Abstract

The invention provides a device and a method for testing the working performance of a dry and hard concrete mixture, and belongs to the technical field of engineering material testing. The device comprises a power box, a fixed stand column, a loading cross beam, a limiting cross beam, a counterweight drop hammer, a drop hammer connecting piece, a cylindrical steel mold, an annular ejector, a buffer rubber ring and a filling measuring rod. According to the method, the testing device is used for confirming and testing the opening void ratio of a hard concrete sample after impact compaction, the height difference of cylinders before and after impact compaction and the energy used for impact compaction of the hard concrete sample, and the working performance of the hard concrete is judged according to the three tested numerical values. The technical problems that in the prior art, due to subjectivity and limitation of concrete mix proportion adjustment and workability change of a concrete mixture caused by different production places and batches of production materials, the production applicability of the mixture is difficult to rapidly and quantitatively evaluate are solved.
