Paper Title:
Strength Prediction of Fly Ash Concrete Using Cementing Efficiency by Statistical Analysis
  Abstract

This paper offers a model that can estimate the 28-day compressive strength of concrete containing fly ash (FA) using the concept of cementing efficiency. Using various statistical analyses, the prediction model was derived from a wide range of mix proportions and a number of strength test results of concretes used in eight construction sites. A strength prediction model was proposed in terms of a function of the modified cement-water ratio reflecting the equations for cementing efficiency. This prediction model that has R2 of 0.88 and root mean squared error (RMSE) of 1.6MPa is capable of properly predicting the 28-day compressive strength within strength variation of FA concrete.
