Problems solved by technology

[0004] Although the above-mentioned device realizes the temperature measurement of the cement slurry, the device directly exposes the cement slurry to the outside world for stirring and temperature measurement. Due to the great influence of external environmental factors, the temperature measurement is inaccurate, which brings serious problems to the subsequent construction. unnecessary trouble

Abstract

The invention provides a device for testing hydration heat ofcement at a constant temperature. The device comprises a heat preservation box; two sides of the inner wall of the heat preservation box are connected with a sealing plate through fixing clamping grooves, test barrels are arranged in round holes in the two sides of the upper surface of the sealing plate, a stirring device is arranged on the lower surface of the inner wall of each test barrel, and a damping device is arranged at the lower end of the outer wall of each test barrel. First rectangular sliding grooves are symmetrically formed in the upper ends of the two sides of the outer wall of the heat preservation box, each first rectangular sliding groove is connected with a second rectangular sliding groove through a connecting frame, a cover plate is arranged on the side, away from the connecting frame, of each second rectangular sliding groove, and driving devices are arranged in round holes in the two sides of the upper surface of each cover plate. Through the plug-in type stirring device, cement paste can be thoroughly stirred in a sealed environment, so that the interference of external factors is avoided, and accurate temperature measurement is carried out. The method has important significance in improving the subsequent construction quality, and has a great practical value.

Description

technical field [0001] The invention mainly relates to the technical field of heat of hydration testing equipment, in particular to a device for testing the heat of hydration of cement at a constant temperature. Background technique [0002] Heat of hydration refers to the heat released when a substance combines with water. This thermal effect is often not simply caused by hydration, so it sometimes has other names. Among them, cement with a high heat of hydration should not be used in large-volume concrete projects, otherwise the internal temperature of the concrete will greatly exceed the external temperature, which will cause greater temperature stress, and then cause cracks on the concrete surface, seriously affecting the strength of the concrete and other performance. The heat of hydration is more beneficial to concrete engineering in winter construction, and can improve its early strength. Usually in construction, it is necessary to measure the temperature of cement ...
