Review of Research on and Implementation of Recycled

The goal of sustainable construction is to reduce the environmental impact of a constructed facility over its lifetime. Concrete is the main material used in construction in the Gulf Cooperation Council (GCC). Therefore, it makes economic and environmental sense to use recycled materials in the making of new concrete for different applications.

Is concrete hazardous waste? Is concrete a hazardous material?

When people ask is concrete hazardous waste, they aren't asking about fresh concrete, they’re usually talking about excess concrete materials. Materials like concrete not used at the jobsite and returned to the plant, fine concrete materials from concrete mixer truck washout, process water from concrete washing and production activities

What to do with "concrete waste" at any type of concrete plant

If it's really waste, bite the bullet and haul it to a landfill (usually at huge costs)! If your material ha sort of value, and you realize it's a potential resource, instruct everyone to stop calling it waste. Maybe you can reuse or recycle the material. Start referring to it as 'concrete material', 'excess concrete material', 'concrete

Proposal of demolished concrete recycling system based on

Waste concrete, the major component of construction waste, can be efficiently recycled and is mainly used as a roadbed or backfill material. However, as no further resource recycling is expected for waste concrete, more efficient and productive recycling systems are sought after. Herein, waste concrete powder is used to produce added-value

Recycling Construction Materials

Table 1 describes how C&D materials are recycled and common markets for those materials. Concrete can be recycled into many markets that currently use crushed stone. Because concrete is commonly recycled, numerous concrete recycling facilities exist across the country. For more information on recycling concrete, visit concreterecycling.org.

Testing of Strength of Recycled Waste Concrete and Its

The compressive strengths of FCM, WCM, and SWCM are compared and the results show that there is not much difference in the strengths of FCM and SWCM after 28 days. For this reason, this study recommends the recycling of waste concrete as an aggregate material in the production of new concrete.

MIT students fortify concrete by adding recycled plastic

Concrete is, after water, the second most widely used material on the planet. The manufacturing of concrete generates about 4.5 percent of the world's human-induced carbon dioxide emissions. Replacing even a small portion of concrete with irradiated plastic could thus help reduce the cement industry's global carbon footprint.
