u.. <br /> 14 <br /> A <br /> E L ° GROUT, NSF <br /> N�AIJSlrGQ <br /> DESCRIP 710H <br /> PUREGOLD GROUT is an easy-mixing, organic-free, high-solids bentonite clay grout engineered <br /> to forma contaminant resistant seal without affecting groundwater chemistry. PUREGOLD <br /> GROUT is a technically superior replacement for traditional cement grouts. PUREGOLD GROUT <br /> .is certified to NSF/ANSI Standard 60, Drinking Water Treatment Chemicals - Health Effects. <br /> RECOMMENDED USE <br /> PUREGOLD GROUT should be used for sealing the annular space in monitoring wells to control <br /> contaminate infiltration and.preserve ambient groundwater quality. <br /> CHARACTERISTICS <br /> • Chemically stable. Results from TCLP Metals Analysis are below RCRA limits for <br /> hazardous constituents <br /> • Contaminant free. All 116 priority pollutants tested for were below TCLP detection limits. <br /> o Generates no heat during mixing or curing and will not damage well casing <br /> • Low permeability, laboratory test results range from 1x10-7 to 1x10.9 cm/sec. <br /> o pH range from 5-5 standard units <br /> a Remains flexible, maintains putty-like consistency over time and will re-hydrate <br /> Thermal Conductivity 0.75 wattstmeterr°C, 0.45 BtulhrlttlF <br /> MIXING AND APPLICATIONS <br /> PUREGOLD GROUT should be mixed with a paddle mixer or a mud rotary recirculation system <br /> and pumped with a positive displacement pump.. it can be mixed in a slurry up to 30% solids. <br /> PUREGOLD GROUT remains placeable for up to two hours and sets in eight hours. <br /> To achieve a 30% solids slurry, add one 50 lb bag of grout to 14 gallons of freshwater. This ratio <br /> will yield approximately 2.2 ft3. <br /> BULIt DENSITY <br /> t 75.55 lbs/ft'when mixed with water to a 30% solids grout. <br /> s <br /> PACKAGING <br /> 50 Ib bag, 48 per pallet.
