产品介绍

1. Product Introduction

The isothermal conduction calorimetry method can fully describe the hydration process of cement paste within a specified age, providing the development curve of cement hydration heat release rate over time. It is particularly suitable for accurately measuring the hydration heat characteristics of cement within 24 hours. The instrument is mainly used for mass concrete in hydropower projects, crack‑resistant concrete for railways and highways (using isothermal conduction calorimetry), nuclear power crack‑resistant concrete, marine engineering concrete, and high‑rise building foundation concrete. It is developed in accordance with the cement hydration heat determination method – isothermal conduction calorimetry (reference method) as specified in GB/T 12959‑2024 Test Methods for Heat of Hydration of Cement.
