Estimation of fresh concrete temperature

Abstract

ACI Committee 305 R proposed an equation for estimating temperature of fresh concrete with ice or without ice. Upon using the equation, it is shown that it is inaccurate. When using ice in percentage greater than 50 % of the mixing water , that equation gives irrational results. Also, ACI Equation under-estimates the actual temperature and it can be used with a little accuracy when using ice as a percentage of added mixing water at 20 % and lower. For more accuracy and rational results and at different percentages of ice to replace mixing water, an experimental test and theoretical analysis have led to a more accurate equation for estimating fresh concrete temperature.
