Hållbarhet för kemankarmassor : Hur kemankarmassor kan väljas utifrån nyckeltal för hållbarhet

Sammanfattning: There are requirements and rules from authorities that companies in the building sector should work towards sustainable development. Sustainable development and sustainable building require knowledge to assess whether the building materials chosen are environmentally, socially, and economically sustainable. In this report, the most essential sustainability indicators for the building material chemical anchor masses have been defined in order to facilitate the sustainability work of companies already at the design and decision stage. Using the methods of literature study, document study and experiments in the form of simulations in calculation software, a selection of chemical anchor masses has been investigated. In order to assess whether a chemical anchor mass is sustainable, a table has been developed in which key sustainability indicators have been defined and then measured. For the definition of sustainability indicators, a document study was carried out in the environmental certification and material databases BASTA, Byggvarubedömningen (BVB), Miljöbyggnad, SundaHus and Svanen. The document study has been carried out with the aim of investigating how the chemical anchor masses are assessed against set sustainability criteria in the databases for the external and internal environment. The cost of chemical anchor masses has been investigated in a literature review. Simulations have been carried out in the calculation programs ESSVE CS, FIXPERIENCE and Hilti PROFIS Engineering to investigate the technical performance of the chemical anchor masses in terms of the load capacity utilization rate of the chemical anchor masses. The defined durability ratios were then measured by comparing the value per harm for the users. Based on the results of the environmental certification and material databases, the cost and the utilization rate of the loading capacity of the chemical anchor masses, a conclusion on how to define and measure a sustainable chemical anchor mass has been developed. The most important key indicators for sustainable chemical anchor masses have been shown in the work to be the impact of the harm that the chemical content of the chemical anchor mass can cause to the internal and external environment, and the harm that the cost of the chemical anchor mass represents to the user. The load capacity utilization rate has proven to be an important key performance indicator as it creates value for the user. When measuring the durability of a chemical anchor mass, the relationship between the harm and the value that the chemical anchor mass represents should be compared. The selection of a sustainable chemical anchor mass should therefore be based on the lowest possible negative impact on the internal and external environment according to the sustainability criteria set out in the environmental and material databases. The dimensional conditions, the load capacity utilization rate, always need to be achieved and this at the lowest possible cost.
