2. 1. Recycling of concrete in new structural concrete

   Author : Madumita Sadagopan; Andrzej Cwirzen; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete recycling; sustainability; closed-loop recycling; recycled aggregates; compressive strength; workability mechanical pre-processing; secondary cementitious materials; green concrete; climate-optimized concrete; Resource Recovery; Resursåtervinning;

   Abstract : Concrete waste as crushed concrete aggregates (CCA) in structural concrete gives a new purpose and prolongs the technical life of the reference concrete accomplishing closed loop recycling. This research investigates CCA as aggregate replacement in an industrial reference concrete recipe as fine aggregate fractions and overall aggregate replacement. READ MORE

4. 2. Reducing Radon Gas Emissions in Concrete

   Author : Magnus Döse; Johan Silfwerbrand; Franz Josef Maringer; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radon gas; emissions; health; concrete; building materials; ionizing radiation; Betongbyggnad; Concrete Structures;

   Abstract : Several compulsory regulations and recommendations regarding ionising radiation for building products have been introduced in recent years. Furthermore, industry-affiliated aggregate and concrete companies strive to implement environmental goals that should be fulfilled regarding building materials. READ MORE

5. 3. Sustainability performance of blue-green infrastructure across seasons and with various designs

   Author : Pär Sagrelius; Godecke-Tobias Blecken; Maria Viklander; Erik Glaas; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

   Abstract : The Sustainable Development Goals (SDGs) affect societal development within multiple sectors, both strategically and at street level. For instance, SDG 6 and SDG 11 have contributed to a shift in urban stormwater management that has traditionally been pipe-based, including only control of runoff volumes, to a more multi-functional nature-based blue-green infrastructure (BGI), where"blue" areas are characterized by (temporarily or permanent) open water and "green" areas by vegetative systems.

6. 4. Water and alkali salts in the hydrating and hardened green cement-based materials: Hydration process, moisture content and transport

   Author : Liming Huang; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Formation factor; Electrical conductivity; Moisture transport; Pore structure; Sustainable cement-based materials; Hydration; Alkali salts; Supplementary cementitious materials;

   Abstract : Reducing CO2 emissions in the production of cementitious binder is the most effective way to decrease the environmental impact of the construction industry, so a large amount of supplementary cementitious materials (SCMs) has been used in the green concrete. Both the SCMs and alkali salts in binders influence the hydration process and the structure in hardened cement-based materials. READ MORE

7. 5. Rethinking lawns as prevalent elements of urban green spaces : exploring sustainable lawn alternatives in Chinese mega-cities from social-cultural and ecological perspectives

   Author : Fengping Yang; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Abstract : The lawn is one of the most visible elements of urban green spaces and Western landscape styles. China has seen a dramatic increase in planted lawn areas. READ MORE
