Fosroc Conplast Sp500 Concrete Admixture

Product Details

🔹 What It Is Fosroc Conplast SP500 is a high-performance water-reducing and superplasticising concrete admixture supplied as a brown liquid that disperses instantly in water. It is formulated using sulphonated naphthalene polymers to significantly improve concrete quality and performance. It complies with IS 9103:1999, BS 5075 Part 3 and conforms to ASTM C494 Type G standards.  🔸 Key Functions Water reduction: Reduces the amount of water required in a concrete mix (up to around 25%) while maintaining workability.  Superplasticiser effect: Enhances flowability and concrete fluidity — good for pumpable and self-placing concrete.  Improved workability: Makes concrete easier to place and compact with little or no vibration.  Higher strength: Lower water content leads to higher early and ultimate compressive strength.  Better durability: Produces a denser concrete with reduced porosity and permeability, improving long-term durability.  Higher cohesion: Reduces segregation and bleeding, helping with concrete stability and surface finish.  Chloride-free: Safe for prestressed concrete and marine environments.  📍 Typical Uses Conplast SP500 is typically used where high workability and high-strength concrete is needed, such as: Pumpable concrete mixes for large pours High-grade and high-strength concrete for precast elements Concrete requiring reduced vibration placing Infrastructure and industrial projects with demanding performance requirements    📊 Properties Form: Brown liquid, instantly dispersible in water  Based on: Sulphonated naphthalene polymers  Water reduction: Up to ~25% without losing workability  Compatibility: Works with most cements (except high-alumina cement) and other admixtures when added separately  Chloride content: Nil as per standard requirements  📋 How to Use  Add Conplast SP500 to the concrete with the gauging water during mixing. For best results, add it after pre-wetting the mix with about 80 % of the total water required. ✅ Benefits ✔ Better fluidity and flow without extra water ✔ Increased early strength and durability ✔ Easier placing and finishing ✔ Reduces segregation and bleeding ✔ Chloride-free for safety in reinforced structures In short: Fosroc Conplast SP500 is a superplasticiser admixture that enhances concrete performance by reducing water demand, increasing workability and strength, and improving overall durability — ideal for high-quality, pumpable, and high-strength concrete mixes.
