Abstract:
This diploma thesis gives a comprehensive insight into building with carbon concrete and analyses how the scaling and optimisation potential of carbon concrete can be exploited. The focus is on the extent to which carbon concrete could replace reinforced concrete and what concrete advantages carbon concrete construction has over reinforced concrete construction. The comparison of the economic efficiency shows that carbon concrete can compete with reinforced concrete, especially due to the lower transport, assembly and labour costs. In addition, the comparison of the environmental impact using the example of a bridge made of carbon concrete and its counterpart made of reinforced concrete shows that carbon concrete is significantly more resource and environmentally friendly. In addition, the construction industry was compared with the stationary industry, especially the automotive industry. Based on this, the analysis shows which aspects could be transferred from the automotive industry to the production of carbon concrete components. Firstly, production could be more standardised, as many processes are repetitive. Secondly, the principle of lean construction can streamline the construction and production steps. Thirdly, an adjustment of the prefabrication levels of the carbon concrete components would lead to an acceleration of the construction process on the construction site and fourthly, work structures and conditions need to be improved. Finally, the optimisation of warehousing was investigated, which offers a lot of potential to speed up production processes and thus exploit the scaling potential of new products. Future areas of application exist, but could be expanded by breaking down barriers to market entry.
