Increased Durability andd Crack Resistance

Recycled plastycs can import surprising mechanical benefits to concrete.

Numerous studies have shown that concrete containg up to 20% plastic aggregate (by volume) can exhibit equal or higher flexural contricth compared to plain concrete, provided the plastic has a rough surface or is chemically treated to improwite bonding.
