Demolition waste and concrete recycling
Various major cities have experienced surges in the production of construction and demolition waste (CDW) the quantities of which are creating an adverse effect on the environment and the atmosphere. Utilizing this waste material as a recycled aggregate, like concrete recycling in Sacramento can benefit environmental and economic conditions within the construction and associated industries. With this goal in mind, various research and studies have been conducted regarding the possibility of replacing normal coarse aggregate with recycled concrete aggregate (RCA) in concrete used in construction applications.
Demolition waste and concrete recycling. Research has been conducted regarding the potential advantages of recycled materials, such as those used for concrete recycling in Sacramento. The usual and natural aggregates used included sand, dolomite and crushed concretes from different sources. Various tests were conducted to determine compressive and splitting strengths, as well as the degree of material elasticity. From the results obtained, it was seen that concrete rubble when transformed into a recycled aggregate, as with concrete recycling in Sacramento, could be utilized in concrete production, with inherent properties that suited most structural concrete applications.
The demand for construction aggregates worldwide has been estimated at nearly 27 billion tons per year. In many instances, there has been a high increase in the use of natural aggregates, primarily due to infrastructure and construction development. The advantage of concrete recycling in Sacramento among others has shown that recycled aggregate in construction not only contribute to environmental protection but is also economical!
Concrete recycling in Sacramento and similar applications worldwide have the effect of alleviating current methods of managing structural waste by way of landfills, which gas created serious environmental issues. In various developing countries, laws have been introduced to restrict concrete and demolition waste (CDW); for example, forms of prohibition or special taxes for creating waste areas.
