Civil Engineering Materials Laboratory Improvement

9452197杜威土木工程及环境工程系现正重整土木工程材料课程的顺序，以确保毕业生具备环境知识和技术能力。经修订的三个课程序列的统一主题包括认识到材料的获取和使用对环境的影响，以及制定和使用材料评价方案作为决策工具。课程顺序包括土木工程材料特性入门课程、土木工程复合材料课程和土壤特性课程。实验室经验被认为对理解和欣赏材料行为很重要，这些修订的材料课程将提供广泛的动手机会，以了解实验程序和确定材料特性。实验室体验将从手动设备操作和数据收集开始，并进展到计算机控制的实验以及自动数据收集和显示。所考虑和表征的材料包括传统建筑材料以及工业和消费后残留物。对非常规或新型材料的认识将使研究生工程师能够有效地利用这些材料，作为污染预防工作的重要组成部分。根据该项目采购的一个手动通用测试框架和数据采集系统将安装在便携式手推车上，以便在以后的设计课程中进行课堂演示。

9452197 Dewey The Civil and Environmental Engineering Department, as part of the effort to insure that graduates are environmentally literate as well as technically competent, is restructuring the Civil Engineering Materials course sequence. Unifying themes of the revised three course sequence include an awareness of the environmental impact of material acquisition and use along with the development and use of material evaluation protocols as decision making tools. The course sequence includes an introductory class in civil engineering material properties, a class in civil engineering composites, and a class in properties of soils. Laboratory experiences are considered important to the understanding and appreciation of material behavior, and these revised materials classes will provide extensive hands-on opportunities to understand experimental procedures and determine material properties. The laboratory experience will start with manual equipment operation and data collection and progress to computer controlled experiments coupled with automated data collection and display. Materials considered and characterized include traditional construction materials as well as industrial and post-consumer residuals. An awareness of non-conventional or novel materials will permit graduate engineers to effectively utilize these materials as an important part of pollution prevention efforts. One of the manual universal test frames and a data acquisition system procured under this project will be mounted on a portable cart to permit classroom demonstrations in later design classes.
