Description

Technical Field

[0001] This utility model relates to the field of water tightness density testing technology, specifically to a cement mortar vibration table. Background Technology

[0002] Cement strength is an important indicator for evaluating cement quality and is the basis for classifying cement strength grades. Cement strength refers to the ability of a hardened cement mortar specimen to withstand external force failure, expressed in MPa (megapascals). It is one of the important physical and mechanical properties of cement. According to different stress forms, cement strength is usually divided into three types: compressive strength, flexural strength, and tensile strength. The maximum stress when a hardened cement mortar specimen is subjected to compressive failure is called the compressive strength of cement; the maximum stress when a hardened cement mortar specimen is subjected to flexural failure is called the flexural strength of cement; and the maximum stress when a hardened cement mortar specimen is subjected to tensile failure is called the tensile strength of cement.

[0003] Upon inspection, it was found that the publication (announcement) number CN205665082U describes a cement mortar vibration table. The key technical points of this table are: a cement mortar vibration table including a base and a swing arm with one end rotatably connected to the base and the other end connected to the base via a cam mechanism. A vibration platform is fixedly connected to the swing arm, and a pressure frame for vertically fixing a mold sleeve is rotatably connected to the vibration platform. The vibration platform has a limiting block located on one side of the pressure frame, and the pressure frame has an abutting member away from the limiting block. The pressure frame has a transmission component for driving the abutting member closer to or away from the limiting block. This invention is simple to install and mainly uses the limiting block and the abutting member to horizontally fix the mold sleeve, preventing it from shifting from the vibration center position during vibration, thus improving the vibration effect. This facilitates testing of cement mortar, thereby improving the quality of cement used in construction and contributing to refined construction and green building construction. Since different sizes of cement require different mold sleeves, and changing mold sleeves is cumbersome, this cement mortar vibration table is proposed. Utility Model Content
