STATISTICAL ALLOCATION OF SOIL SPECIMENS TO ELIMINATE INACCURACIES IN DIFFERENTIAL MOLDING TIME

COMPRESSION TESTS OF STABILIZED SOILS CAN BE INFLUENCED BY MOLDING TIME DIFFERENCES WHEN SEVERAL SPECIMENS ARE MOLDED FROM ONE BATCH. IF THE TIME LAG HAS A LINEAR INFLUENCE ON THE STRENGTH OF THE SPECIMENS, COMPARISONS AMONG TEST CONDITIONS ARE FREE OF INACCURACIES, DUE TO MOLDING TIME DIFFERENCES, WHEN THE AVERAGE MOLDING SERIAL NUMBER IS THE SAME FOR EACH TEST CONDITION. IT IS ALWAYS POSSIBLE TO APPLY THIS RULE TO ANY EXPERIMENTATION. A PILOT EXPERIMENT WITH SOIL-CEMENT MIXTURES SHOWED THAT A RANDOM SELECTION OF SPECIMENS CAN YIELD INACCURATE RESULTS, WHEREAS THE USE OF THE SYSTEMATIC MOLDING-TIME ALLOCATION IS CONDUCIVE TO ACCURATE RESULTS. /NAPA/
