Abstract

The aim of present study is to determine the mechanical properties of hollow concrete block masonry externally bonded with coir and glass textile reinforced mortar composites. The properties of textile composites were determined by testing TRM Coupons. A total number of 39 prisms were cast. The block masonry prisms were externally bonded with coir and glass textile fibre mesh with mortar. The elastic properties of block masonry, shear and flexural strength were determined for both unreinforced and strengthened specimens. The results showed that increasing the number of layers of textile fibers, enhanced the flexural capacity of TRM coupons. The provision of connectors also enhanced flexural strength. The stiffness of unreinforced masonry prisms was found to increase by strengthening with textile reinforcements even though the increase in compressive strength is marginal. There is a significant enhancement in flexural strength and shear bond strength when compared to unreinforced masonry.

纤维增强砂浆复合材料外粘结混凝土空心砌块的强度研究

本研究的目的是确定空心混凝土砌块砌体外粘接椰胶和玻璃纤维增强砂浆复合材料的力学性能。通过TRM coupon测试，确定了纺织复合材料的性能。总共铸造了39个棱镜。砌块砌体棱镜外部用砂浆粘结椰壳和玻璃纤维网。对砌块砌体的弹性性能、抗剪强度和抗弯强度进行了测定。结果表明，增加纺织纤维的层数，增强了TRM板的抗弯能力。连接器的提供也提高了弯曲强度。织物加筋后，未加筋砌体棱柱的刚度增加，但抗压强度的增加是微乎其微的。与未加筋砌体相比，在抗折强度和抗剪粘结强度方面有显著提高。

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.
