双语例句
- Chemical analysis, XRD, conduct calorimeter and compressive strength test are used in studying of the hydration of C_3S doped with CaF_2. Results show that the degree of hydration, the chemically combined water, the rate of heat evolution and compressive strength are decreased with increasing(?)
用化学分析、XRD、传导量热仪和测定抗压强度等手段研究了含氟C3S的水化。结果表明，随着（？） - Effects of gypsum and calcined gypsum on the early hydration of portland cement were investigated by means of DTA, XRD, IR, and chemically combined water and Ca ( OH) 2 content.
利用DTA，XRD，IR测定水泥水化浆体的化学结合水和Ca（OH）2的生成量，研究了煅烧石膏、二承石膏对硅酸盐水泥早期水化过程的影响。 - The water absorption and chemically combined water content continually decrease, and the compressive strength, bending strength and impact strength continually increase as SPS content increases.
随着SPS掺量的增大，水泥净浆的吸水率和化学结合水量进一步减小，抗压强度、抗折强度和冲击强度进一步提高； - The experimental results indicate that the increase of content of fly ash facilitates early hydration of cement, but decreases chemically combined water and compressive strength of hardened pastes at the same time.
试验结果表明：粉煤灰掺量的增加虽然促进了水泥的早期水化，但仍然降低了硬化浆体中化学结合水总量，同时，随粉煤灰掺量的增加，硬化浆体的早期强度下降； - The amount of chemically combined water gets in large quantity in the first day and increases steadily till 7th day.
一直到第7d，化学结合水量仍然明显增加； - Results show that the cement pastes with calcined gypsum had more Ca ( OH) 2, less chemically combined water and no ettringite in the first day of hydration in comparison with the cement pastes with gypsum.
结果表明：在水化龄期相同时，掺煅烧石膏水泥浆体中水化产物同掺二水石膏相比，Ca（OH）2生成量大；在1d前无钙钒石（AFt）生成；
