  2. 1. Aggregates in Concrete Mix Design

    Author : Yahya Ghasemi; Mats Emborg; Andrzej Cwirzen; Martin Nilsson; Gram Hans-Erik; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mix design; water layer theory; particle packing; aggregates; specific surface area; Byggproduktion; Construction Engineering and Management;

    Abstract : The importance of studying the behaviour and properties of concrete can be highlighted by considering the fact that concrete is the most used man-made material in the world. The very first step in making concrete is its mix design and deciding the type and amount of constitutes used in the production of concrete which should fulfil the requirements of the final product.

  4. 2. Performance based concrete mix-design : aggregate and micro mortar optimization applied on self-compacting concrete containing fly ash

    Author : Sofia Utsi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : This thesis is dealing with the field of self-compacting concrete (SCC). SCC is supposed to fill the form properly and enclose the reinforcement without any external vibration. The fresh properties of such a concrete are thus essential. SCC was first introduced in Japan in the middle of 1980th. READ MORE
