The 3R on-site curing box is designed to enable storage of concrete specimens on site, in an enclosed, protected and transportable space.
It provides a simple solution to protect specimens from immediate external conditions (sun, wind, dust) after sampling, without requiring heavy infrastructure. A water reserve can be placed at the bottom of the box to limit concrete drying.

From design to machining, from software to hardware: complete control of the value chain for custom testing machines.
