**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.

**该项目的总体目标是开发由再生骨料（RA）和造纸污泥灰（PSA）组成并用废硅酸盐活化的无水泥地质聚合物混凝土的工业规模应用**（从CRT和废玻璃中提取） ）用于制造防波堤和其他非结构应用的混凝土。**Virtus 是一家位于利物浦的中小企业**，提出新颖的**地质聚合物**技术（Geoblock）**，该技术将完全取代传统天然原始骨料的使用以及碳密集型传统碱溶液*​​（对于地质聚合物混凝土至关重要），另外还含有三种废物流，否则这些废物流将进入垃圾填埋场，以完全替代水泥。**地质聚合物水泥，普通波特兰水泥（OPC）的替代品),** 是通过成分的碱活化合成的。地质聚合物混凝土 (GC) 非常能抵抗恶劣环境，并且被认为是环保的**（与 OPC 相比，二氧化碳排放量减少了 80%**）。然而，用于活化硅酸铝材料的活化剂溶液代表了传统地质聚合物的使用真正令人关注的领域。活化剂解决方案对地质聚合物的二氧化碳含量提供了最高的单一贡献。该项目将使用新型无水泥地质聚合物水泥（用废碱金属硅酸盐活化剂和 100% 再生骨料的 PSA 活化）开发防波堤，并具有经过验证的耐久性特性。**利物浦市地区 (LCR) 是政府新的自由港战略的中心，也是世界知名的海运枢纽，制定了明确的气候适应战略**。 Geoblock 是一种全新的独特低碳设计，用于保护海岸线和沿海地区以及其他非结构性应用。政府、地方当局和公司已做出气候行动承诺，**Geoblock 可以通过使用适用于海水的新型再生混凝土混合物来帮助和支持减少大气中的二氧化碳** **排放**。**LCR 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，使我们成为该行业的领先公司，拥有独特的新产品，帮助利益相关者履行其碳减排承诺。
