Cement hydration heat calorimeterIt is a professional equipment used to detect the heat release during the hydration process of cement, widely used in cement plants, scientific research institutions, and construction engineering fields. The core principle is based on precise monitoring of heat changes during the cement hydration process. Common methods include direct method and dissolution heat method. The direct method is to automatically record the temperature changes of cement mortar through high-precision temperature sensors under the condition of a constant temperature around the calorimeter, calculate the total amount of accumulated and dissipated heat in the calorimeter, and thus obtain the hydration heat of cement within a certain period of time. The law of heat of dissolution is based on Geiss's law, which measures the difference in heat of dissolution between unhydrated and hydrated cement at a specific age in standard acid, in order to determine the heat of hydration released by cement during the specified age.
Cement hydration heat calorimeterThere are significant product advantages in the research of cement and concrete, mainly reflected in the following aspects:
1. High precision and high stability
The cement hydration heat meter adopts advanced temperature control technology (such as Peltier temperature control and air circulation constant temperature), with a temperature control accuracy of ± 0.002 ℃ and a detection limit as low as 1 μ W, which can accurately capture small heat changes during the cement hydration process. For example, the temperature stability of the MIC-90 model is ± 0.002 ℃, with a baseline drift of less than 5 μ W, ensuring the reliability of the data.
2. Multi channel design improves efficiency
Support multi-channel parallel testing (such as 8-channel), which can analyze multiple samples or different formulations simultaneously, significantly improving experimental efficiency. For example, both JQ-ITC8 and MIC-90 models support an 8-channel configuration, making them suitable for horizontal comparative studies.
3. Intelligent and Automated Operations
The instrument is equipped with an automated data acquisition and analysis system, such as automatic sampling, real-time software generation of hydration heat release curves, Excel data export and other functions. The preparation of a single sample only takes 2 minutes, without the need for manual supervision, reducing human errors.
4. Environmental Protection and Safety
The testing process does not require the use of strong acids (such as HF, HNO), and there are no harmful gas or liquid emissions, which meets the requirements of green experiments.
5. Widely applicable adaptability
In addition to cement hydration heat analysis, it can also be used for microbial growth monitoring, polymer solidification research, etc. For example, the MIC-90 model supports in-situ mixing and stirring, adapts to sample tanks of different materials, and meets diverse scientific research needs.
6. Flexible configuration and scalability
Some models support modular switching (such as 3-channel and 8-channel interchangeability), with optional sample pool volumes (20mL-100mL) and customizable materials and shapes to adapt to different experimental conditions.
