Abstract

Abstract

The cement industry, as a key industry for greenhouse gas emissions, is under enormous pressure to reduce CO₂ emissions. Limestone calcined clay cement developed in recent years is a highly promising low-carbon cement, and its raw materials, clay and limestone has a similar composition to excavated clay and recycled concrete fines in construction and demolition waste. Using the life cycle assessment (LCA) method as a basic framework, this paper evaluated the environmental and economic potential of a composite cement made of the abovementioned construction and demolition waste by creating an inventory analysis of the products. The results showed that the construction and demolition waste composite cement (C³) can reduce CO₂ emissions by more than 24%, compared to the existing cement products, and production costs can be cut down by at least 19%. The future inclusion of the cement industry in the carbon emission trading market will further widen the cost gap between C³ and the existing cement products.
