Concrete concept has about 2.5 times lower carbon footprint compared to steel equivalent Concrete concept has about 3 times lower carbon footprint compared to steel equivalent End-of-life: Landfill End-of-life: Recycled Emissions for concrete and steel foundation (tonneCO2/foundation) for base case scenario.
In current study, concrete specimens were printed using a lab-scale printer with the mode of piston extrusion. In contrast, Kruger et al. [50] utilized a progressive cavity pump for concrete transport through the hose to achieve the , resembling the practical at an industry scale. Therefore, different types and scale of ...
Concrete is made from Portland cement, aggregates and water. Its key attributes are compression resistance, durability, fire and impact resistance, insulation properties, porosity and ... (Yang et al. 2015). Some studies highlighted that workability is influenced by the shape of the plastic particle. For example, angular-shaped particle ...
The percentage of plastic waste recycled in 2015 was 16%. Estimations show that in 2021, the recycling rate will increase up to 25%. But if this production estimation turns out to be valid, a significant amount of plastic waste will still be left un recycled (Foti, 2019).Then, there is a necessity of increasing the recycling of plastic waste in the future …
The degree of out-of-plane deformation when the steel case is filled with concrete. Another objective was to evaluate workability—ease of erection of such panels and filling with concrete, as well as the quality of the finished product. In order to study these objectives, a full scale model of height 4 m (1/2 scale) span 8×5 m was built. 5.2.

The LCA methodology is a comprehensive, analytical tool that evaluates the environmental impact of a product or system throughout its entire life cycle (Vieira et al. 2016).Baitz et al. argue that the LCA is a recognized trustworthy tool that conducts scientific and intelligible results to assess the environmental sustainability of human activity. ...
1. Introduction. Concrete is a widely consumed construction material second to water in the world, accounting for nearly 30 billion tons per year due to its low price and ease of preparation [1], [2], although it is a complex and multi-phase material [3].When cement reacts with water, chemical reactions called 'hydration' occur slowly and …
