EVALUATION OF FACTORS AFFECTING THE TENSILE PROPERTIES OF LIME-TREATED MATERIALS

THE INDIRECT TENSILE TEST WAS USED TO STUDY THE TENSILE PROPERTIES OF LIME-TREATED MATERIALS. ONLY FACTORS INDICATED TO BE IMPORTANT BY A LITERATURE REVIEW (COMPACTIVE EFFORT, COMPACTION TYPE, CURING PROCEDURE, LIME CONTENT, CURING TEMPERATURE, CURING TIME, MOISTURE CONTENT, AND CLAY CONTENT) WERE INCLUDED IN A FRACTIONAL FACTORIAL EXPERIMENT CONSISTING OF THREE EXPERIMENTAL BLOCKS. AN ANALYSIS OF VARIANCE WAS RUN FOR INDIRECT TENSILE STRENGTH TO DETERMINE THOSE FACTORS AND THEIR INTERACTIONS WHICH SIGNIFICANTLY AFFECTED STRENGTH AT PROBABILITY LEVELS OF 0.05 OR LOWER. THOSE EFFECTS AND INTERACTIONS WHICH WERE FELT TO BE SIGNIFICANT IN PRACTICAL APPLICATION OF THE RESULTS ARE PRESENTED IN GRAPHS AND DISCUSSED. IN ADDITION, ALL OF THE DATA FROM THE THREE EXPERIMENTAL BLOCKS WERE POOLED FOR A LARGE REGRESSION WHICH PRODUCED A PREDICTIVE EQUATION FOR INDIRECT TENSILE STRENGTH IN TERMS OF THE SIGNIFICANT FACTORS AND INTERAC- TION. THIS EQUATION CAN BE USED TO ESTIMATE THE TENSILE STRENGTH OF LIME TREATED MATERIALS AND TO AID IN THE DESIGN OF LIME TREATED MIXTURES
