项目摘要

**The overreaching aim of this project is to develop industrial-scale application of cement-free geopolymer concrete composed of recycled aggregate (RA) and paper sludge ash (PSA) and activated with a waste silicate** (extracted from CRT and waste glass) for manufacturing concrete for breakwaters and other non-structural applications.**Virtus is a Liverpool based SME** proposing novel **geopolymer** technology (Geoblock) **that will completely replace the usage of conventional natural virgin aggregate as well as carbon-intensive conventional alkali solution** (which is essential for geopolymer concrete) with three waste streams that otherwise will go to landfill sites, in addition, to complete replacement of cement.**Geopolymer cement, an alternative to ordinary Portland cement (OPC),** is synthesised through the alkali-activation of constituents. Geopolymer concrete (GC) is very resistant to an aggressive environment and considered eco-friendly **(CO2 emissions cut by 80% compared to OPC**). However, the activator solutions that are used for activating alumina-silicate material represent an area of real concern for the use of conventional geopolymer. The activator solutions provide the highest single contribution to geopolymer's embodied carbon dioxide.This project will develop the breakwater using novel cement-free geopolymer cement activated with waste alkali silicate activator and PSA with 100% recycled aggregates, with validated durability characteristics.**Liverpool City Region (LCR) is at the centre of the new government strategy for Freeports, and a worldwide renowned maritime hub, with a clear strategy for climate resilience in place**. The Geoblock is a new unique design for low carbon used to protect shorelines and coastal areas as well as other non-structural applications. Climate action pledges have been made by governments, local authorities and companies and **Geoblock can help and support the reduction of CO2** **emissions** in the atmosphere by using a new recycled concrete mix that works in seawater.**LCR based Virtus and its subsidiaries will be the first and only company globally to offer such technology**, making us the leading company in the sector with a unique new product that will help stakeholders fulfilling their carbon reduction pledge.

** 本项目的长远目标是开发无水泥地质聚合物混凝土的工业规模应用，该混凝土由再生骨料（RA）和造纸污泥灰（PSA）组成，并用废硅酸盐 **（从CRT和废玻璃中提取）活化，用于制造防波堤和其他非结构应用的混凝土。Virtus是一家总部位于利物浦的中小企业，** 提出了一种新型 ** 地质聚合物 ** 技术（Geoblock）**，该技术将完全取代传统天然原生骨料和碳密集型传统碱溶液 **（这对地质聚合物混凝土至关重要）的使用，并将三种废物流用于垃圾填埋场，此外，还将完全取代水泥。地质聚合物水泥是普通波特兰水泥（OPC）的替代品，** 是通过碱活化成分合成的。地质聚合物混凝土（GC）对恶劣环境具有很强的抵抗力，被认为是生态友好型的 **（与OPC相比，CO2排放量减少了80%**）。然而，用于活化硅酸铝材料的活化剂溶液代表了使用常规地质聚合物的真实的关注领域。活化剂解决方案对地质聚合物的二氧化碳排放贡献最大。该项目将使用新型无水泥地质聚合物水泥开发防波堤，该水泥采用废碱硅酸盐活化剂活化，PSA采用100%再生骨料，具有经过验证的耐久性特性。**利物浦城市地区（LCR）是政府新的自由港战略的中心，也是全球知名的海运枢纽，并制定了明确的气候适应战略 **。Geoblock是一种新的独特的低碳设计，用于保护海岸线和沿海地区以及其他非结构性应用。各国政府、地方当局和公司都做出了气候行动承诺，**Geoblock可以通过使用一种在海水中工作的新型再生混凝土混合物，帮助和支持减少大气中的二氧化碳 * 排放 **。总部位于LCR的Virtus及其子公司将成为全球第一家也是唯一一家提供此类技术的公司 **，使我们成为该领域的领先公司，其独特的新产品将帮助利益相关者履行其碳减排承诺。
