The escalating demand on energy consumption as well as the scarcity of non renewable energy resources represents a major concern worldwide. Hence, efforts are being exerted to resort to lower energy alternatives in almost all aspects of life. Portland cement concrete has been known as an energy intensive material that emits large amount of CO2 during its various stages of manufacturing. While concrete has been classified over the decades based on its performance, it has seldom been assessed and evaluated based on its embodied energy. This work aims at evaluating concrete mixtures based on energy and CO2 emission together with strength and durability characteristics. Alternative mixtures were targeted for both normal as well as moderate strength concrete as ones potentially having less energy and less CO2. The results were used to establish a simplified user-friendly model for this process. Results reveal that concrete that is somewhat environmental-friendly can be prepared while fulfilling performance criteria and at a relatively less cost. |
