Abstract
En este trabajo se han estudiado las caracteristicas en estado fresco de un hormigon autocompactante (HAC) reforzado con fibras de acero (HACRFA). Los resultados obtenidos permiten comprobar que, a pesar del contenido en fibras del hormigon, lo cual contribuye a disminuir de forma importante las caracteristicas de autocompactabilidad, el hormigon puede definirse como autocompactante con las exigencias de la Instruccion EHE 08. Sin embargo, el HRFA ensayado posee una dosificacion de fibras relativamente baja, 0.4% en peso de hormigon, por lo que los resultados obtenidos no pueden extrapolarse a HRFA con contenidos en fibras superiores Abstract In this work the characteristics in the fresh state of a self-compacting concrete (SCC) reinforced with steel fibers (SCCSF) have been studied. The results obtained allow us to verify that, despite the fiber content of the concrete, which contributes to significantly reduce the characteristics of self-compactability, the concrete can be defined as self-compacting with the requirements of Instruction EHE 08. However, the SFC tested It has a relatively low fiber dosage, 0.4% by weight of concrete, so the results obtained cannot be extrapolated to SFC with higher fiber content.
本文研究了钢纤维增强自压混凝土(HAC)在新鲜状态下的特性。根据EHE 08的要求,混凝土可以被定义为自压实的,尽管混凝土的纤维含量大大降低了自压实特性。然而,HRFA测试纤维具有dosificacion hormigon相对较低,重量的0.4%,因此不能成果HRFA纤维内容超过Abstract In this work the分离器In the新鲜state of a self-compacting具体(SCC)加强with SCCSF钢铁fibers)得到studied。所获得的结果使我们能够验证,尽管混凝土的纤维含量大大降低了自压实特性,但根据EHE 08指令的要求,混凝土可以定义为自压实。然而,SFC测试它的纤维含量相对较低,按混凝土重量计算0.4%,所以得到的结果不能外推到纤维含量较高的SFC。
