Mathematical Modeling for Prediction of Strength of Remixed Concrete

Abstract

This paper deals with the methodology, related to application  of  mathematical model for reuse of partially set old concrete by adding fresh concrete to form serviceable mix by considering their time lags and  blend ratios.  As Compared to the strength of the freshly prepared concretes the preset concrete obviously gives the reduction in strength. This reduction is further possible to be minimized to a certain extent on blending some quantity of a relatively fresh mix to the existing quantity of the preset mix.
