Life Cycle Assessment of Sustainable Concrete Made With Recycled Aggregates
The results of an environmental study on concrete manufacture that follows the standard protocol of life cycle assessment are shown in this document. The study has been done for seven types of concrete: one conventional and six containing cement kiln dust (10%), marble sludge (10%) and demolition waste (10%, 80% and 100%) respectively, in partial or total substitution of natural aggregate. Six ...
متن کاملCharacterization of Laccase-Treated Kenaf Fibre Reinforced Recycled Polypropylene Composites
Raw and laccase-treated kenaf fibre (KF) were used individually to reinforce recycled polypropylene (RPP) using extrusion and injection moulding. Laccase was used to modify the surface of the fibre to improve the compatibility between fibre and matrix. Enzyme concentration and soaking time were considered as the treatment parameters. Maleic anhydride grafted polypropylene (MAPP) was used with a...
متن کاملLife Cycle Assessment of Completely Recyclable Concrete
Since the construction sector uses 50% of the Earth's raw materials and produces 50% of its waste, the development of more durable and sustainable building materials is crucial. Today, Construction and Demolition Waste (CDW) is mainly used in low level applications, namely as unbound material for foundations, e.g., in road construction. Mineral demolition waste can be recycled as crushed aggreg...
متن کاملLow Cycle Fatigue Behavior of Concrete with Recycled Concrete Aggregates
A comparison of concrete containing recycled concrete coarse aggregates and natural coarse aggregates subjected to high strain, low cycle compressive fatigue is presented. Using a strain based feedback control loop, concrete cylinders are compressed at 15µε/s to a specified strain then unloaded to zero stress for 10 cycles. After cycling, all samples are loaded to a strain of 0.008. Direct conc...
متن کاملConcrete Life Cycle Design
Design and procurement based on holistic whole life appraisal can improve functional quality and, therefore, the overall cost effectiveness and performance of buildings. It is furthermore expected these principles can strengthen the competitiveness of concrete. The initial part of the work, analysed requirements on buildings and how concrete provides answers to these. Life cycle costing, enviro...
