B. Water: <br />Potable; containing no impurities, suspended particles, algae or dissolved natural <br />salts in quantities capable of causing: <br />a. Corrosion of steel. <br />b. Volume change increasing shrinkage cracking. <br />C. Efflorescence. <br />d. Excess air entraining. <br />C. Fine Aggregate: <br />1. Washed natural sand. <br />2. Gradation in accordance with ASTM C33 and represented by smooth <br />granulometric curve within required limits. <br />3. Free from injurious amounts of organic impurities as determined by ASTM C40. <br />D. Mix: <br />1. Portland cement, sand and water. Do not use ferrous aggregate or staining <br />ingredients in grout mixes. <br />PART 3 EXECUTION <br />3.1 PLACING GROUT <br />A. Place grout material by pumping quickly and continuously to ensure abandoned <br />dewatering pipe fills to refusal. <br />B. Place vent pipes in dewatering pipes as necessary to assist in filling pipe with grout. <br />C. No grout shall be placed adjacent to any fill section of the embankment prior to the <br />section being constructed to its full height. <br />D. No grout shall be placed prior to Engineer's approval of the embankment construction for <br />the embankment adjacent to the dewatering pipe to be grouted. <br />3.2 FIELD QUALITY CONTROL <br />A. Submit proposed mix design and grouting method to Engineer for review prior to <br />commencement of Work. <br />B. Visually inspect grout as it is delivered to site to determine if adequate slump is <br />maintained to allow for grout to be pumped into abandoned dewatering pipe. <br />END OF SECTION <br />NCCI Pit #1 Reservoir Liner - Technical Specifications Grouting <br />036000 -2 <br />
