Abstract

The findings from the investigation conducted, to compare the structural performance of concrete containing treated (TOPEFB) and untreated Empty Oil Palm Fruit Bunch (OPEFB) fibres are presented in this paper. For the TOPEFB fibres, the dried fibres were treated with 0.2% NAOH solution following the procedures of appropriate authority. The structural parameters investigated were consistencies, setting times, densities, compressive and tensile strengths of concrete incorporating TOPEFB and OPEFB fibres in the mix. The addition of fibres was limited to 1.20% by weight of cement in the concrete. The interval of addition was 0.2%. The results showed that (i) the setting times of mortars containing TOPEFB fibres were higher than that of mortars with OPEFB fibres, (ii) concrete specimens containing TOPEFB fibres are more workable that concrete specimens with OPEFB fibres, (iii) densities of concrete specimens containing OPEFB fibres were in the range for normal concrete applications while the densities for specimens with TOPEFB developed densities that fell in the heavy weight concrete classification, (iv) concrete specimens containing TOPEFB fibres developed higher compressive strengths than specimens with OPEFB fibres and (v) tensile strengths of concrete specimens containing TOPEFB fibres were higher than specimens with OPEFB fibres by at least 59.04%. The overall conclusion from the findings of this study is that concrete specimens containing TOPEFB fibres have superior structural properties than specimens with OPEFB fibres

油棕空果束(TOPEFB)和未处理油棕空果束(OPEFB)纤维增强混凝土结构响应的比较研究

从调查结果进行，以比较混凝土的结构性能含有处理(TOPEFB)和未经处理的空油棕榈果束(OPEFB)纤维在本文中提出。对于TOPEFB纤维，按照适当的权威程序，用0.2% NAOH溶液处理干燥的纤维。研究的结构参数包括掺入TOPEFB和OPEFB纤维的混凝土的浓度、凝结时间、密度、抗压强度和抗拉强度。纤维的添加量被限制在混凝土中水泥重量的1.20%。添加间隔为0.2%。结果表明:(1)含TOPEFB纤维砂浆的凝结时间比含OPEFB纤维砂浆的凝结时间要长;(2)含TOPEFB纤维的混凝土试样比含OPEFB纤维的混凝土试样更可行;(3)含OPEFB纤维的混凝土试样的密度在正常混凝土应用范围内，而含TOPEFB纤维的混凝土试样的密度则落在重质混凝土分类中。(iv)含有TOPEFB纤维的混凝土试件的抗压强度高于含有OPEFB纤维的试件;(v)含有TOPEFB纤维的混凝土试件的抗拉强度至少比含有OPEFB纤维的试件高59.04%。本研究结果的总体结论是，含有OPEFB纤维的混凝土试件比含有OPEFB纤维的试件具有更好的结构性能

期刊介绍： The Electronic Journal of Structural Engineering (EJSE) is an international forum for the dissemination and discussion of leading edge research and practical applications in Structural Engineering. It comprises peer-reviewed technical papers, discussions and comments, and also news about conferences, workshops etc. in Structural Engineering. Original papers are invited from individuals involved in the field of structural engineering and construction. The areas of special interests include the following, but are not limited to: Analytical and design methods Bridges and High-rise Buildings Case studies and failure investigation Innovations in design and new technology New Construction Materials Performance of Structures Prefabrication Technology Repairs, Strengthening, and Maintenance Stability and Scaffolding Engineering Soil-structure interaction Standards and Codes of Practice Structural and solid mechanics Structural Safety and Reliability Testing Technologies Vibration, impact and structural dynamics Wind and earthquake engineering. EJSE is seeking original papers (research or state-of the art reviews) of the highest quality for consideration for publication. The papers will be published within 3 to 6 months. The papers are expected to make a significant contribution to the research and development activities of the academic and professional engineering community.
