Cost effectiveness with Concrete Recycling
How recycling concrete saves the environment and is cost effective
The recycling of concrete is an established industry in various countries, with the majority of waste concrete able to be crushed and reused as aggregate. The technology exists for concrete recycling Sacramento in the form of mechanical crushing, which makes the operation is readily available and comparatively cost-effective!
The process can be completed in developed and emerging countries, with the potential for further research and development that will increase the applications for recycled aggregate. However, the advances in technology made to date, have achieved significant increases in waste materials recovery. Further increases could be seen dependent on greater public acceptance of recycled aggregate. This must be supported with enlightenment regarding various misconceptions or lack of awareness, related to possibilities for extended usage. Operations such as concrete recycling Sacramento contribute to the reduction in waste landfill dumping and associated site degradation.
Cement contributes approximately 5% to 20% of concrete and is made by crushing and blending clay and limestone, which are materials with a content of oxides, calcium, silicon, aluminum and iron. This material blend is heated to about 1,500°C resulting in the formation of cement hydraulic materials, known as clinker, which irreversibly binds the materials. Following a cooling process, the clinker is ground with small proportions of other additives, such as gypsum added to produce a dry powder; i.e., cement.
The use for which the cement is intended will determine the nature of the ingredients used. They are varied according to the products required and help improve properties; for example, strength, workability, durability, setting time and color. Cement production also uses recycled content from concrete recycling Sacramento, such as fly ash and slag. Waste concrete may be reused as sub-base gravel for the lowest layer of new roads and as gravel for a variety of construction projects.
