1、毕业设计（论文）题目：浅谈大体积混凝土施工的质量控制系别：建筑工程系专业：建筑工程技术班级：学生姓名：指导教师：2015年6月14日摘要目前在世界范围内，混凝土因其高强耐久、可塑性好、价格较低的优点，已经成为用途最广、用量最大的一种建筑材料。要想更较方便的运用混凝土，充分发挥混凝土的优势，保证混凝土工程的施工质量，就必须了解和掌握混凝土的强度、工作性、耐久性等各方面性能，熟知混凝土材料的各种特点。随着社会的发展，混凝土技术已进入高科技时代，品种不断增加，应用领域不断扩大，结构设计方法不断完善，相关规范

2、标准不断健全施工工艺也在不断更新。然而，混凝土工程，特别是大体积混凝土工程，其浇筑时的施工工艺，直接决定混凝土结构的强度，影响工程的整体质量，因此施工各个环节的质量管控对混凝土工程来说至关重要。目前，由于混凝土施工的一线施工人员整体素质不高，对相关的规范标准不够了解，缺乏全局观念，所以制定一套完整的质量控制体系，对大体积混凝土工程来说尤为重要。关键词：大体积混凝土、施工工艺、质量控制、规范0目录摘要·········································1一、绪论······
