Abstract: A concrete temperature stress testing machine system and a testing method are provided, in which the concrete temperature stress testing machine system includes: a concrete temperature stress testing machine and a walk-in environment simulation laboratory system; and the concrete temperature stress testing machine includes a testing machine host and a concrete test specimen area. The testing machine host includes a rear fixed end, a front fixed end, and a pair of steel shafts connected between the rear fixed end and the front fixed end. The concrete test specimen area includes a moveable cross-head, a fixed cross-head, and a left side formwork, a bottom formwork and a right formwork connected between the moveable cross-head and the fixed cross-head.

Abstract: A concrete temperature stress testing machine system including: a concrete temperature stress testing machine and a walk-in environment simulation laboratory system; and the walk-in environment simulation laboratory system includes a walk-in environment simulation laboratory, a host control cabinet, a compressor set room, an environment room control cabinet and a computer. The concrete temperature stress testing machine achieves the temperature deformation self-compensation by using the combination of different proportions of invar and No. 45 steel, an embedded type directly measuring deformation technology of the concrete temperature stress testing is achieved by the fit between the upper and side embedded parts, the embedded rod and the extending rod.
