Waste Glass in Concrete; Pros and Cons | Concrete Decor

When grinded to a powder, glass becomes one of the natural pozzolans that improves concrete's fresh and hardened properties. While concrete is in its plastic phase, glass powder will increase its workability, so less energy, cost and time are required to place and consolidate the concrete.

Glass recycling - Wikipedia

Glass recycling is the processing of waste glass into usable products. Glass that is crushed and ready to be remelted is called cullet. There are two types of cullet: internal and external. Internal cullet is composed of defective products detected and rejected by a quality control process during the industrial process of glass manufacturing, transition phases of product changes (such as
