Concrete work during the winter - focusing on site casting concrete (English)
Abstract [en]

This report is on concrete work during the winter and is implemented on Peab’s behalf. The assignment was to describe the differences between a summer- and a winter casting. While it shows the complications that exists, it also show what aids are available, both electronic via computer and physical aids.

The information that I have developed is originally from theory in books, information on the internet as well as practical experience from knowledgeable people that works in construction output. Other theories are those I have learned throughout the education to become a construction engineer, including all oral sources over the years.

The results I have come up with, I hope will be able to help future construction projects in the planning phase of a winter casting. While helping the future projects I also would like to just share the results I have come up with, especially the extra costs that rises during a casting in the winter. TorkaS, which was one of the computer programs I used, brought a clear view on the time differences between a summer- and a winter casting which is important to take into consideration during the winter, one of the results is that the summer casting shows a much smoother curve then the winter casting.    

The theory part is the part I focused most on since the whole report is based on facts and not so much numbers in the end. There are several good and useful tips on tools and equipment that facilitate a casting, but also the assembly phase of prefabricated elements. 

Abstract [sv]

Den här rapporten handlar om betongarbeten under vintertid och genomförs för Peabs räkning. Uppdraget var att redovisa de skillnader som finns mellan en sommar- och vintergjutning. En sammanställning visar på de komplikationer som finns, men också vilka hjälpmedel som finnstillgängliga, både elektroniska via dator samt fysiska hjälpmedel. Informationen som tagits fram är ursprungligen från teori i böcker, information från internet samt praktisk erfarenhet från kunnigt folk inom byggproduktion. Annan teori är den som lärts in genom utbildningen till byggnadsingenjör samt muntliga källor under årens lopp. Resultaten jag har kommit fram till hoppas jag skall kunna hjälpa framtida byggprojekt i planeringsfasen vid en vintergjutning. Samtidigt som att hjälpa projekten men också bara dela resultatet som kommit fram genom denna studie, speciellt de extra kostnaderna som uppstår vid en platsgjutning under vintern. Kostnadskalkylen visar på en liten procentuell extrakostnad som uppstår vid en vintergjutning. TorkaS som var ett av de datorprogram som användes utgjorde en stadig del i resultatet där man tydligt kunde se skillnaderna tidsmässigt mellan sommar och vinter, där bland annat en sommargjutning visar på en mycket jämnare uttorkningskurva jämfört med en vintergjutning. Teorin i rapporten väger lite extra tungt då det är den delen mest fokus las på, i den finns ett flertal bra tips på hjälpmedel och utrustningar som underlättar en platsgjutning men samtidigt vid montering av prefabricerade element.
