The Effects Of Waste Marble Powder On Sustainable Concrete, Jeremy S. Tennesen
Construction Management
Sustainability has been growing consistently more popular in construction, with projects introducing innovative ideas to build greener every year. One material that has not experienced many innovations since emerging in building use is concrete. The reason behind this could be the chemical process of curing concrete being unique compared to most materials. While concrete can be broken down into some of its original components, water, cement, and admixtures used are not retainable. This makes it difficult to recycle the material, and the aggregates recovered from recycling also experience a loss in strength. With admixtures being involved in most concrete mixes …
