A RESIN TYPE ADDITIVE USE TO IMPROVE LOAD BEARING CAPACITIES OF GROUTED ROCK BOLTS EXPOSED TO THERMAL CYCLES

نویسندگان

چکیده

A thermoset PMS (Polyvinyl modified silicone) type polymer additive effect on load bearing capacities of cement grouted rock bolt specimens exposed to thermal cycles was investigated with a series experimental studies. The used in this study liquid phase while adding into the fresh mix and started solidify by polymerization after being mixed well grout. silicone based product selected use because its ability contact water. According results study, capacity loss due found be notably limited as result using additive. Therefore, tested assessed improve resistivities bolts against changes.

A NEW CEMENT ADDITIVE TO IMPROVE THE PHYSICAL PROPERTIES OF OIL WELL CEMENT AND TO ENHANCE ZONAL ISOLATION

The main purpose of cementing of the well is to provide effective zonal isolation for the entire life of wells. The standard cements cannot prevent loss of zonal isolation when the stress level in the well cement is severely fluctuated. Since elastic cements improve elastic properties, recently, a number of studies have been done in this area. For this purpose, a nanoparticle, named EX-RIPI, wa...
