Relation between the Workability and Strength of Self-compacting Concrete

This paper presents the results of an experimental research on the workability and compressive strength of self-compacting concrete. The work focused on concrete mixes having water/binder ratios of 0.35 and 0.45, which contained constant total binder contents of 500 kg/m and 400 kg/m, respectively. The concrete mixes contained four different dosages of a superplasticizer based on carboxylic with and without silica fume. The percentage of silica fume that replaced cement in this research was 10%. The workability tests utilized in this research were the slump flow, V-funnel, L-box, and J-ring, which can be used to evaluate the passing ability of self-compacting concrete. Based upon the experimental results, there are some linear relationships between compressive strength and each of the workability tests executed here.
