Fosroc Conplast Nc Concrete

Fosroc Conplast NC is a chloride‑free concrete admixture designed primarily as an accelerator of setting and early strength gain for both concrete and mortar mixes. It is supplied as a ready‑to‑use liquid that disperses instantly in mixing water and is suitable for a wide range of applications particularly where faster early strength development or cold‑weather concreting is needed 🧪 What It Is Type: Chloride‑free accelerating and water‑reducing concrete admixture Form: Light straw‑coloured liquid Standard Compliance: Meets ASTM C494 Type C and BS 5075 requirements Chloride Content: Nil — safe for reinforced and prestressed concrete ⭐ Key Features & Benefits Accelerates setting time and early strength development of cement concrete and mortar Particularly effective at low temperatures — helps offset delay in setting caused by cold weather Provides plasticising action — can improve workability and/or strength Improves frost resistance in early age concrete Chloride‑free, making it safe for use with reinforcement Also suitable for bricklaying mortar mixes 🧱 Typical Uses Concrete placed in cold weather to speed up setting and early strength Precast concrete elements for faster turnaround of forms Concrete repairs requiring quicker strength gain Mortar for brickwork to improve performance 📊 Performance & Dosage Typical dosage: ~2.0 to 3.0 litres per 100 kg of cement (optimum dose determined by trial mixes) Accelerated setting and strength effects are most noticeable in the first 24 hours after mixing Also offers a degree of water reduction or improved workability 🧠 How It Works Conplast NC accelerates the early stages of cement hydration, causing the concrete to stiffen earlier and begin strength gain sooner. This is particularly useful when concrete work must progress quickly or in conditions where normal setting would be delayed.
