Abstract

Concrete production is characterized by a significant demand for energy and raw materials. The construction, maintenance, and demolition of engineering works cause excessive polluting waste that requires costly disposal. For this reason, alternative reusable materials that improve the mechanical properties of concrete, such as fly ash, are currently being investigated as an effective solution to reduce problems related to environmental impact. This paper analyzed 80 articles indexed in different databases such as ScienceDirect, IOPscience, Scielo, Ebsco, Scopus, SpringerLink, ProQuest, Dialnet, and Semanticscholar, which were not older than seven years since publication, to conduct an updated systematic review of the use, effect, and influence of fly ash on concrete. The methodologies and designs used to obtain the optimum percentages of 5, 10, and 15% were reviewed, analyzing mainly the results obtained when fly ash is used in concrete. Finally, according to the review carried out, it was concluded that fly ashes improve the mechanical and physical characteristics of concrete, and that the optimum dosage is 10% in substitution of ordinary Portland cement applied in simple concrete.

粉煤灰在混凝土中的应用及效果:文献综述

混凝土生产的特点是对能源和原材料的需求很大。工程的建造、维护和拆除会产生过多的污染废物，需要昂贵的处理费用。因此，改善混凝土机械性能的可重复使用的替代材料，如粉煤灰，目前正在研究中，作为减少与环境影响有关的问题的有效解决方案。本文分析了在ScienceDirect、IOPscience、Scielo、Ebsco、Scopus、SpringerLink、ProQuest、Dialnet和Semanticscholar等不同数据库中收录的80篇文章，这些文章自发表以来不超过7年，对粉煤灰对混凝土的使用、效果和影响进行了更新的系统综述。回顾了获得5%、10%和15%的最佳比例的方法和设计，主要分析了在混凝土中使用粉煤灰时获得的结果。最后，根据所进行的综述，得出粉煤灰能改善混凝土的力学和物理特性，在简单混凝土中替代普通硅酸盐水泥的最佳掺量为10%。

期刊介绍： Revista Facultad de Ingenieria started in 1984 and is a publication of the School of Engineering at the University of Antioquia. The main objective of the journal is to promote and stimulate the publishing of national and international scientific research results. The journal publishes original articles, resulting from scientific research, experimental and or simulation studies in engineering sciences, technology, and similar disciplines (Electronics, Telecommunications, Bioengineering, Biotechnology, Electrical, Computer Science, Mechanical, Chemical, Environmental, Materials, Sanitary, Civil and Industrial Engineering). In exceptional cases, the journal will publish insightful articles related to current important subjects, or revision articles representing a significant contribution to the contextualization of the state of the art in a known relevant topic. Case reports will only be published when those cases are related to studies in which the validity of a methodology is being proven for the first time, or when a significant contribution to the knowledge of an unexplored system can be proven. All published articles have undergone a peer review process, carried out by experts recognized for their knowledge and contributions to the relevant field. To adapt the Journal to international standards and to promote the visibility of the published articles; and therefore, to have a greater impact in the global academic community, after November 1st 2013, the journal will accept only manuscripts written in English for reviewing and publication. Revista Facultad de Ingeniería –redin is entirely financed by University of Antioquia Since 2015, every article accepted for publication in the journal is assigned a DOI number.
