Ways to Recycle and Reuse Concrete

ConstructionAdvantagesBenefitsEquipmentThe early phases of many construction projects involve the demolition of concrete foundations, sidewalks, driveways, and other concrete structures, which can leave a contractor with a sizable volume of heavy, dense materials to deal with. Fortunately, concrete can be recycled and reused in many ways. Typically (but not always) the process involves crushing or pulverizing the concrete rubble near the demolition or buil在thebalancesmb上查看更多信息

Recycled cement ScienceDirect

Cement recycling can reduce the environmental impact caused by the landfills of demolished concrete and the demand of raw materials for producing cement because the waste cement paste in demolished concrete could be used to produce recycled cement.

Recycled Concrete Aggregate an overview

Recycled concrete aggregate (RCA) Recycled concrete aggregate (RCA) comes from demolition of Portland cement concrete. Given that the original concrete might have been strong or weak, dense or open graded, fresh or weathered, then the aggregate’s pieces can be expected to vary similarly.

Recycled Concrete: The Pros and Cons Braen Stone

Recycled Concrete Aggregate At-A-Glance. When a concrete sidewalk, road, parking lot, or structure needs to be excavated and replaced, the concrete is often discarded into a landfill. Because chunks of concrete are not biodegradable and are unable to decompose over time, the waste takes up a great deal of space and creates environmental concerns.
