Title: Rationlization of the Trial Mix Approach to Concrete Mix Proportioning and Concrete

Abstract:An integral part of concrete mix proportioning is the pre-paration of trial mixes. The success of and adjustments to such trials are largely a matter of judgment which has not been analyzed quantitatively in the existing methods. This paper reviews such proportioning methods and presents the data in a form whereby any desired end result can be extrapolated after one trial mix (successful or not). The method uses the factors of fineness modulus (of both aggregates and total mix) and water content (as percentage of the total ingredients) as the factors influencing the end result. Charts and formulas are presented which show the manner in which these variables may be influenced.
