Art. 1001.01 Water
g.Masonry Cement. Masonry cement shall be according to ASTM C 91.
1001.02 Uniformity of Color. Cement contained in single loads or in
shipments of several loads to the same project shall not have visible differences in color.
1001.03 Mixing Brands and Types. Different brands or different types of
cement from the same manufacturing plant, or the same brand or type from different plants shall not be mixed or used alternately in the same item of construction unless approved by the Engineer.
1001.04 Storage. Cement shall be stored and protected against damage, such
as dampness which may cause partial set or hardened lumps. Different brands or different types of cement from the same manufacturing plant, or the same brand or type from different plants shall be kept separate. SECTION 1002. WATER
1002.01 General. Water which has been approved by the Illinois Department
of Public Health for drinking or ordinary household use may be accepted without being tested. All other sources must be approved by the Engineer.
1002.02 Quality. Water used with cement in concrete or mortar and water
used for curing concrete shall be clean, clear, free from sugar, and shall be according to the following.
a.Acidity and alkalinity when tested according to ITP T 26.
1.Acidity -- 0.1 Normal NaOH .................................................... 2 ml max.*
2.Alkalinity -- 0.1 Normal HCI .................................................. 10 ml max.* *To neutralize 200 ml sample.
b.Solids when tested according to the following.
1.Organic (ITP T 26) ................................................................. 0.02% max.
2.Inorganic (ITP T 26) ............................................................... 0.30% max.
3.Sulfate (SO 4) (ASTM D 516-82) ............................................ 0.05% max.
4.Chloride (ASTM D 512) ......................................................... 0.06% max.
c.The following tests shall be performed on the water sample and on deionized water. The same cement and sand shall be used for both tests.
1.Unsoundness (ASTM C 151).
2.Initial and Final Set Time (ASTM C 266).
3.Strength (ASTM C 109). The test results for the water sample shall not deviate from the test results for the deionized water, except as allowed by the precision in the test method. Fine Aggregates Art. 1003.01
1002.03 Water Intake. Water from shallow, muddy, or marshy surfaces shall
not be used. The intake of the pipeline shall be enclosed to exclude silt, mud, grass, and other solid materials; and there shall be a minimum depth of 2 ft (600 mm) of water below the intake at all times. SECTION 1003. FINE AGGREGATES
1003.01 Materials. Fine aggregate materials shall be according to the
following.
a.Description. The natural and manufactured materials used as fine aggregate are defined as follows.
1.Sand. Sand shall be the fine granular material resulting from the natural disintegration of rock. Sand produced from deposits simultaneously with, and by the same operations as, gravel coarse aggregate may contain crushed particles in the quantity resulting normally from the crushing and screening of oversize particles.
2.Silica Sand. Silica sand shall be composed of not less than 99.5 percent silica (Si02).
3.Stone Sand. Stone sand shall be produced by washing, or processing by air separation, the fine material resulting from crushing rock quarried from undisturbed, consolidated deposits, or crushing gravel. The acceptance and use of crushed gravel stone sand shall be according to the Bureau of Materials Policy Memorandum, “Crushed Gravel Producer Self-Testing Program”.
4.Chats. Chats shall be the tailings resulting from the separation of metals from rocks in which they occur.
5.Wet Bottom Boiler Slag. Wet bottom boiler slag shall be the hard, angular by-product of the combustion of coal in wet bottom boilers.
6.Slag Sand. Slag sand shall be the graded product resulting from the screening of air-cooled blast furnace slag. Air-cooled blast furnace slag shall be the nonmetallic product, consisting essentially of silicates and alumino-silicates of lime and other bases, which is developed in a molten condition simultaneously with iron in a blast furnace. The acceptance and use of air-cooled blast furnace slag sand shall be according to the Bureau of Materials Policy Memorandum, “Crushed Slag Producer Certification and Self-Testing Program”.
7.Granulated Slag Sand. Granulated slag sand shall be the graded product resulting from the screening of granulated slag. Granulated slag shall be the nonmetallic product, consisting essentially of silicates and alumino-silicates of lime and other bases, which is developed in a molten condition simultaneously with iron in a blast furnace.
