The RCSPs are made up of expanded polystyrene (EPS) foam core having a spray-on reinforced concrete skins, like a ferrocement overlay, on both sides. The experimental study on RCSPs under blast load was previously conducted by Abbas et al. (2019). The authors investigated the physical damage intensity at different scaled distances by using qualitative fragility curves developed through visual inspection. The study was limited to the specific test plan and there is no quantitative record of the research. Experimental work on RCSPs under blasts requires extensive resources and finances. In order to overcome these limitations, the present study investigates the behavior of RCSPs subjected to blast load by utilizing Abaqus software package. The study aims at developing a numerical simulation through finite element analysis (FEA) which can be extended to other ge...

One of the major causes of these alterations in climate are the greenhouse gases (GHGs) and among them, carbon dioxide is on the lead. In the human sources of CO2 emissions, construction is one of the principal sources, which is a carbon-intensive sector mainly because of the use of concrete and is growing globally at a rapid rate. The main material used for construction purposes is concrete, the third most used substance in the world after air and water. Billions of tons of natural materials are mixed and processed to make concrete, leaving a substantial mark on the environment. Concrete is attractive in resilience and durability because of the special properties of cement. The production of cement is accounted for 5% of the manmade emissions on a global level, releasing 600-700 kg of CO2 per each ton of cement. There is a dire need to make the concrete sustainable.
