COP26 Installation - 3D Printed Geopolymer Concrete Modular Landscaping Components

混凝土是仅次于水的世界第二大常用材料，也是仅次于化石燃料的第二大二氧化碳排放物。目前，全球建筑业消耗了40%的原材料，产生了全球39%的二氧化碳排放和40%的固体废物，这是一个线性的采用、制造和处置的生产模式。通过使用先进的数字技术、工业共生和循环经济生产模式，我们可以保护我们有限的自然资源，减少排放和废物，并生产出更坚固、更耐用的建筑材料。土聚合物是一种无机聚合物粘结剂，可以通过碱活化具有高铝硅酸盐含量的副产品和废物合成，铝硅酸盐是广泛存在的元素，占地壳的75%以上。这些材料很容易作为各种工业、农业和发电活动的副产品和废物获得。当它与副产品和废弃骨料材料结合在一起时，可以用来生产具有非凡强度、耐久性和耐化学性的快凝混凝土。2021年11月，格拉斯哥将主办其历史上最大的活动-第26届联合国气候变化大会(COP26)。气候谈判将把国家元首、气候专家和活动家聚集在一起，就应对气候变化的协调行动达成一致。我们的项目将展示一种能够实现这些目标的技术，以及实现联合国16个可持续发展目标中的9个目标。它涉及开发一种新型、高性能、低碳的地质聚合物混凝土，利用当地的副产品和废物，在与COP26共同主办的格拉斯哥科学中心，为陆地和漂浮景观设施3D打印模块化混凝土组件。这些组件的灵感来自于连接北爱尔兰巨人堤道和苏格兰芬格尔洞穴的六边形玄武岩柱，这些组件将作为即将到来的中心公共空间美化工程的一部分，用作座椅、花盆和庇护所。它们将作为COP26的标志性背景，展示使用先进的数字技术，如材料表征、无机聚合物合成、参数建模和3D打印来生产高性能、低影响的建筑部件，并作为建筑和基础行业脱碳的典范。

Concrete is the second most commonly used material in the world after water, and second biggest producer of carbon dioxide (CO2) after fossil fuels. The global constuction industry currently consume 40% of all raw materials, producing 39% of global CO2 emissions and 40% of solid waste in a linear take, make and dispose model of production. Through the use of advanced digital technologies, industrial symbiosis and circular economic models of production we can protect our finite natural resources, reduce emissions and waste and produce stronger, more durable construction materials.Geopolymer is an inorganic polymer binder which can be synthesised through the alkali activation of by-product and waste materials with high aluminosilicate content, widely available elements which make-up more than 75% of the earth's crust. These materials are easily sourced as by-products and waste from a wide range of industrial, agricultural and power generation activities. When combined with by-product and waste aggregate materials it can be used to produce rapid-setting concrete with exceptional strength, durability and chemical resistance.In November 2021 Glasgow will host the biggest event in it's history, The 26th United Nations Climate Change Conference (COP26). The climate talks will bring together heads of state, climate experts and campaigners to agree coordinated action to tackle climate change. Action such as the decarbonsiation of our construction and foundation industries - cement, paper, glass, ceramics, metals and chemicals.Our project will demonstrate a technology which can deliver on those objectives in addition to nine of the sixteen UN Sustainable Development Goals. It involves the development of a novel, high-performance, low-carbon geopolymer concrete using local by-product and waste materials to 3D print modular concrete components for land-based and floating landscape installations at the Glasgow Science Centre, co-hosts of COP26\. These components, inspired by the hexagonal basalt columns that link Northern Ireland's Giant's Causeway with Scotland's Fingal's Cave will serve as seating, planters and shelter as part of the upcoming landscaping works to the Centre's public spaces. They will serve as an iconic backdrop to COP26 demonstrating the use of advanced digital technologies such as material characterisation, inorganic polymer synthesis, parametric modelling and 3D printing to produce high-performance, low-impact building components and as a model for the decarbonsiation of the construction and foundation industries.
