Multivariate Analysis of the Fresh State Parameters of Self-Consolidating Concrete

Different tests can be performed to measure the fresh state performance of SCC mixes and to ensure that the specified requirements in terms of filling ability, passing ability and segregation resistance are satisfied. The parameters obtained from the slump flow test, V-funnel, L-box and J-ring, dependent on the characteristics of the materials used and their amounts, are also strongly interdependent. This paper studies the structure of correlations among these fresh state parameters and exploits it to develop a general model that relates fresh state performance to mix design characteristics. Experimental results from different papers and reports were collected in a database that was analyzed using data mining and multivariate analysis techniques. The most important aspects of the model developed are described and discussed as a first step towards its further development into a comprehensive tool for a systematic assessment of the fresh state performance of SCC mixes.
