Fully automatic cement hydration heat measurement system (new model)
Fully automatic cement hydration heat measurement system (new model)
Product details
This system was developed by our company in 2006 in accordance with the national standard GB-T 2022-1980（Now updated to GB/T 12959－2008）The development of a direct method for testing the hydration heat of cement, which is used to automatically record the temperature changes of cement binder in multiple sets of calorimeter, calculate the total amount of accumulated and dissipated heat in the calorimeter, and thus obtain the hydration heat of cement within 7 days (28 days). The system is fully automated, with dense sampling points and high accuracy, fully replacing old-fashioned manual reading instruments. It can be used in cement plants, scientific research departments, colleges and universities, and construction engineering departments. It is an essential equipment for detecting the hydration heat of cement such as "dam cement", "Portland cement", "slag Portland cement", "fly ash Portland cement", and additives.
The use of this system eliminates the problem of traditional instruments requiring manual duty for reading and large errors in reading recording. Once the sample is installed, manual intervention is no longer needed. The system will automatically control the collection/recording/stopping/analysis/calculation of hydration heat data according to program settings and print hydration heat detection reports. The system uses high-precision temperature sensors to collect the temperature changes of cement in the calorimeter. Multiple sets of calorimeters are installed in a constant temperature circulating water tank with a numerical control device to ensure a constant external temperature. The changes in heat values are collected in real time by a multi-channel data acquisition device and transmitted to the computer. The software automatically analyzes the data to obtain the cement heat release curve and total heat value within 7-28 days.
The system has now beenChengdu Survey and Design Institute, Central South Survey and Design Institute, Yangtze River Academy of Sciences, Beijing Building Materials Science Research Institute, Gezhouba Testing and Inspection Co., Ltd., Hydroelectric Power7Research Institute of the Bureau, Hohai University, Guangzhou University, Lafarge Cement Co., Ltd. (French funded), Tenglong Cement Co., LtdMany domestic scientific research, experimental, and production units have adopted it.

2014 New Product Features:
--The new water bath adopts a large screen color LCD controller and is installed with a tilted panel, which has a beautiful appearance and effectively prevents water droplets from the tabletop from entering the operation panel
--The heat meter bracket frame of the new water bath is made in an integral basket style, which can be lifted out of the sink as a whole when not in use, making it convenient for cleaning the bottom of the sink and preventing water rust
--The new water bath can be used as a large volume constant temperature water bath by extracting the bracket frame of the entire hydration heat sample without conducting a hydration heat test
--The new water bath has lower noise and more stable operation
--The new water bath offers multiple versions including 6-hole, 8-hole, 10 hole, 12 hole, and 16 hole according to user requirements
--The new software adopts multi page and multi-channel operation under the same window, and the error or unexpected termination of a single channel test will not affect the normal operation of other channel tests
--The new software can be provided in multiple versions, including a 7-day standard version and a 28 day extended version
