Carbonation Depth vs. Physical-Mechanical Properties of Concretes with Alternative Additions of Concrete Recyclate and Silicate Admixtures

摘要

The paper focuses on exploring the correlation dependence between the physical-mechanical properties of concretes - and alternatively concretes with concrete recyclate and silicate admixtures - and the susceptibility of concretes to carbonation. Determining the susceptibility of concretes to carbonation by testing the permeability of their surface layer using the TORRENT, ISAT, or GWT methods is relatively lengthy and requires expensive instrumentation. The first estimate of durability or susceptibility of concretes to carbonation can be easily made on the basis of standard physical-mechanical tests. It seems that the values of volume masses and tensile splitting strengths of concretes could be a good basis for the estimate of their durability.
