ABSTRACT
This paper presents the results of one part of an investigation with a much larger scope. The aim of this paper is to study the effects of characteristics of different lightweight fly ash aggregates on concrete properties. Regression and graphical analysis of the data obtained for concrete properties were also performed. Analysis of variance (ANOVA) is a useful technique for analyzing the experimental data. Thus, a software TableCurve 3D V4.0 was used for analyzing the hardened concrete properties. The software offers a large number of graphical and numerical tools to enable the user to choose the best equation for particular needs.The validity of predicted values of different models specified by standards and literature, derived in this study and suggested by software was compared and discussed.
