Concrete shrinkage test mold

The utility model provides a concrete shrinkage test mould which comprises a mould shell and a pair of end covers, the front end and the rear end of the mould shell are respectively provided with a pair of positioning steps, the space between the positioning steps serves as a pouring cabin, the end covers are sleeved in the pouring cabin, and the end faces of the outer ends of the end covers are provided with sinking grooves. By the adoption of the technical scheme, the maximum length size of the concrete test block is limited through the positioning steps, in the whole process of a concrete shrinkage test, the working procedure that a transverse pin is used for limiting the relative position between the end cover and the mold shell is omitted, the operation working procedure is simplified, the edge of the sinking groove can serve as an acting point in the demolding process, and the service life of the concrete test block is prolonged. When the demoulding mechanism applies force to the end cover, the slipping
