The Effect of Zeolite, Silica Fume and Metakaolin on Workability Behavior and Strength of Self-Compacting Concrete (SCC)

Progress in concrete technology has led to the advancement of a new type of concrete, which is known as self-consolidating concrete or self-compacting concrete (SCC). It is a highly flowing concrete that spreads through dense reinforcement, reaches every corner of the formwork, and is consolidated under its own weight without vibration or any other means of compaction. Nowadays SCC is becoming more popular and demandable worldwide due to its workability and efficiency (El Mir et al. 2015 and Khayat. 1999).
Self-compacting concrete (SCC) mixes always contain a powerful superplasticizer and often use a large quantity of filler materials and/or viscosity-modifying admixtures. The superplasticizer is necessary for producing a highly fluid concrete mix, while the filler materials or viscosity agents are required to maintain sufficient stability/cohesion of the mixture, hence reducing bleeding, segregation and settlement (Elyamany et al., 2014).
The present work aims to study the effect of filler types on workability behavior and hardened properties of self-compacting concrete (SCC).
