BIOprecipitated PHosphates for Improved Low-carbon Innovative Cements (BIOPHILIC)

据估计，普通波特兰水泥生产造成约8%的人为CO2排放。因此，土木工程行业目前是全球变暖的主要贡献者，因为大多数新建筑和现有基础设施的维护都使用水泥。因此，国际上有很多研究工作来生产低碳水泥。本研究的目的是开发新型水泥和灌浆含有磷酸盐生物矿物生产使用微生物的作用，作为一个潜在的更可持续的低碳水泥。将使用可提供磷和/或其他所需基质的废料，其双重优势是同时解决废物管理和低碳水泥生产问题。新型水泥和灌浆将被验证用于使用大量水泥的应用：即封装废物，改善土壤特性（通常在基础设施工程中需要）和混凝土。因此，该项目解决了与基础设施弹性、基础设施脱碳和废物管理（安全废物储存和废物资源化）相关的一系列环境挑战。

Ordinary Portland Cement production is estimated to be responsible for about 8% of anthropogenic CO2 emissions. Thus, the civil engineering industry is currently a major contributor to global warming through the use of cement in most new constructions and maintenance of existing infrastructure. Hence there is a lot of research effort internationally to produce low-carbon cements. This study aims to develop novel cements and grouts containing phosphate biominerals produced using the action of microorganisms, as a potentially more sustainable low-carbon cement. Waste materials which can provide phosphorous and/or other required substrates will be used, with the dual advantage of addressing at a time both waste management and low-carbon cement production. The novel cements and grouts will be validated for applications, which use very high amounts of cement: namely to encapsulate waste, improve soil properties (often required in infrastructure works) and for concrete. The project thus addresses a number of environmental challenges linked to infrastructure resilience, infrastructure decarbonisation and waste management (safe waste storage and waste as a resource).
