Effect of water-binder ratio and composition on the hydration products and hydration degree of complex shrinkage-compensating binders;

The effects of mineral materials, grinded blast furnace slag (S), high-calcium fly ash (HF), desulfurized gypsum (DG), calcined desulfurized gypsum (CG) and sodium sulfate (NS) on the hydration degree of cement pastes are researched according to testing results of the chemical shrinkage, the hydration heat and the compressive strength.

In this paper, the modeling and simulation process of CEMHYD3D is analyzed, the hydration process of CCRL Cement 133 at different water-to-cement ratios is simulated with CEMHYD3D, and several properties, such as the hydration heat, the hydration degree, the variation of the reactant and the product are predicted.

In pozzolanic effect, the degree of hydration was calculated according to the hydration model and the measured parti.

A computer simulation-based method is presented for predicting the degree of hydration.

The samples with different content of dehydrated phase of hydrated cement paste were prepared to study the influence of heat treatment on their rehydration abilities which were evaluated with the water requirements for normal consistency,the initial setting time,rehydration degree and compressive strength.

5) subjected to high temperatures were evaluated by the water requirements of standard consistency,the setting times,the compressive strength,rehydration degree and mineral analysis by XRD.

According to operational principle of pyrolysis gas chromatography and its judgment on water flooded formation, the new technique of judging water flooded formation applied pyrolysis gas chromatography data, combined logging data, well testing data and test production data, and carried on evaluation on water flooded degree by using the example of Fuyu oil field closed core well.
