Materials shall meet the requirements specified in the following subsections: <br /> 118 <br />' 119 Fine Aggregate 703.01 <br /> 120 Coazse Aggregate 703.02 <br /> 121 Portland Cement 701.01 <br /> 122 Fly Ash 701.02 <br /> 123 Water 712.01 <br /> 124 Air Entraining Admixture 711.02 <br />' 125 Chemical Admixtures 711.03 <br /> 126 Curing Materials 711.01 <br />I 127 Preformed Joint Material 705.01 <br /> 128 Reinforcing Steel 709.01 <br /> 129 Bearing Materials 705.06 <br /> 130 Epoxy 712.10 <br /> 131 Structural Concrete Coating 708.08 <br /> 132 <br /> 133 Type I or II cement shall be used unless high early strength concrete or sulfate resisting concrete <br /> 134 is called for on the plans or as otherwise permitted. Prestressing steel shall meet the requirements <br /> 135 of subsection 714.01 except as noted on the plans. <br /> 136 <br /> 137 Silica fume admixture shall conform to the requirements of subsection 701.03. Calcium chloride <br /> 138 shall not be used in any concrete unless otherwise specified. <br /> 139 <br /> 140 601.04 (unused) <br /> 141 <br />' 142 Construction Requirements <br /> 143 601.05 PrOport/oning. The Contractor shall submit a Concrete Mix Design Report consisting <br /> 144 of design mix proportions, laboratory trial mix and aggregate data for each class of concrete <br /> 145 being placed on the project. Concrete shall not be placed on the project before the Concrete Mix <br /> 146 Design Report has been reviewed and approved by the Engineer. The Concrete Mix Design <br /> 147 cannot be approved when the laboratory trial mix and aggregate data aze the results from tests <br /> 148 performed more than a year in the past. The design mix proportions shall show the weights and <br /> 149 sources of all ingredients including cement, fly ash, aggregates, water, additives and the water <br /> 150 cement ratio (w/c). When determining the w/c, cement (c) shall be the sum of the weight of the <br /> 151 cement, the weight of the fly ash and the weight of silica fume. The laboratory trial mix data <br /> 152 shall include results of the following: <br /> 153 <br /> 154 (1) AASHTO T 119 Slump of Hydraulic Cement Concrete. <br /> 155 <br /> 156 (2) AASHTO T 121 Weight per Cubic Foot, Yield, and Air Content (Gravimetric) of Concrete. <br /> 157 Air content from AASHTO T 152 Air Content of Freshly Mixed Concrete by [he Pressure <br /> 158 Method may be used in lieu of the air content by the gravimetric method in AASHTO T 121. <br />I 159 <br />3-33 <br />G \1011W100 02q\Reportsll(plTachrncai SpaciOcations.tloc FeMuary 3, 2006 <br />
