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

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

    Sammanfattning : 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.

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

    Författare :Dimitrios Boubitsas; Avdelningen för Byggnadsmaterial; []
    Nyckelord :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;

    Sammanfattning : 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.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; cement; limestone filler; chloride ingress; chloride threshold values;

    Sammanfattning : 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. LÄS MER
