Crushing and using recycled concrete
It has been estimated by the Construction Materials Recycling Association (CMRA), that over 140 million tons of waste concrete are crushed and used each year in the USA. There are signs that increased amounts are being utilized in roadway construction, despite the volume used in various forms; for example, as riprap along eroding shorelines and large-stone fill on building-site access roads. There are further indications that a relatively significant number of road-building agencies are substituting recycled concrete aggregate (RCA) for natural stone in road-base applications, such as that supplied by concrete recycling Sacramento.
Adding to this apparent growing popularity for RCA is the fact of various construction organizations already utilizing RCA and others that are either experimenting or using it as the aggregate in new concrete paving mixes. This indicates the growing awareness of the importance to protect our environment and the natural resources that form part of it, as displayed by concrete recycling Sacramento. With this in mind, it must be considered that the progress in recycling concrete and using it in various construction forms in the USA is lagging behind some regions of the world where natural aggregate and landfill space, are uncommon commodities.
Therefore, committed environment-friendly organizations, such as concrete recycling Sacramento, are an example of how businesses can provide top quality products and services that affect financial savings, whilst at the same time protecting the environment we live in. A prime example of RCA utilization is seen in Austria, where it is a highly valued commodity used as aggregate in new concrete. This product has been used in the manufacture of new pavement concrete as a routine process for reconstructing old concrete pavements in Austria since 1991. Experience has shown RCA to be at least the same standard as high-quality virgin aggregate.
