Abstract

The invention relates to a cement hydration heat measuring device, and relates to the technical field of testing equipment. According to the adopted technical scheme, the cement hydration heat measuring device comprises a constant temperature water bath, an insulating container and a cover body, wherein the insulating container is arranged in the constant temperature water bath and used for containing reactive materials; the cover body is provided with a charging opening, a stirring device and a temperature sensor; the cover body is detachably in sealing connection with an opening of the insulating container; the stirring device is used for stirring the reactive materials in the insulating container; the temperature sensor is used for detecting the temperature of the reactive material during the reaction, acquiring temperature data and transmitting the temperature data to a processing device. The provided cement hydration heat measuring device has the advantages that the hydration heattemperature can be detected in real time to ensure the accuracy of the detected temperature.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a cement hydration heat measuring device. Background technique [0002] Heat change is a common phenomenon in nature, it is accompanied by almost all state changes, such as: chemical reaction, biological reaction, material exchange and other processes. Cement hydration heat release is a physical and chemical reaction process between cement and water under the influence of many factors. The heat released by cement hydration will directly affect the performance indicators of concrete structures. Therefore, it is very important to accurately measure the heat of hydration of cement. In the state-owned standard, "Methods for Measuring the Heat of Hydration of Cement" stipulates that there are two methods for measuring the heat of hydration of cement, the direct method and the heat of solution method. [0003] Among them, the solution heat method has been widely used as a...
