| Summary: | 碩士 === 國立高雄應用科技大學 === 土木工程與防災科技研究所 === 106 === The concept of sustainable development has become more and more important in recent years. Economic development needs to be based on the protection of the Earth's natural ecological system and environment. How to save energy and reduce carbon emissions and effective use of resource materials has become a goal of various countries, among which green recycling materials are used. Environmental protection cement has become a topic of environmental protection that has been given special attention by all walks of life.
The analysis of the chemical composition of the stainless steel reducing crucible shows that it is mainly composed of calcium oxide (CaO), lanthanum oxide (SiO2) and a small amount of alumina (Al2O3), and has a small particle size and a high specific surface area and has the potential as a bismuth material. Since reducing calcium oxide in the crucible can help alkali activation, it is suitable as a bismuth material.
In this study, the use of stainless steel after the stabilization of the reduction of thorium made of environmentally friendly cement to replace the ordinary cement, made of cement mortar, to explore the impact of environmental protection cement with different amounts of substitution on the nature of the new and hard-solid engineering, to assess the volume stability of environmental protection cement, as The feasibility assessment of environmental protection cement makes this byproduct fully and effectively utilized.
The results showed that when the amount of stainless steel reduction environmental protection cement is replaced, the cement mortar increases the lubrication between pellets in the mixing process, thereby improving the workability, showing that stainless steel reduction slag environmental protection cement can increase the workability of stainless steel in different fineness When reducing the amount of yttrium replaced by 20% of cement, the strength is more than 80% of that of pure cement mortar.
