Abstract

The self-compacting concretes (SCCs) have undeniable advantages. Since the study on the behavior of SCC containing zeolite and complast sp40 with respect is very rare in literature, the purpose of this study is to focus on this subject. In this study, the influence of the partial substitution of 5%, 10%, 15% and 20% of Pozzalano Portland cement by zeolite and complast sp40 admixtures on the fresh state, compressive strength of self-compacting concrete (SCC) is investigated. For durability, resistance to acid attack, carbonation and marine environment is studied. The results show different behaviors depending on the nature of the pozzolan. In contrast, SCC based on zeolite has a lower resistance compared to the control concrete due to the presence of a large porosity formed during the preparation of the mixture. This study shows and quantifies the positive effect of the partial substitution of Pozzalano Portland cement by 5%, 10%, 15% and 20%. The carbonation study showed a lower resistance of SCCs containing pozzolan, this effect is more important for SCC with zeolite. Additional studies on the formulation and the properties at the fresh state of concrete containing zeolite in order to improve the mechanical strength will surely make it possible to obtain better performance.
