Results for tag: "Recycled Concrete Aggregates"

Recycled concrete aggregates (RCA) refer to crushed concrete derived from demolition waste or unwanted concrete structures that is repurposed for new construction uses. Within the cement and concrete industry, RCA presents an opportunity to reduce material costs, conserve virgin aggregate resources, decrease energy consumption, and minimize environmental impact. The blending of RCA into new concrete mixes often involves partial substitution of natural aggregates, potentially altering the fresh and hardened properties of concrete. The process requires careful consideration to maintain the structural integrity of the end product. Research and technological advancements continue to optimize the use of RCA in cement and concrete applications. The market for recycled concrete aggregates is comprised of various enterprises, ranging from demolition contractors and recycling companies to construction materials suppliers and concrete product manufacturers. Some prominent players in this field include Waste Management, Inc., which offers recycling solutions and construction materials, Vulcan Materials Company, recognized for producing construction aggregates and related materials, CEMEX, a multinational building materials company that supplies recycled aggregate, and LafargeHolcim, a leader in building materials that provides innovative concrete solutions incorporating recycled content. These companies, among others, play critical roles in the processing, distribution, and utilization of RCA, driving sustainability in the construction sector. Show Less Read more
