Water absorption variability of recycled concrete ...

Recycled concrete from building demolition is a heterogeneous material, resulting in a higher standard deviation of many properties of CRCA. One of the important properties of CRCA, needed to design concrete mixes, is water absorption, but the heterogeneous nature of CRCA makes it harder to predict the actual amount of water that will be ...

Effects of Recycled Aggregate on Concrete Mix and Exposure ...

The unit weight of the concrete ranged from 2365 to 2175 kg/m 3, depending on aggregate content (Figure 6).Increasing the recycled aggregate content reduces the unit weight and density of the concrete, resulting in lighter concrete (Figure 6).The unit weights of the 15%, 20%, and 25% mixes were reduced by 8%, 11%, and 11.5%, respectively, compared to plain concrete.

Oct 25, 2017 · 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.
