2. 1. Sensing capability of nanomodified Portland cement composites

   Author : Thanyarat Buasiri; Andrzej Cwirzen; Karin Habermehl-Cwirzen; Jan Olek; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensing cementitious composites; nanomodified Portland cement; Carbon nanofibers; CNF; piezoresistive materials; sensor; cement-based sensor; self-monitoring; sensing capability; Byggmaterial; Building Materials;

   Abstract : Sensing cement-based composites refer to composites that have sensing functionality that can measure several physical and chemical parameters. Sensing cement-based composites are fabricated by incorporating some functional fillers, such as conductive fibers (CFs), carbon nanofibers (CNFs), carbon nanotubes (CNTs), and graphene, into conventional concrete.

4. 2. Shrinkage and Related Properties of Alkali-Activated Binders Based on High MgO Blast Furnace Slag

   Author : Abeer Humad; Andrzej Cwirzen; John L. Provis; Karin Habermehl-Cwirzen; Andrzej Garbacz; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alkali-activated slag; alkali-activated materials; high-MgO blast furnace slag; shrinkage; creep; carbonation; strength; heat curing; Byggmaterial; Building Materials;

   Abstract : Concrete is the second most used material in the world just after water. A drawback is that it is mostly based on Portland cement, which has an extremely high carbon footprint reaching a staggering 900 kg/tonne. The carbon dioxide emissions related to the production of the Portland cement accounts for nearly 8 % of the global total. READ MORE

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fukttransport; materialegenskaper; permeabilitet; teori; beräkningsmetoder; mätmetoder; byggmaterial; forskningsresultat;

   Abstract : The purpose of this licentiate study is to analyze capillarity transport in building materials, and in order to do that, develop a new measurement method by which the moisture diffusivity at high moisture levels can be measured in an easy way.... READ MORE

6. 4. Low Portland cement content concretes at freezing and subfreezing temperatures

   Author : Ankit Kothari; Andrzej Cwirzen; Hans Hedlund; Karin Habermehl-Cwirzen; Aleksandra Radlinska; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggmaterial; Building Materials;

   Abstract : Concrete is the most used building material. With the increasing growth of industries and urbanization globally; the demand for concrete is increasing significantly. Ordinary Portland Cement (PC) is the binder used to produce typical concrete. Unfortunately, for every ton of manufactured cement about 0. READ MORE
