This project is a development and demonstration of ARC's low-carbon concrete activator. ARC Marine have been using a non-cement based concrete design for the last two years in the production of their innovative artificial reef units - Reef Cubes. The material is in a state of development and could be offered as an alternative to cement for pre-cast concrete manufacturers and civil engineering projects. ARC's activator offers the potential for massive environmental impact savings compared to cement based concrete. It can be produced with sea water instead of freshwater preventing the use of huge quantities of fresh potable water in concrete production. It also constitutes a massive greenhouse gas emissions saving of 70-100% depending on the specific design of the concrete and the addition of carbon sink additives.In order to develop this material the project aims to develop a number of pre-cast concrete products that will be produced with it. These products will be: a low carbon paving slab, a mass produced nature-inclusive scour protection block & a cubic coastal defence unit. To develop these products the mix will be optimised for several manufacturing methods. By doing so the project will demonstrate the efficacy of the material. Further development work in the project will focus on the material itself both in it's integration to batching plants and in it's documentation to take it a step closer to commercialisation. ARC have received significant interest in the use of the material but the product is not ready for marketing at this time. A key aim of this project will be to take the material to a stage prior of near market-readiness. In doing so ARC will provide a much needed alternative to cement that will help to decarbonise the concrete industry.

该项目是ARC低碳混凝土活化剂的开发和示范。过去两年，ARC Marine 在其创新型人工鱼礁单元——Reef Cubes 的生产中一直采用非水泥基混凝土设计。该材料正处于开发阶段，可以作为预制混凝土制造商和土木工程项目的水泥替代品。与水泥混凝土相比，ARC 的活化剂具有大幅减少环境影响的潜力。它可以用海水代替淡水来生产，从而避免在混凝土生产中使用大量的新鲜饮用水。根据混凝土的具体设计和碳汇添加剂的添加，它还可以节省 70-100% 的大量温室气体排放。为了开发这种材料，该项目的目标是开发一些用它生产的预制混凝土产品。这些产品将是：低碳铺路板、批量生产的自然冲刷防护块和立方体海防单元。为了开发这些产品，将针对多种制造方法对混合物进行优化。通过这样做，该项目将展示该材料的功效。该项目的进一步开发工作将集中于材料本身，包括与配料厂的集成以及其文档，以使其更接近商业化。 ARC 对使用该材料产生了浓厚的兴趣，但该产品目前尚未准备好上市。该项目的一个主要目标是将材料提升到接近上市的阶段。在此过程中，ARC 将提供一种急需的水泥替代品，有助于混凝土行业脱碳。
