2. 1. Industrial Application of Sulfur Concrete An Environment-friendly Construction Material

   Author : Amon Raphael Makenya; KTH; []
   Keywords : Sulfur binder; Chempruf modifyer; Sulfur Concrete SC ; Durability; SC market survey; SC Applications; Environment.;

   Abstract : Sulfur Concrete (SC) is a thermoplastic constructionmaterial, of mineral aggregates and modified sulfur as binder.Elemental sulfur has now a low smelting point (120oC) and appears in two solid allotropic forms,separated by considerable contraction. Hence, the need formodification to delay the transition. READ MORE

4. 2. Stimulated autogenous self-healing of mechanically and thermally cracked cementitious materials

   Author : Magdalena Rajczakowska; Andrzej Cwirzen; Karin Habermehl-Cwirzen; Hans Hedlund; Erik Schlangen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggmaterial; Building Materials;

   Abstract : It is estimated that each year, approximately 8 billion cubic meters of concrete are produced worldwide, a vast number comparable to 1 m3 per person, making the construction industry a major contributor to overall global CO2 emissions. Throughout the manufacturing process of the most common cement binder, ordinary Portland cement (OPC), CO2 emissions reach 842 kg per ton of clinker produced. READ MORE

   Abstract : The latest report from the Intergovernmental Panel on Climate Change made once again clear the urge to take immediate actions to reduce the emissions of carbon dioxide and other greenhouse gases. Among the UN Sustainable Development Goals (SDGs), Nr. READ MORE

6. 4. Airborne occupational exposures and risk of developing rheumatoid arthritis

   Author : Anna Ilar; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Background: Rheumatoid Arthritis (RA) is an autoimmune, inflammatory disease with multifaceted aetiology. Cigarette smoke is the strongest environmental risk factor of RA, and research suggests that airborne exposures may trigger RA among genetically susceptible individuals. READ MORE

7. 5. Mechanical activation of clay : a novel route to sustainable cementitious binders

   Abstract : EU Sustainable Development Strategy planned to achieve improvement of life-quality by promoting sustainable production and consumption of raw materials. On November 2018, EU Commission presented a long-term strategy, aiming among others a climate-neutral economy by 2050. Cement production is contributing to 6-10% of the anthropogenic CO2 emissions.
