EXPERIMENTAL STUDY ON WORKABILITY AND MECHANICAL PROPERTIES OF PISOLITE GROUTING MATERIAL

The effects of different amount of water and pisolite on the workability and mechanical properties of pisolite grouting material(PGM) were studied.The results showed that the workability of PGM with 13% water content was better,the mechanics indexeal of PGM decreased with the increment of water,and increased with the enhancement of pisolite when the amount of water less than 14% and pisolite less than 35%,moreover,tensile strength of PGM was approximately 40% higher than that of ordinary concrete.Finally,based on the experimental data,the regression formulas among mechanical indexes were put forward.
