Utilizing Industry Solid Wastes as Resource of Building Material in Chongqing

To embed or heap industry solid wastes somewhere will occupy the earth and pollute the environment seriously. So utilizing the industry solid wastes as regeneration resource is important for sustainable development of city. Based on application and research for years in utilizing industry wastes and widely investigation, the produce status of industry solid wastes in Chongqing such as fly ash, desulfuration gypsum, blastfurnace slag and chromium slag are introduced. At the same time,this paper introduces application and research on these wastes in field of building material in Chongqing. Analyze problems and countermeasures during utilizing industry solid wastes as regeneration resource in Chongqing. As a further the prospect of utilizing industry solid wastes as regeneration resource of building material is discussed.     

A Research of Life Cycle Integrated Management Pattern of Construction Project

Development Management (DM) in decision phase, Project Management on behalf of the owner (OPM) in implementation phase and Facility Management (FM) in operation phase are three isolated management tools during traditional life cycle management of construction project. As a result, a lot of potential disadvantages are aroused. In recent years, many research organizations try to reform the traditional method using different integration means. This paper tries to explore into integration of DM, OPM and FM to overcome the malpractice of traditional life cycle management of construction project. The research focuses on three aspects: 1.putting forward the concept of Life Cycle Integrated Management (LCIM), based on management integration theory; 2. Raising a new idea to owner's (operator's) management organization design, which emphasizes on the balance of life cycle objectives; 3. Analyzing an information module, level and method of system integration of Life Cycle Integrated Management Information System.

Principle and Key Technology of Full Automatic Vicat Apparatus

In this paper the working principle and performance character of both the manual and automatic Vicat apparatuses in existence are compared and analyzed,and their existing weakness and the urgent problem to be solved are pointed out.On this basis,adopting the technology of mechatronics and modern sensors,a new sort of full automatic Vicat apparatus that can fully satisfy the national standard in testing the setting time of the cement has been developed.This apparatus can be operated expediently with high precision,the test results are to be analyzed and computed automatically.This paper presents the working principle,performance character,key technology and prospect of application for the full automatic Vicat apparatus.     

Study on the Sedimentation Rule of the Particles in Debris Flow

In this paper, according to the study on a great number of experiments and data analyses, the sedimentation rule of solid particles in debris flow is set up. Three main factors that influence the particle sedimentation in debris flow were studied; the basic reasons to influence the particle sedimentation were analyzed. The particle sedimentation in debris flow could be divided into three stages,i, e. the starting stage, the quick sedimentation stage and the accumulation stage,and detailed analysis on the sedimentation process each stage was made. The liquid viscosity, particle quality and additional water pressure have an important role on the sedimentation rule of the particle in debris flow.     

Nanometer Scale Surface Roughness Measurement Based on AFM

The datum line and mainly three profile height parameters of surface roughness are briefly introduced and the operation principle and system structure of AFM. IPC - 208B with high-resolution, which was successfully developed by Chongqing University, are described in detail, and the emphasis is laid on its application on the nanometer scale surface roughness. Taking stainless steel for example, its micro-structure was observed, and the surface data were analyzed and transacted by special evaluator and the values of three profile height parameters were obtained. Finally the experimental results are briefly analyzed.     

Grid Workflow Management System Research and the Realization Based on the OGSA

Grid applications have evolved from science research to business and manufacture field, in these fields, tasks always process in workflow mode. In order to found a workflow management system in grid , the authors adopt a hybrid grid workflow engine after analyzing the characteristics of grid environment and give a referenced model of workflow management system in grid that is based on the engine. Through the examination, the authors prove the original intention is feasible.
