linear expansivity
- 文摘:研究了机械力化学改性对高钙粉煤灰混合水泥基本材料的影响，通过对混合水泥硬化浆体的雷氏夹膨胀值、自由线膨胀率和强度等物理性能的试验测定，揭示了机械力化学改性对高钙粉煤灰水泥基材料改性的重要作用，并阐明了其作用机理。
Abstract: The effects of the mechanochemical improvement on the properties of compounding cement with high calcium fly ash are studied.By testing the physical properties of the hardened cement paste such as Le Chatelier's expansion value,free expansion ratio,strength and so on,the important influences on the mechanochemical improvement on the cement with high calcium fly ash are showed.And the improvement mechanism is also explained.
