Concrete waste is one of the main types of alkaline waste. Concrete waste usually has a high calcium content, so could form carbonated products through mineral carbonation. The various mineral carbonation methods can be divided into direct and indirect carbonation methods. 7.1. Direct carbonation. Direct carbonation is a simple reaction.

While the cement and concrete industries can help reduce some of our solid waste problems (burning hazardous waste as cement kiln fuel and using fly ash in concrete mixtures, for example), one cannot overlook the fact that concrete is the largest and most visible component of construction and demolition (C&D) waste.

The problem is that even if the insolation contains a small amount of asbestos, it' still incredibly hazardous. Another sub-type of demolition waste is non-asbestos- containing materials like concrete, bricks, tiles, and ceramics.
