a � � <br /> 1 <br /> W�0�81�1� Cerlified to <br /> NSFIANSI60 + <br /> ENVI ROPLUG® GROUT is a patented formula bentonite product designed to be used as a water well grouting <br /> fluid, drill hole abandonment fluid, grout for geotechnical monitoring wells after casing placement, and other <br /> geotechnical construction applications requiring non-destructible subgrade seals. Once in place,ENVIROPLUGO <br /> GROUT begins to set and assumes a caulk-like consistency that contacts formations to establish a low <br /> penneability seal(1 X 10"9 cm/sec). <br /> MATERIAL SPECIFICATIONS: <br /> Dry Fineness: 80%min.passing a 200 mesh screen <br /> Processed Bulk Density: 58.0 4:4 pounds/cubic foot <br /> pH: 5%slurry, 8 to 9.8 <br /> Specific Gravity: 10.2 pounds/gallon at 30%solids <br /> Permeability: 1 x 10"9 cm/sec <br /> Thermal Conductivity 0.43 Btu/hr-fVF <br /> ENVIROPLUG® GROUT can be mixed and placed using most available pumping equipment. Although paddle <br /> type mixers and positive displacement pumps work best, mixing can also be done through recirculating systems. <br /> Maximum performance is achieved at a ratio of 1 bag to 14 gallons of water (30% solids). Since pumps such as <br /> double diaphragm or gear pumps may not produce enough pressure to place highly viscous mixtures,the ratio can <br /> be adjusted to I bag per 16 gallons of water and still achieve a good grout"set". <br /> i As ENVIROPLUe GROUT is added to the make-up water, a "pan-cake batter" consistency is generated. <br /> j Pumping at this time is recommended as it minimizes migration into formations and allows for continued <br /> I hydration to take place down hole. <br /> I <br /> Provided local regulations allow, it is always recommended to withdraw the tremic line as grout is being pumped. <br /> This permits the grout to continue its "set" undisturbed, reduces pump pressure and minimizes unnecessary <br /> migration into formations. <br /> Mixing Ratios <br /> Dry Grout Water Usable Slurry Solids Content <br /> 50 lb 14 gal 17 gal 30.0% <br /> 50 lb 15 gal 18 gal 28.6% <br /> 50 lb 16 gal 19 gal 27.3% <br /> TYPICAL E.P.
