product configuration for measuring product parameters that will be constantly and consistently administered.

You can use dosages outside the typical ranges mentioned above to fulfill specific needs. For assistance with mix design, Fosroc has an advisory service on Concrete Mix Design that can be contacted.

In conclusion, Conplast SP500 KL is an excellent choice for those seeking a high-performance water-reducing and superplasticizing admixture that improves workability, increases strength, improves quality, and enhances cohesion. As a product of Fosroc Chemicals India Private Limited and marketed and supplied in India by their authorized distributor Space Arc Engineering, customers can be assured of its quality and effectiveness.
