Basalt Fibre Reinforced Polymer (BFRP) reinforcement for reinforced concrete is two times stronger and four times lighter than steel reinforcement. This means fewer resources would be required for reinforced concrete structures than conventional steel reinforced concrete, facilitating safer construction of reinforced concrete structures and more efficient logistics. Unlike steel, it is naturally resistant to chemicals and does not corrode. Hence, it can be utilised more effectively in aggressive environments. Its global warming potential is lower than mild steel by 74% and stainless steel by 88%. The reduction in carbon emissions is mainly due to the lower energy demands of a single-step extraction from basaltic rock melt.Innovative solutions such as BFRP reinforced concrete that are both environmentally friendly and cost-effective would pave the way for the industry to reduce its energy consumption and carbon emissions. BFRP reinforcement also allows the development of further innovative solutions due to its durability. Its resistance to aggressive environments and lack of corrosion allows for carbon capture concrete technologies that would otherwise lead to corrosion in steel reinforcement. Furthermore, it allows the use of seawater, which reduces the consumption of precious potable water resources.While BFRP rebars are manufactured in the UK and are readily available for construction, UK-based engineering consultancies are unable to specify the product as it is difficult to comply with their professional indemnity insurance policy. It is possible to specify BFRP reinforcement in reinforced concrete when in compliance with the 'design assisted by testing' principle set in the BS EN 1990 UK design standard.BFRP applications that comply with UK standards are limited due to the currently available test data of UK-manufactured BFRP rebars. The proposed testing for this project aims to increase the applications possible with BFRP reinforcement as well as optimise design and improve cost and environmental benefits:-Reliable aggressive environment exposure testing data to BFRP rebar in line with exposure conditions defined in BS EN 206, BS 8500, ISO 10406-1 to determine bar strength retention and optimise the specification of BFRP reinforcement and dowels and environmental performance.-Testing for the determination of BFRP reinforced concrete with and without crack control recycled plastic fibres to facilitate design specification in line with crack width limits set in BS EN 1992\.-Testing of a bespoke BFRP dowel solution to facilitate the specification of BFRP dowels for jointed reinforced concrete construction.

玄武岩纤维增强聚合物（BFRP）加固钢筋混凝土的强度是钢筋的两倍，重量是钢筋的四倍。这意味着钢筋混凝土结构比传统的钢筋混凝土结构需要更少的资源，从而促进钢筋混凝土结构的更安全建造和更有效的物流。与钢不同，它天然耐化学品，不会腐蚀。因此，它可以在恶劣的环境中更有效地使用。它的全球变暖潜能值比低碳钢低74%，比不锈钢低88%。碳排放的减少主要是由于从玄武岩熔体中一步提取的能源需求较低。BFRP加固混凝土等既环保又具有成本效益的创新解决方案将为该行业减少能源消耗和碳排放铺平道路。BFRP增强材料由于其耐用性还允许开发进一步的创新解决方案。它对侵蚀性环境的抵抗力和缺乏腐蚀允许碳捕获混凝土技术，否则会导致钢筋腐蚀。此外，它还允许使用海水，从而减少了宝贵的饮用水资源的消耗。虽然BFRP钢筋在英国制造，并且随时可以用于建筑，但英国的工程顾问公司无法指定该产品，因为难以遵守其专业赔偿保险政策。根据BS EN 1990英国设计标准中规定的“通过测试辅助设计”原则，可以在钢筋混凝土中指定BFRP钢筋。由于英国制造的BFRP钢筋目前可用的测试数据，符合英国标准的BFRP应用受到限制。该项目的拟议测试旨在增加BFRP钢筋的应用，优化设计，提高成本和环境效益：-根据BS EN 206，BS 8500，ISO 10406-1中定义的暴露条件，对BFRP钢筋进行可靠的侵蚀性环境暴露测试数据，以确定钢筋强度保留并优化BFRP钢筋和销钉的规格和环境性能。测试BFRP加固混凝土，有或没有裂缝控制再生塑料纤维，以促进设计规范符合BS EN 1992中规定的裂缝宽度限制。测试定制的BFRP销钉解决方案，以便于规范连接钢筋混凝土结构的BFRP销钉。
