Sustainable Design of Basalt Fibre Reinforced Polymer Reinforced Concrete Structures

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，与传统的钢筋混凝土相比，钢筋混凝土结构所需的资源将更少，从而有助于更安全地建造钢筋混凝土结构和更高效的物流。与钢不同的是，它自然耐化学物质，不会腐蚀。因此，它可以在咄咄逼人的环境中更有效地利用。它的全球变暖潜力比软钢低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钢筋混凝土等既环保又经济的创新解决方案将为该行业降低能源消耗和碳排放铺平道路。由于其耐久性，BFRP加固还允许开发更多的创新解决方案。它的耐腐蚀性和无腐蚀性使碳捕获混凝土技术能够在其他情况下导致钢筋锈蚀。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，并可随时进行施工，但英国的工程咨询公司无法指定产品，因为很难遵守他们的专业赔偿保险单。在符合BS EN 1990英国设计标准所规定的‘设计辅助测试’原则的情况下，可以在钢筋混凝土中指定BFRP钢筋。由于目前有英国制造的BFRP钢筋的测试数据，符合英国标准的BFRP应用受到限制。本项目的拟议测试旨在增加BFRP钢筋的应用范围，优化设计并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，以确定钢筋的强度保留，并优化BFRP钢筋和销钉的规格和环境性能。-测试BFRP钢筋混凝土，以确定使用和不使用防裂再生塑料纤维的BFRP钢筋混凝土，以便于设计符合BS EN 1992规定的裂缝宽度限制的规范。-测试定制的BFRP接箍解决方案，以促进BFRP接缝钢筋混凝土结构的BFRP接箍的规范。

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.
