Since the main cementitious material in the experimental sample is cement, its coagulation and solidification is an exothermic reaction process. If the demoulding time of the sample is too late, it is likely to miss the best curing time for the demoulded sample, which will cause the quality of the sample to deteriorate. become worse
However, the demoulding time is too early. At this time, the solidification and solidification of the sample is in the initial stage, and the sample has not yet ful...

Abstract
The invention discloses a reserved chamber simulating test piece manufacturing die assembly and a method used for manufacturing a test piece. The die assembly comprises a model shell, a solid cylinder, a round through hole, clamps, a bearing plate and a cylinder containing cavity, wherein the model shell has a splitting structure and is formed by two symmetrical parts; a hexahedral sample adding cavity is arranged at the upper part of the model shell, and a press is used for compacting and shaping a sample in the cavity by the bearing plate. The die assembly has a simple structure, and is convenient to disassemble, and the sample can be subjected to mold release conveniently. The invention also discloses the method for manufacturing the test piece by adopting the reserved chamber simulating test piece manufacturing die assembly. The method comprises the steps of assembling a mold, adding the sample, pressurizing the sample, separating the mold, and disassembling the mold. According to the test piece manufactured by adopting the method for manufacturing the test piece by the die assembly, the test piece can be subjected to mold release conveniently, and the pressurized shaping effect of the test piece is good.
Description
technical field [0001] The invention relates to a mold assembly for a simulated test piece and a method for preparing the simulated test piece, in particular to a mold assembly for preparing a simulated test piece with a reserved chamber and a method for preparing the test piece. Background technique [0002] In engineering construction, it is often necessary to study the deformation and evolution of the surrounding rock after chamber excavation. Therefore, it is necessary to carry out relevant research on reserved chambers in advance to conduct simulation tests on discontinuous rupture areas, cracks, and support conditions. In the laboratory, iron powder, barite powder, gypsum powder, lime powder, quartz sand, river sand, clay, wood chips, etc. are generally used with cement, zinc oxide, paraffin, rosin, alcohol, white latex, resin, etc., according to A certain ratio is mixed into a slurry material, and then made into a test piece, and then the next step of the experimental...
