粉煤灰混凝土力学性能及耐久性研究
Study on Mechanical Properties and Durability of Fly Ash Concrete

随着人们保护环境的意识以及可持续发展观念的日益增强，绿色环保混凝土愈发得到人们的重视，逐渐成为混凝土材料发展新方向。掺合料混凝土就是绿色混凝土的代表，当前人们对掺粉煤灰的混凝土虽然进行了一些研究，但研究成果并未达成共识，亟待进行全面深入研究。本文试图通过多项试验对掺粉煤灰混凝土的多项物理性能，如：抗压、抗渗、抗碳化、抗冻的性能以及用CT扫描对试块内部的微观结构进行了全面深入研究。
With the increasing awareness of environmental protection and the concept of sustainable development, green concrete has been paid more and more attention and gradually become a new direction for the development of concrete materials. Admixture concrete is the representative of green concrete. Although people have carried out some research on fly ash admixture concrete at present, the research results have not reached a consensus, and comprehensive and in-depth research is urgently needed. This paper attempts to conduct a comprehensive and in-depth study on the physical properties of fly ash doped concrete through a number of tests, such as compressive, impermeable, carbonized and freeze-resistant properties, as well as the internal microstructure of the test block by CT scanning.
