Abstract

The construction sector is responsible for relevant environmental impacts and one of its most crucial points is the use of concrete. Geopolymers represent the most promising green and ecological alternative for common Portland cement and cementitious materials, due to its proven durability, mechanical and thermal properties. This work presents an experimental and comparative study of adhesion at the fiber-matrix interface between glass fibers and carbon fibers added to the geopolymer matrix. This analysis was performed by pull-out test, whereby it was found that the greatest efficiency was obtained by reinforcing with the glass fibers, incorporated at 2 mm in the geopolymer matrix. As a result, the adhesion between the fibers and the geopolymer structure can be assessed, as well as the optimum length of application.

工业地质聚合物上的纤维基质粘附

建筑部门对相关的环境影响负责，其中最关键的一点是混凝土的使用。地聚合物具有良好的耐久性、机械性能和热性能，是普通硅酸盐水泥和胶凝材料中最有前途的绿色和生态替代品。本研究对添加到地聚合物基体中的玻璃纤维和碳纤维在纤维-基质界面上的粘附进行了实验和比较研究。该分析是通过拉出测试进行的，结果发现，在地聚合物基质中掺入2mm的玻璃纤维进行增强，可以获得最大的效率。因此，可以评估纤维和地聚合物结构之间的粘附性，以及最佳的应用长度。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
