Accelerated Curing Tank

Accelerated Curing Tank — Early Strength Prediction

The Accelerated Curing Tank is used for warm-water accelerated curing of concrete cube specimens to predict 28-day compressive strength from early-age test results as per IS 9103 and BS 1881 Part 111. Cubes are immersed at 55°C (warm-water method) for a defined period and then tested. The accelerated strength is correlated to the estimated 28-day value using established regression equations.

JS Civil Lab Solutions supplies stainless steel accelerated curing tanks with thermostat control for concrete QC labs where rapid batch acceptance is required.

Specifications

• Heating: Immersion heaters (stainless steel)
• Temperature range: Ambient to 80°C
• Temperature control: Digital thermostat, ±1°C accuracy
• Tank size: Bench-top (holds 4–8 cubes) or floor-standing (12+ cubes)
• Interior: SS 304 for corrosion resistance
• Lid: Insulated to minimise heat loss and maintain temperature
• Compliance: IS 9103, BS 1881 Part 111

Accelerated Curing Procedure (IS 9103)

Cast specimens are left in moulds for initial set (~1 hour), then demoulded and immersed in the tank at 55°C for 5.5 hours. After curing, cool in water for 1 hour and test. Apply the IS 9103 correlation factor to estimate 28-day strength. This allows batch acceptance decisions within 8 hours rather than 28 days.
