Abstract [sv]

Detta examensarbete behandlar området stålfiberarmerad betongplatta. Istället för att använda en traditionellt armerad betongplatta undersöks möjligheten att använda sig av den alternativa tekniken stålfiberarmerad betong. Stålfiberarmerad betong består av vanlig betong med iblandning av stålfibrer vilket ger den unika egenskaper.

Rapporten utgörs av en jämförelse mellan en traditionellt armerad betongplatta gentemot en stålfiberarmerad betongplatta. I jämförelsen används ett referensobjekt som är den nya Konsumbutiken i Sunne där traditionell grundläggning med nätarmering använts. Detta alternativ jämförs med en teoretisk framtagen konstruktionslösning där fiberbetong används. Studien behandlar aspekterna dimensionering, genomförande, tid, ekonomi och arbetsmiljö. Målet med studien är att se vilket grundläggningsalternativ som hade varit mest fördelaktigt.

Resultatet som framkommit i denna studie visar att grundläggningsalternativet stålfiberarmerad platta på mark hade varit ett bättre alternativ i det givna fallet. Dimensioneringsmässigt leder den nya lösningen till en slankare konstruktion, enklare genomförande och bättre arbetsmiljö på grund av minskat armeringsarbete. Ekonomiskt blir det stålfiberarmerade alternativet billigare och även tidsbesparande.

Abstract [en]

This report manages the topic of steel fiber reinforced concrete slab. In this study we examine the possibility to use steel fiber reinforced concrete instead of traditional mesh reinforced concrete for the foundation. Steel fiber reinforced concrete consists of ordinary concrete mixed with steel fibers, which give it unique characteristics.

The report is based on a comparison between a traditional mesh reinforced concrete slab and a steel fiber reinforced concrete slab. A reference object has been selected for the study. The reference object is a new supermarket named Konsum in Sunne, Sweden, where traditional mesh reinforced concrete has been used for the foundation. This foundation is compared to a theoretically produced steel fiber reinforced concrete slab. The comparison is based on the following subjects: design, implementation, time, economy and working conditions. The purpose of this report is to determine which alternative is the most advantageous.

The result of this study shows that the steel fiber reinforced concrete alternative would have been a better solution for this foundation. The steel fiber reinforced alternative leads to a slimmer construction, easier implementation and better working conditions due to a smaller amount of reinforcing work. Financially, the steel fiber reinforced alternative is cheaper and leads to a shorter construction time.
