Utjecaj sastava mješavine samozbijajućeg betona na robusnost

Abstract

An experimental program aimed at evaluating robustness of four distinct types of self-compacted concrete (SCC) is presented in this paper. A control mix was designed and three series of mixes were made, with variation of principal fresh mix properties. In order to evaluate robustness, the selected mixes were subjected to variations in water content. The tested mixes were then ranked using the multi-attribute decision making method. The results indicate that the reduction in segregation resistance, and the decrease in the obstacle passing ability, lead to a considerable decrease in robustness of self-compacting concrete.
