Abstract:
A method of optimizing concrete mix proportioning for a given workability and compressive strength using factorial experimental technique is described. The experiments were designed to consider the simultaneous variations of the controlling factors, namely water-cement ratio, aggregate-cement ratio, and coarse-total aggregate ratio in such a way that the various combinations of these factors would yield mixes in the practical ranges of workability and compressive strength. The aim was also to reduce the number of test mixes and specimens without sacrificing the accuracy of evaluation of the effects of variation of these factors on the workability and compressive strength.
