  2. 1. Early age properties of self-compacting concrete - Effects of fine aggregate and limestone filler

    Author : Oskar Esping; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pore pressure; autogenous deformation; self-compacting concrete; plastic shrinkage; BET; specific surface area; rheology; limestone filler;

    Abstract : Self-compacting concrete (SCC) is a sensitive mix, strongly dependent on the composition and the characteristics of its constituents. It has to possess the incompatible properties of high flowability together with high segregation resistance, a balance made possible by the dispersing effect of water-reducing admixture combined with cohesiveness produced by a high concentration of fine particles.

  4. 2. Chloride transport and chloride thresholdvalues-Studies on concretes and mortars with Portland cement and limestone blended cement

    Author : Dimitrios Boubitsas; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; cement; limestone filler; chloride ingress; chloride threshold values;

    Abstract : Reinforced concrete is one of the most widely used building materials and if it is properly designed and produced, it is an extremely durable material with a service life up to 100 years. However, under certain environmental conditions the service life of reinforced concrete structures is more limited. READ MORE

  5. 3. Studies of the efficiency of granulated blast furnace slag and limestone filler in mortars - long term strength and cloride penetration

    Author : Dimitrios Boubitsas; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; k-value; beständighet; durability; kloridinträngning; cement; limestone filler; bruk; långtidsegenskaper; kalksten; chloride diffusion; slagg; chloride migration; compressive strength; granulated blast furnace slag;

    Abstract : This report is the first part of the project Use of industrial by-products and filler in concrete - long term properties/durability. The aim is to improve the knowledge of long term properties/durability of cement and concrete produced using industrial by-products/fillers in order to promote an efficient, safe, reliable and increased use of such types of materials.

    Abstract : Reinforced concrete is one of the most widely used building materials and if it is properly designed and produced, it is an extremely durable material with a service life up to 100 years. However, under certain environmental conditions the service life of reinforced concrete structures is more limited. READ MORE

  7. 5. 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
