The utility model discloses high temperature and microthermal concrete experiment machine can apply simultaneously in concrete test block, this experiment machine includes: temperature control machine, circulating line, concrete test mould. Temperature control machine includes temperature regulation apparatus, air compressor, resistance heating device, circulating water pump, and temperature regulation apparatus adjusts the temperature of circulation liquid, and circulating water pump will circulate the agent at the pipeline inner loop, and air compressor and resistance heating device freeze or heat the thermal cycle agent, the circulating line adopts flexible steel mesh pipe, outside parcel insulating foam panel, concrete experiment mold adopts components of a whole that can function independently detachable trigeminy modular form, and heating refrigeration face adopts high strength steel plate, and the circulating line has been inlayed to the outside, and the thermal -insulated plastics of high -strength polyethylene are adopted to other positions. During the experiment, directly pour the concrete in the mould, according to the experiment requirement, open temperature control machine, carry out temperature simulation to the concrete, after the experiment, close temperature control machine, unpack the mould apart, take out the concrete test block.
