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

据估计，普通波特兰水泥生产约占人为二氧化碳排放的8%。因此，土木工程行业目前是全球变暖的主要贡献者，因为在大多数新建筑和现有基础设施的维护中使用水泥。因此，国际上有大量的研究努力来生产低碳水泥。本研究旨在开发含有利用微生物作用产生的磷酸盐生物矿物质的新型水泥和灌浆，作为一种潜在的更可持续的低碳水泥。将使用能够提供磷和/或其他所需基质的废物材料，具有同时解决废物管理和低碳水泥生产的双重优势。新型水泥和灌浆将用于使用非常高数量的水泥：即用于包裹废物、改善土壤性质(通常是基础设施工程所需的)和混凝土。因此，该项目解决了与基础设施复原力、基础设施脱碳和废物管理(安全废物储存和废物作为资源)相关的一些环境挑战。

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).
