This paper studies the current strategies of energy efficiency improvement, CO 2 capture in cement production and fly ash blended cement and concrete. Application of updated technology in newly industrialized countries (especially China) has improved energy efficiency due to their (its) dominant global cement production shares. Waste heat recovery (WHR) increases its energy efficiency. CO 2 capture from cement plants will be more efficient than that from pulverized coal fired power plant. This paper might serve as a guide for the technology improvement, energy policy making and environmental protection in cement production.
