毕业设计（论文） 题目名称： 论影响混凝土强度的因素 摘 要 混凝土是以胶凝材料按适当比例配合，经搅拌、成型和硬化而成的。其强度受诸多因素的影响. 随着城市化进程的不断加快，混凝土的应用越来越广泛，在房屋，铁路、桥梁的修筑中都离不开混凝土的使用，所以混凝土对社会主义现代化建设有着举足轻重的作用。再加上混凝土具有材料来源广泛，便于施工、经久耐用等特点，预计21世纪混凝土仍是主要的建筑材料。混凝土强度是混凝土最重要的力学性能。通常用强度来控制混凝土的质量评价各种因素影响程度的指标本文Abstract Concrete is cementing material according to the proper proportion coordination, classics agitate, forming and hardening and become. Its strength is influenced by a number of factors. With the accelerating urbanization, concrete is widely used in building, railway, bridge construction in all cannot leave the concrete use, so the concrete construction of socialist modernization has a pivotal role. Combined with concrete has wide range of materials, easy construction, durable wait for a characteristic, the 21st century concrete is still a major building materials. Concrete strength is one of the most important mechanical properties of concrete. Usually use strength to control the quality of concrete and evaluation of various factors influence degree of index. This paper from the raw material and ginseng add up to agent, cement, water cement ratio, degree of finish is aggregate, age, curing the humidity and temperature, concrete construction technology, construction technology of concrete from the aspects of the paper briefly and analyzed the concrete strength of several main factors. 目 录 引言.............................................................. 1 一 原材料外加剂参合剂对混凝土强度的影响............................2 二 水泥对混凝土强度的影响..........................................3 三 水灰比对混凝土强度的影响........................................4 四 粗细集料对混凝土强度的影响......................................5 五 龄期对混凝土强度的影响..........................................6 六 养护温度和湿度对混凝土强度的影响................................7 七 混凝土施工工艺对强度的影响......................................8 八 混凝土施工技术对强度的影响......................................9 参考文献...........................................................10 致 谢.............................
