Universal cement mortar test mold

Abstract

The invention discloses a universal cement mortar test mold and relates to the technical field of molds. The universal cement mortar test mold comprises a bottom plate, a front baffle, a rear baffle, at least one transverse partition plate, a plurality of longitudinal partition plates and two pressure applying devices connected to the two sides of the top face of the bottom plate correspondingly, and the front baffle and the rear baffle are oppositely arranged at the two ends of the top face of the bottom plate; the two pressure applying devices are used for pushing the front baffle and the rear baffle to move towards each other, the transverse partition plate is arranged between the front baffle and the rear baffle, one end of each longitudinal partition plate abuts against the transverse partition plate, and the other end of each longitudinal partition plate abuts against the front baffle, the rear baffle or the other transverse partition plate. The front baffle or the rear baffle, the bottom plate, the transverse partition plate and the longitudinal partition plates define a plurality of mold cavities with openings in the tops. According to the universal cement mortar test mold, the multiple mold cavities can be rapidly and efficiently isolated, the integrity, stability and sealing performance of mold assembly are effectively improved, and the mortar leakage probability is reduced.

Description

technical field [0001] The application relates to the technical field of molds, in particular, to a general-purpose cement mortar test mold. Background technique [0002] In the relevant detection tests of cement-based materials, there are many types and quantities of tests related to mortar. Under normal conditions, different molds need to be made for different test contents, which brings various inconveniences: A large number of different molds occupy limited laboratory space, are expensive, and occupy scientific research costs; some relatively infrequent molds are idle for a long time, resulting in waste of resources; individual tests such as shear bond strength need to be completed. Hand-made foam blocks seriously affect the efficiency of test piece forming and the accuracy of test piece size, which in turn leads to large deviations in test results. In addition, traditional steel molds (cast iron molds) have problems of poor fixability and sealing, and slurry leakage is...

[0002] In the relevant detection tests of cement-based materials, there are many types and quantities of tests related to mortar. Under normal conditions, different molds need to be made for different test contents, which brings various inconveniences: A large number of different molds occupy limited laboratory space, are expensive, and occupy scientific research costs; some relatively infrequent molds are idle for a long time, resulting in waste of resources; individual tests such as shear bond strength need to be completed. Hand-made foam blocks seriously affect the efficiency of specimen forming and the accuracy of specimen size, which in turn leads to large deviations in test results

In addition, traditional steel molds (cast iron molds) have problems of poor fixability and sealing, and slurry leakage is prone to occur during the molding process of test pieces, especially in vibration conditions, which also seriously affects the The quality of test piece production
