摘要

在全球变暖的背景下,需要大幅减少能源和资源消耗,建筑部门也必须采取行动。必须采用节约资源的建筑方法,同时使基础设施和住房等领域不断增加的建筑任务得以继续完成。为了成功地将一种新的建筑方法引入市场,除了政府对气候中和和技术性能的重要要求外,可回收性和经济效率方面也是必不可少的。最重要的是,经济可行性,即经济上的优势,以及它与竞争系统相比的简单适用性,决定了一项新技术的成功和广泛使用。碳增强混凝土以其优异的技术性能和同时的材料效率,是建筑行业实现气候中和的重要组成部分。这是一项很有前途的技术,但仍需证明其经济优势和在市场条件下的强大适用性。除了基础设施领域,在住房建设领域也有巨大的潜力,需要开发碳增强混凝土。为了应对这一挑战,有必要设计一个有竞争力的价值链,允许在现有工厂技术上批量生产适销对路的产品。本文以c3结果建筑CUBE为例,简要概述了碳混凝土预制建筑领域的经济和生态现状。特别是,由预制和半预制部件制成的CUBE-BOX,更详细地进行了检查,并将所使用的碳增强混凝土部件与经典的钢筋混凝土结构在可持续性方面进行了比较。在此背景下,基于潜在的细分市场,预测了碳增强混凝土施工方法对全球气候保护的贡献。

The ecological and economic advantages of carbon reinforced concrete—Using the C3 result house CUBE especially the BOX value chain as an example

The ecological and economic advantages of carbon reinforced concrete—Using the C3 result house CUBE especially the BOX value chain as an example

Against the background of global warming and the associated need to drastically reduce energy and resource consumption, action must also be taken in the building sector. Resource-efficient construction methods must be used that nevertheless allow the increasing construction tasks in areas such as infrastructure and housing to continue to be fulfilled. In order to successfully introduce a new construction method to the market, the aspects of recyclability and economic efficiency are essential, in addition to important government requirements for climate neutrality and technical performance. Above all, the economic viability, that is, the economic advantageousness, as well as its simple applicability compared to competing systems, decides on the success and widespread use of a new technology. Carbon reinforced concrete, with its outstanding technical properties and simultaneous material efficiency, is an important building block toward climate neutrality in the construction industry. It is a promising technology that still has to prove its economic advantages and robust applicability under market conditions. In addition to the infrastructure sector, there is great potential in the area of housing creation, which needs to be tapped for carbon reinforced concrete. For this challenge, it is necessary to design a competitive value chain that allows the realization of marketable products in mass production on existing plant technology. The article gives a short overview of the economic and ecological status quo in the field of prefabricated construction with carbon concrete, using the example of the C3-result building CUBE. In particular, the CUBE-BOX, which is made of prefabricated and semi-prefabricated parts, is examined in more detail and the carbon reinforced concrete components used are compared with classic reinforced concrete constructions in terms of sustainability. In this context, the conceivable global climate protection contribution of the carbon reinforced concrete construction method is forecast based on potential market segments.
