Optimization of Compressive Strength of Segmental Interlocking Stones

S Sule

Abstract


The failure of most segmental interlocking stones used as pavement materials is traceable to lack of knowledge of the mix ratios that would optimize the compressive strength of the end products. In this study, the compressive strength was optimized based on Scheffe’s simplex lattice approach. The reliability of model developed was investigated using F-statistic and was found to be adequate. A computer program written in basic language was used to predict with reasonable accuracy, the mix ratios corresponding to a desired compressive strength value that fell within the experimental domain. The mix ratio that optimized the compressive strength was found to be 1:2 (cement: coarse sand), corresponding to a water-cement ratio of 0.526.
