Product Overview

SikaRapid®-1 is a chloride-free, liquid concrete accelerating admixture that dramatically accelerates the hardening of concrete and reduces the time to formwork striking. It is particularly valuable in cold weather concreting where low temperatures retard normal cement hydration, and for precast concrete production where rapid mould turnaround is essential. SikaRapid®-1 can also be used to achieve design strength faster in general construction, reducing programme time. It is compatible with most Portland cement types and does not affect the long-term strength of properly designed concrete mixes. Space Arc Engineering distributes SikaRapid®-1 for precast plants, cold weather concreting, and fast-track construction projects across Delhi NCR and UP.

Applications

• Precast concrete element production for faster mould cycling
• Cold weather concreting to offset low-temperature retardation
• Rapid-strength-gain applications — floor slabs, columns, beams
• Shotcrete and tunnel support concrete
• Repair concrete requiring early loading
• Slip-form and fast-track construction

Key Advantages

• Chloride-free — no corrosion risk to steel reinforcement
• Significantly reduces time to formwork striking
• Compatible with normal Portland and blended cements
• Does not reduce long-term strength at correct dosage
• Liquid — easy to dispense via dosing equipment or by hand
• Effective even at low ambient temperatures
