Concrete Curing Boxes

Concrete Curing Boxes are a portable solution for protecting newly made concrete test specimens in accordance with ASTM C31 and AASHTO T 23. These sturdy, lightweight, insulated boxes help maintain required temperatures during the critical initial curing phase. Temperatures for intial standard curing are specified to be in the range of 60°–80°F (16°–27°C) for design strengths less than 6,000psi (40MPa), and 68°–78°F (20°–26°C) for strengths 6,000psi (40MPa) and greater. Curing box models with heating and cooling functionality or with heating only are available.

• Perfa-Cure Concrete Curing Boxes come in models that provide heating and cooling or heating only. All models are compatible with 6x12in (152x305mm) or 4x8in (102x203mm) concrete cylinders. Insulated units feature lightweight plastic construction, hinged lids with gaskets, and a dial controlled thermostat for accurate regulation of ambient air temperature. The sealed lids effectively control evaporative loss. A mini model with heating only is available for increased portability and convenience.
• Thermocure Portable Curing Boxes depend on immersion of conrete samples in water for temperature control and are available as Deluxe or Economy models. Both models feature a lockable lid and a removable galvanized steel bottom rack. The temperature control unit of the Deluxe version recirculates heated or cooled water to regulate temperature and control moisture loss. Temperature regulation shifts automatically between warm or cold weather conditions. Operation is simple using temperature control arrow buttons. The Economy model is best for cool or cold weather applications and features a heating system with an adjustable thermostat. Some cooling can be accomplished by circulating freshwater.
• Field Curing Chest offers ease of storing and transporting, as well as protection from harsh elements. Samples are passively warmed by heat of hydration from the samples and the chest reduces the loss of moisture by evaporation. The chest is lightweight, foldable, and can be stored in minimal space for quick deployment.
