Step-milling Step-milling techniques was used to make High-Strength Structural Materials (HSSM) which were made of iron tailings and fly ash as the major raw materials. The impacts of the milling techniques on both the particle sizes of the mixed raw materials and the strength of HSSM were investigated. The optimized flexural strength was as high as 19 MPa for the hardened samples 28 days, and the...
Steel slag tailings were activated by heat treatment, and then mixed with blast furnace-slag, gypsum and addition to make cementitious materials. And the effect on compressive strength of water-binder ratio and temperature of heat treatment was studied. When 45 percent of the materials were heat treated steel slag tailings, its strength property was up to the requirements of the national standard...
With the development of city, the planning of underground power pipelines becomes more and more important. The layout is difficult because pipelines situate underground. They are invisible and related with many factors such as roads, buildings, transformer substations, other pipelines and so on. In order to improve planning efficiencies, a new technique based on virtual reality is presented. Firstly,...
The layout of underground transmission lines involves problems like various considerations, complex restrictions, and intensive integrated system information. This article discusses how the 3D virtual layout can be used in underground transmission lines and other applications, based on the technologies and theories of the underground transmission lines. 3D virtual transmission line system will be...
