Research on method of reading in temperature field of hydration heat of concrete based on ANSYS software;

Research on hydrated process and hydration heat for high added fly ash slag cement;

Effect of fly ash on the workability,strength and hydration heat of high belite cement and concrete.;

Effects of WH-Ⅱ super set retarding agent on the heat of hydration and other behavior of Portland cement;

Study of the temperature effect caused by heat of hydration in hollow-thin pier;

The effects of different kinds of mineral and chemical admixtures on the heat of hydration of the fresh cement were investigated by means of measurement of the heat of hydration and the principles of reducing or raising the heat of hydration were probed too in this paper.

Finite element ansys of hydrated heat temperature stress of the thin-walled box pier;

It is expected to develop an intelligent concrete with automatic control of hydrated heat so as to avoid or prevent thermal crack at early stage,hence to improve the durability of concrete.

The decompose,variation and formation of compounds in the hydrate processof solid alkaine component AAS cement are studied by determine and analyzing the hydrate heat and binding energy, which provided theoretical basis for further study on hydrate mechanism of this kind of cement.

0413cm 3/g and lower hydrate heat which is 253kJ/kg.

The difference is caused by various factors including large volume pouring concrete at once,hydrate heat of cement aggregating in concrete is hard to emanate,remarkable temperature rising in the concrete and quickly heat radiating of concrete surface.

The article,based on the finite element software,did calculations and analysis on the temperature stress of the construction of one arch seat,taking the elastic modulus,creep of concrete changes and casting in layers,and proposed measures to prevent cracks caused by exterior temperature changes and cement hydration heat and did some analyses on the data of temperature.

For providing design and engineering of box girder with beneficial references,the main purposes of temperature test of hydration are to grasp the regularities of(distribution) of hydration temperature follow box girder section and under considering the state of arts of concrete construction,we estimate temperature stress.

During the construction of concrete grouting pile in permafrost,the hydration provides the heat before freezing and leads to increase of the ground temperature.

During the process of peptization and hydrothermal crystallization, the aggregation behavior and the resulting morphology of nanocrystalline titania (TiO2) were studied by X-ray diffraction (XRD), scanning electron microscope (SEM), and dynamic light scattering (DLS) techniques.

Meso-pore zeolite MCM-41 was synthesized by means of microwave crystallization,room-temperature crystallization and hydrothermal crystallization.

The molecular sieve of LaSAPO is synthesized by means of hydrothermal crystallization method in the presence of surfactants CTAB and TMAOH,used as the templates.
