Abstract

This research paper reports the Study of influence of fine aggregate particle sizeand fly ash on the workability retention of mortar for Self-Compacting Concrete (SCC). The relative flow area m and the relative funnel speed Rm of mortar were determined using the results of the mortar spread test and V-funnel flow test respectively. The tests were conducted on mortar mixes with five different cement replacement percentage (CRP) by fly ash and four different particle sizes of fine aggregate at an elapsed time of 60 minutes after mixing. The optimum combination of m and Rm were investigated for achieving very good workability retention required for SCC to ensure self-compactability at casting.
