%./ Ile <br /> ENVIROPLUG, GROUT <br /> GerlTied to <br /> NSFIANS!60 <br /> I <br /> ENVIROPLUG® 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 atter casing placement, and other <br /> i 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 /> permeability 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 i 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-ft-°F <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 1 bag per 16 gallons of water and still achieve a good grout"set'. <br /> As EWROPLUG® GROUT is added to the snake-up water, a "pan-calve batter" consistency is generated. <br /> Pumping at this time is recommended as it minimizes migration into formations and allows for continued <br /> hydration to take place down hole. <br /> Provided local regulations allow, it is always recommended to withdraw the tremie line as grout is being pumped. <br /> This permits the grout to continue its "sear undisturbed, reduces pump pressure and minimizes unnecessary <br /> mi ration into formations. <br /> Mixing Ratios <br /> Dr 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 izal 27.3% <br /> TYPICAL E.P.TOXICITY ANALYSIS TYPICAL CHEMICAL ANALYSIS % <br /> SiO2 61.40 MgO 1.70 <br /> Standard to Set Grout m <br /> Arsenic 5,0 <0.10 A1203 18.10 Ca03 0.40 <br /> Barium 100.0 0,50 Fe203 3.50 TiO2 0.20 <br /> Cadmium 1.0 <0.05 <br /> I Chromium 5.0 <0.10 K20 0.10 Na2O 2.30 <br /> Lead 5.0 <0.10 M110 0.10 H2O 4.50 <br /> Mercury 0.2 <0.02 <br /> Selenium 1.0 <0.05 L.O.I. * 4.37 <br /> Silver 5.0 <0.10 'Loss on Ignition <br /> ENVIROPLUe(GROUT is pacicaged in 50 pound Bags. <br /> W-VO-BEN, INC.
