CONCRETE SUSTAINABILITY REPORT

From a life cycle perspective, con-crete-frame buildings perform well when compared to steel-frame buildings. As a result, concrete buildings have lower car-bon footprint over their entire life cycle. This paper explores how concrete performs for commercial buildings using life cycle assessment (LCA) methods of determining environmental per-formance. What is Life Cycle Assessment? Life cycle ...

ISO 14041 sets the method by which the embodied energy and product life-cycle environmental impacts should be calculated. In this way, the mix of new and recycled steel and end-of-life recycling are taken into account, taking a "cradle to grave" approach to environmental consideration. So, using UK recycled rates, the figures are 13.1 MJ/kg for steel sections and 12.1 MJ/kg for rebar. The ...

Siliceous slag fertilizer is made with slag, which is stony by-product separated from molten iron during the smelting or refining of ore. The slag is then dehydrated or pulverized into pellet-like shapes to become the final product. The fertilizer contains 25-30% of soluble silicic acid that boosts photosynthesis in rice plants; and 40-48% of alkalinity which improves soil quality.
