Real Green Concrete ‘’RGC’’ – A Greener and Pervious alternative to OPC

科学上的挑战是设计出既能有效抵御雨水，又环保、经济的材料。传统上，基于普通波特兰水泥（“OPC”）和天然骨料的混凝土已用于透水混凝土的生产。这些材料的问题在于它们对环境的影响；在采石过程中，骨料是众所周知的粉尘来源，而混凝土传统上是由OPC制成的，OPC是向大气中排放二氧化碳的主要贡献者之一（每生产一吨水泥约产生0.6吨二氧化碳）。开发能够控制二氧化碳排放和减少天然骨料使用的新技术，将是水泥行业为减缓气候变化提供解决方案的关键。Una Developments已经开发出了一种技术（真正的绿色混凝土，简称RGC），该技术基于使用各种原材料（如工业副产品，来自工业，包括钢铁制造、发电站和采矿过程）来制造不含OPC的水泥。否则，这些原材料中的大部分将被送往垃圾填埋场。RGC新型配方的高强度、高渗透性和高孔隙度已经在受控的实验室环境中得到了验证。该公司已获得一项专利，另一项正在申请中。该项目的重点是开发一种透水混凝土（由RGC不含OPC的水泥制成），主要用于吸收和/或过滤径流中的水，其输出效率高于传统方法。初步研究表明，RGC是一种理想的候选材料，适用于低渗透率可能导致水淹的应用。该项目将生产一种**环保的** **透水混凝土**（~80%的二氧化碳减少，原材料回收，~30%的用水量减少，基于工业废料作为OPC的替代品），并将为开发环境安全，具有成本效益和耐用性的建筑材料开辟令人兴奋的前景，这些材料具有卓越的工程性能，如强度，孔隙率和耐水性。

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.
