Egenskaper för betong i ung ålder: Hållfasthets- och värmeutveckling

Abstract [en]

Concrete is a building material used on a large scale in the construction industry. All over the world research are continuously going on to improve the properties of concrete for different purposes. The constituents of the concrete have a major impact on the strength and heat development, which are very important properties for the hardening concrete. The thesis has been carried out through literature studies, laboratory tests, course instruction, and collection of completed test measurements. Based on the obtained measurement results, strength and heat development for totally five concrete mixes are presented. The recipes are prepared by Betongindustri AB in Stockholm. The literature study was conducted by searching both Swedish and foreign literature for hardening concrete with special focus on models for concrete with both Portland cement and the addition of so-called pozzolans (fly ash, slag or silica fume). The information searching is concentrated on the addition of fly ash and is done via the internet, university library and course literature. Information regarding the modeling of fly ash is difficult to find in Swedish literature, but in the English-language literature more information could be found. The main purpose for the laboratory part of the thesis was to investigate the early age concrete and understand how the compressive strength is influenced by varying curing temperature, and determine the heat generated during concrete hardening. To some extent the underlying mechanisms are mentioned, but more fundamental information on existing theories are given by literature references. However, the practical arrangements in the laboratory are presented in the thesis. The experiments were carried out in Complab Laboratory at Luleå University of Technology.
