RMu T. <br /> U no E no <br /> NSF/hhrt1�G6 <br /> DESCRIPTION <br /> PUREGOLD GROUT is an easy-mixing, organic-free, high-solids bentonite clay grout engineered <br /> to form a 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 NSFIANSI 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 /> E Generates no heat during mixing or curing and will not damage well casing <br /> A Low permeability, laboratory test results range from 1x10-7 to 1x10-9 cm/sec. <br /> pH range from 5-6 standard units <br /> • Remains flexible, maintains putty-like consistency over time and will re-hydrate <br /> Thermal Conductivity 0.75 watts/meter°C, 0.45 Btu/hr/ft/F <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 /> BULK DENSITY <br /> 75.55 lbs/ft'when mixed with water to a 30% solids grout. <br /> PACKAGING <br /> a <br /> 50 Ib bag, 48 per pallet. All pallets are plastic-wrapped. <br /> t <br /> i <br /> i <br /> E <br /> 2870 Forbs Avenue a Hoffman Estates,IL 60192 a P 800.527.9948 e F 847.851.1332 o wtwr.cetco.comldpg <br /> All weights are approximate.
