1. 1. Optimization of concrete recipe made with crushed aggregate

   University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

   Author : Jonathan Lindekrantz; Pontus Axelsson; [2023]
   Keywords : ;

   Abstract : This paper investigate however concrete recipes with a specific type ofcrushed aggregate can be optimized to reduce cement content for concreteand compares it to concrete made with natural fine aggregate. The different aggregate types are sieved, and the particle size distribution curve is made for each one. READ MORE

3. 2. Accelerated Carbonation Of Cement Pastes And Mortars

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Pejman Hajibabaei; [2022]
   Keywords : karbonatisering; accelerated carbonation; SCMs; cement paste; carbonation depth;

   Abstract : Concrete structures have the largest surface area of all human made structures. Large surface area makes concrete capable to absorb CO2 from environment during its lifetime. It is estimated that concrete during its lifetime can absorb about 15-20% of CO2 which had produced in cement production. READ MORE

   Abstract : The waste framework directive from the European Commission states that 70 percent of allconstruction- and demolition waste (CDW) should be reused or recycled. In Sweden during theyear of 2018, 52,1 percent of the generated CDW was reused or recycled, but a report fromAvfall Sverige showed that reuse only accounted for small fractions of this. READ MORE

6. 5. Dustiness Testing and Particle Characterization of CNT-enhanced Concretes

   University essay from Lunds universitet/Ergonomi och aerosolteknologi

   Author : Sara Marsh; [2021]
   Keywords : concrete; dustiness; airborne particles; carbon nanotubes; Technology and Engineering;

   Abstract : The introduction of fibers into concrete is a common way of reinforcing the mechanical properties and preventing cracking. The fibers act as bridges between the composite components and help reduce the porosity. Today, micrometer-sized fibers are widely used, but there is an increased interest in using smaller fibers e.g. READ MORE
