Section 601 Concrete
SECTION 601 ⎯ CONCRETE 601.01 DESCRIPTION. Use concrete consisting of a mixture of cement, fine aggregate, coarse aggregate, and water, with admixtures as specified, combined in the proportions and mixed to the consistency specified, when forming or casting to dimensions specified in the Plans or as the Engineer directs. Provide the materials, material proportions, equipment, and construction methods necessary to ensure that the concrete produced conforms to the Contract. Structural concrete is concrete for structures such as bridges, culverts, and retaining walls. Non-structural concrete is concrete for non- structural items such as sidewalks, entrances, curb and gutter, and roadway median barrier. 601.02 MATERIALS AND EQUIPMENT. 601.02.01 Steel Reinforcement. Conform to Section 811. 601.02.02 Cement. Conform to Section 801. Use Type I cement. The Department will allow the use of Type IA, Type IP, Type IPA, Type IS, Type I(SM), Type II, Type IIA, and Type III when the Engineer approves. The Engineer will condition his approval upon satisfactory means of storage and handling to ensure the ready identification of these cements when used in portions of the work. If unsatisfactory test results are obtained using Types IA, IP, IPA, IS, I(SM), II, IIA, or III cement, complete the work using Type I cement. Do not intermix cement types in any structural unit. 601.02.03 Admixtures. Conform to Section 802. Use air-entraining and water reducing admixtures in all classes of concrete. Water reducing admixtures are not required when slip forming is used for concrete placement. Use other admixtures when the Engineer directs or approves.
