The scientific challenge is to design materials that are effective in safeguarding against stormwater, whilst being eco-friendly, and cost-effective. Traditionally, concretes based on Ordinary Portland cement (''OPC''), and natural aggregates, have been used in the production of pervious concrete. The problem with such materials is the impact they have on the environment; aggregate is a well-known source of dust during quarrying, and concrete is traditionally made from OPC which is one of the main contributors to CO2 emissions into the atmosphere (approximately 0.6 tonne for each tonne of cement produced). The development of new technology that will lead to the control of CO2 emissions and reduce the use of natural aggregate, will be the key for the cement industry to provide solutions for climate change mitigation.Una Developments has already developed technology (Real Green Concrete, "RGC") based on using a variety of raw materials (such as industrial by-products, sourced from industries, including steel manufacturing, power stations, and mining processes) to make an OPC free cement. The majority of these raw materials would otherwise go to landfills. The high strength, permeability, and porosity of RGC's novel formulation has already been demonstrated in a controlled lab environment. The company has a granted patent and another one pending.This project focuses on the development of a water-permeable concrete (made from RGC OPC free cement) for absorbing and/or filtering water mainly during runoff, at output efficiency levels greater than conventional methods. Initial studies suggest that RGC is an ideal candidate material for applications where low permeability can cause flooding.This project will result in the production of an **eco-friendly** **permeable concrete** (~80% less CO2, recycling of raw materials, ~30% less water required, based on industrial waste as an alternative to OPC) and will open up exciting prospects for the development of environmentally safe, cost-effective, and durable construction materials exhibiting superior engineering properties such as strength, porosity, and water resistance.

科学上的挑战是设计出既能有效抵御雨水，又能环保和具有成本效益的材料。传统上，基于普通波特兰水泥（“OPC”）和天然集料的混凝土已用于生产透水混凝土。这些材料的问题在于它们对环境的影响;骨料是采石过程中众所周知的粉尘来源，而混凝土传统上是由OPC制成的，OPC是向大气中排放CO2的主要贡献者之一（每生产一吨水泥约0.6吨）。新技术的开发将导致控制二氧化碳排放并减少天然骨料的使用，这将是水泥行业为减缓气候变化提供解决方案的关键。（真实的绿色混凝土，“RGC”）基于使用多种原材料（例如工业副产品，来源于工业，包括钢铁制造、发电站和采矿工艺）来制备无OPC水泥。否则，这些原材料中的大多数将进入垃圾填埋场。RGC的新配方的高强度、渗透性和孔隙率已经在受控的实验室环境中得到了证明。该项目的重点是开发一种透水性混凝土（由RGC OPC自由水泥制成），主要用于在径流过程中吸收和/或过滤水，其输出效率高于传统方法。初步研究表明，RGC是低渗透性可能导致洪水的应用的理想候选材料。该项目将导致生产 ** 环保 * 渗透混凝土 **（减少约80%的二氧化碳，回收原材料，减少约30%的水需求，基于工业废物作为OPC的替代品），并将为环境安全的发展开辟令人兴奋的前景，具有成本效益和耐久性的建筑材料，表现出上级的工程性能，如强度、孔隙率和防水性。
