PART2 - PRODUCTS <br /> 2.01 MATERIALS <br /> A. Concrete Grout for Soldier Piles <br /> 1. Portland Cement: Coniorm to ASTM C 150. <br /> 2. Mineral Filler: Finely powdered siliceoue matarial which possesses the property <br /> of combining the lime liberated durng the process of hydration of Portland <br /> Cement (approved pouolenic materials conforming to ASTM C 618). � <br /> 3. Fluidifier: Campound with characteristics which will increase the flowability of the <br /> mixture, assist in the dispersal of cement grains, and neutralize the setting <br /> shrinkage of the high-strength cement mortar. <br /> 4. Water: Fresh, clean, free from injurious amount of sewage, oil, acid, alkali, salts, <br /> or organic matter. <br /> 5. Fine Aggregate <br /> a. Sand shall meet requirements cf ASTM C 33, except that the gradatfon shall <br /> be as specified. <br /> b. Sand shall consist of hard, dense, durable, uncoated rocl; particles, and shail ' <br /> be free from injurious amounts of silt, loam, IumpA, soft or flaky particles, � <br /> shale, alkaN, organic matter, mica end other deleterious substances. If � <br /> washed, the washing method shall be such as will not remove desirable fines I <br /> and the sand shall subsequently be permitted to drain until the residual-free i <br /> moisture is reasonable uniform and stable. <br /> c. Sand shall be well-graded from 8ne to coarse, with flneness modulus between <br /> 1.40 and 2.10. When tested, all of the sand shall pass the No. 8 U.S. <br /> standard square mesh sieve. The fineness madulus is defined as the total <br /> divided by 100 oi the cumuletive percentages reteined on U.S. Standerd Sieve <br /> Nos. 18, 30, 50 and 100. <br /> 8. Reinforcing Steel: See Concrete Section 03200, "Concrete Reinforcement." <br /> C. Structural Steel From Rolled Shapea: ASTM A 36. <br /> 2.02 PROPORTIONING <br /> A. Concrete Grout <br /> 1. The concrete grout used to fill the holes shall consist of a mixture of Portland � <br /> Cement, mineral filler, fluidifier, sand, and water. Proportion and mix the concrete <br /> grout to a consistency capable of maintainirg the solids in suspension without ; <br /> appreciable water gain, yet which mey be pumped without difticulty, and which will ; <br /> penetrate laterally and fill voids in foundation material. <br /> April 27, 2001 02458- 3 <br /> . � <br />
