GEOBLOCKS - A novel geopolymer concrete for breakwaters through an industrial symbiosis of waste generated in LCR

**该项目的超乎寻常的目标是开发由回收骨料(RA)和造纸污泥灰(PSA)组成的无水泥土聚合物混凝土的工业应用，并用废硅酸盐**(从CRT和废玻璃中提取)激活**来制造用于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型企业**提出了新的**土聚合物**技术(Geobock)**，将完全取代传统的天然原生骨料和碳密集型传统碱溶液**(这对土聚合物混凝土至关重要)**用三种否则将被送往垃圾填埋场的废流。此外，为了完全取代水泥。**地聚合物水泥是普通波特兰水泥(OPC)的替代品，**是通过组分的碱活化合成的。地聚合物混凝土(GC)非常耐腐蚀性环境，被认为是环保的**(与OPC相比，二氧化碳排放减少了80%**)。然而，用于激活硅酸铝材料的激活剂溶液是使用传统地质聚合物的一个真正令人担忧的领域。激活剂解决方案对土聚合物的二氧化碳含量贡献最大。该项目将使用新型无水泥土聚合物水泥(用废碱硅酸盐激活剂激发)和PSA(具有100%可回收骨料)开发防波堤。**利物浦城区(LCR)是政府新自由港战略的中心，也是全球知名的海洋枢纽，并制定了明确的气候适应战略**。地砖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应用。政府、地方当局和公司已经做出了气候行动承诺，**Geoblock可以通过使用在海水中工作的新的可回收混凝土混合料来帮助和支持减少大气中的二氧化碳*排放**。**基于LCR的Virtus及其子公司将是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，将帮助利益相关者履行他们的碳减排承诺。

**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.
