To investigate the mechanical properties of polypropylene fiber recycled aggregate concrete (PPFRAC) under compression-shear, 69 recycled aggregate concrete (RAC) specimens were tested with the parameters of polypropylene (PP) fiber volume content (0, 0.6, 0.9, and 1.2 kg/m 3), recycled coarse aggregate (RCA) replacement rate (0%, 30%, 50%, …

The average homeowner can create concrete piles when digging up an old driveway or sidewalk. Cement patios in need of repair can also require the need to recycle concrete. What Junk King provides for this type of project are a pair of strong movers who will lift those chunks of concrete and load them onto the back of their truck.

CDW concrete recycling is considered a case of open-loop recycling since the inherent material's properties are changed over the product system and the possibility of endlessly repeated recycling is questionable (not investigated yet). ... they included piles both with natural crushed and recycled aggregates. In their study, Josa et al. 77 used ...

What is the process for disposing of brick and concrete? Got a pile of brick and concrete to get rid of? Renting a roll-off dumpster might be your best bet. It's a speedy, wallet-friendly way to deal with heaps of construction …

The accumulation of discarded PHC pile leads to the waste of substantial land resources. Sua-iam and Makul [6] prepared an environmentally friendly self-compacting concrete using PHC pile waste ...

Now, after five years of weather and use, the recycled concrete has proven that it can perform as well as new concrete and often better. Not only that, but the recycled concrete can be recycled again and used a second and third time without its target strength being compromised, although the rate of strength gain is less with each use.
