Many depend on circumstances. A major component is cement, which has its own environmental and social impacts and contributes largely to those of concrete. The cement industry is one of the main producers of carbon dioxide, a potent greenhouse gas. [2] Concrete causes damage to the most fertile layer of the earth, the topsoil .As regard to as the environmental and social criteria, the study considers the impact categories listed in Table 1: their values refer to the production of 1 Mg of cement. According to the standard EN 15804 [ 29 ], these categories describe environmental impacts, resource use, and waste categories related to a production.Environmental, Human Health and Socio-Economic Effects of Cement ...Concrete is a critical component in the construction of our modern, industrialized society 1.

The world is changing rapidly, and it’s more important than ever to take steps towards creating a resilient society. Concrete can be an integral part of that resilience by providing shelter in the event of natural disasters. Not only does this manufactured material provide protection against natural forces, but it also offers long-term ...A cradle-to-cradle study on a patented block type made with waste from power plants had less than 50% CO 2 emissions as compared to traditional blocks in the material extraction phase [10].Fly ash and blast furnace slag based alkali-activated binder was employed to make blocks and the LCA results were compared with concrete blocks to observe a maximum reduction of 75% in global warming [11].Ecological impact assessment of sustainable concrete paver blocks based ...How to make sustainability concrete 2.1.
