880.2.01 Water for Portland Cement Mixtures
A. Requirements 1. Use water that is reasonably clear without oil, salt, acid, alkali, organic, and other injurious substances. 2. The Department may allow drinking water that is used for ordinary household use without testing it. 3. Do not use water from shallow, muddy, or marshy surfaces. Test and approve all other sources before using them. 4. When the source of water is relatively shallow, ensure that the source depth and intake exclude silt, mud, grass, and all other foreign material. 5. Do not use water with detergents that will entrain air in Portland cement concrete. 6. Do not use water with impurities above the following limits: Impurity Concentration Acidity or alkalinity calculated in terms of calcium carbonate 0.05% Total organic solids 0.05% Total inorganic solids 0.05% Sulfate (SO4) 0.05% Chloride 0.01% B. Fabrication General Provisions 101 through 150. C. Acceptance The Department will reject any water that, when compared with accepted water, shows any indication of unsoundness, marked change in time of set, or reduction of more than 10 percent in mortar strength. Test as follows: Test Method Quality of water, solids ppm AASHTO T 26 Setting time of concrete mixtures ASTM C 403 Mortar making properties AASHTO T 71 Air content of concrete GDT 26 SO4 ppm, Alkalis, ppm ASTM D 516 Cl, ppm AASHTO T 260 D. Materials Warranty General Provisions 101 through 150.
