Static cracking agent expansion pressure and temperature testing integrated device and testing method thereof

Abstract

The invention provides a static cracking agent expansion pressure and temperature testing integrated device. The static cracking agent expansion pressure and temperature testing integrated device comprises supporting legs, a base, a hydraulic jack, a left stand column, a right stand column, a top seat, a guide rod, an upper fixing plate, an upper sealing piston, a pressure cell, a supporting limiting nut, a cylinder barrel and a pressure gauge; exhaust passages communicated with the interior of the cylinder barrel are arranged in the upper sealing piston and the upper fixing plate, sealing bolts are arranged at the outer ports of the exhaust passages, a mounting hole is formed in the side part of the cylinder barrel in a radial direction, and a thermometer is arranged in the mounting hole.The invention further discloses a testing method of the static cracking agent expansion pressure and temperature testing integrated device. The device can achieve the purpose of testing the expansionpressure and temperature in the hydration process of static cracking agents with different properties, is easy to carry, high in testing efficiency and testing speed and low in testing cost, can be used repeatedly, can be applied to different environments, and is suitable for testing the expansion pressure and temperature of the static cracking agents in different fast and common slow reactions.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, and in particular relates to an integrated device for testing expansion pressure and temperature of a static breaking agent and a testing method thereof. Background technique [0002] Since its inception, the static breaker has been widely used in the fields of safe demolition of concrete structures, bedrock excavation, stone forming and cutting, boulder crushing and other fields. Among them, the size of the expansion pressure directly determines the crushing effect of the static crushing agent, which is the most important performance index to measure the static crushing agent; and the expansion process of the static crushing agent will release a lot of heat, and the accumulation of heat will further strengthen the static crushing The cracking effect of the agent, the temperature index in the expansion process is an important index to measure the heat of reaction.

AI Technical Summary

Problems solved by technology

[0003] At present, the expansion pressure of the static breaking agent is generally tested, and the test is only carried out in the laboratory, the structure is complex and inconvenient to carry, and the expansion pressure and temperature are not integrated into the test, so the test results are certain. error
