The measurement and characteristic analyses of cement mineral hydration rates

Abstract：The content of the chemical combined water and hydration rate are the important parameters for studying the conversion of the chemical composition in cement mineral and the durability of the cement construction materials.Through measuring the content of the chemical combined water of cement, namely hydration rate, which was hydrated in different solution and different period to indirectly determine cement hydration velocity.Amount of factors and problems, which easily impact the measurement of the loss of weight on ignition and the content of the chemical combined water, was studied.Some improvement methods were brought up to measure the quantities of freshness loss of weight on ignition and the content of the chemical combined water about cement more accurately.Along with it, the precise hydration instance of different composition cement in same hydration period was measured.Through analyzing the experimental data, different cement hydration law was got out, which is able to offer reference to further study of cement materials.
