Mar 22, 2012 Compared to virgin aggregates concrete recyclates have some specific properties because of the attached hardened cement paste. By the method of thermo-mechanical treatment, the hardened cement paste can be removed. In this paper systematic experiments are described. The aim was to understand the liberation process better. The product quality, the parameters of the process concrete grow dramatically with close to 15 million tons used in con-crete, concrete products and grouts in the U.S. in 2005 (ACAA 2006). Historically, fly ash has been used in concrete at levels ranging from 15% to 25% by mass of the cementitious material component.The actual amount used varies widely depending on the application, the properties
