Accelerated Concrete Curing Tank

Accelerated Concrete Curing Tank is used to accelerate the curing process of concrete specimens. Curing is the process of maintaining adequate moisture and temperature conditions to allow concrete to achieve its desired strength and durability. Accelerated curing tanks create an environment that promotes faster curing by controlling factors like temperature and humidity. This helps in reducing the time required for concrete specimens to achieve sufficient strength for testing or use in construction projects. These tanks are particularly useful in situations where there is a need to speed up the construction process or when testing schedules demand quick results. Applicable for accelerating curing for concrete at construction sites and scientific research institutes for prefabricating. It predicts the strengths of rupture and resistance to compression of concrete for 7 days and 28 days for concrete molding using accelerating curing. It is a kind of special device for the quality control of concrete.

Features of Accelerated Concrete Curing Tank

  • Temperature Control: Feature precise temperature control mechanisms with a Range of Temperature up to Ambient ~ 90°C to maintain the desired curing temperature for the concrete specimens. This control ensures that the curing process occurs at the optimal temperature for accelerated strength development.
  • Humidity Control: Control over humidity levels is crucial for effective curing. Accelerated curing tanks may include humidity control systems to create and maintain the required moisture conditions for proper concrete hydration.
  • Programmable Settings: Offer programmable settings for temperature and humidity, allowing users to customize curing conditions based on specific project requirements or testing standards.
  • Stainless Steel Shelves: Corrosion-resistant, easy to clean for supporting concrete specimens during the curing process. These shelves provide a stable and hygienic surface for placing the specimens, ensuring they remain securely positioned throughout the curing period. 

Standard: ASTM C684, BS1881:112

  • ASTM C684

Outlines procedures for making and testing cylindrical concrete specimens under controlled conditions, including accelerated curing methods. The standard provides guidelines for preparing and curing concrete specimens for compression testing, with specific requirements for curing temperatures and durations to accelerate the curing process.

  • BS 1881:112

Specifies procedures for determining the compressive strength of concrete specimens, particularly cylindrical specimens, using compression testing methods. BS 1881:112 details the preparation, curing, and testing procedures for concrete specimens to assess their compressive strength, which is a crucial parameter for evaluating the quality and performance of concrete in construction projects.

Test Procedure of Accelerated Concrete Curing Tank

  • Preparation of Concrete Specimens: Prepare cylindrical concrete specimens according to the required dimensions and mix design specifications. Ensure that the specimens are properly compacted and free from any defects or air voids.
  • Setting Up the Accelerated Curing Tank: Place the accelerated concrete curing tank in a suitable location with access to power and water sources. Ensure that the tank is level and stable.
  • Temperature and Humidity Calibration: Calibrate the temperature and humidity control systems of the tank to the desired curing conditions specified in the testing standard or project requirements. This may involve setting the temperature and humidity levels according to the accelerated curing schedule.
  • Placement of Concrete Specimens: Carefully place the prepared concrete specimens on the shelves or racks inside the curing tank, ensuring that they are properly spaced and supported to prevent any movement during curing.
  • Initiating Accelerated Curing: Activate the curing cycle of the tank to begin the accelerated curing process. Monitor the temperature and humidity levels continuously throughout the curing period to ensure they remain within the specified range.
  • Curing Duration: Allow the concrete specimens to cure inside the tank for the designated period, as per the testing standard or project requirements. This duration may vary depending on the accelerated curing method used and the desired strength development of the concrete.
  • Quality Control and Monitoring: Regularly inspect the concrete specimens during the curing process for any signs of cracking, deformation, or other defects. Adjust the curing conditions if necessary to maintain optimal curing parameters.
  • End of Curing Cycle: Once the curing period is complete, deactivate the curing cycle of the tank and allow the specimens to reach ambient temperature gradually.
  • Removal of Concrete Specimens: Carefully remove the cured concrete specimens from the tank, taking precautions to prevent any damage or disturbance to the specimens.
  • Testing of Concrete Specimens: Conduct compression tests on the cured concrete specimens according to the applicable testing standard (e.g., ASTM C684 or BS 1881:112) to determine their compressive strength and other mechanical properties.
  • Recording and Reporting: Record all relevant data and observations obtained during the curing and testing process. Prepare a detailed report documenting the test results, including the compressive strength values of the concrete specimens.
