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 fo r structures such as bridges, culverts, and retaining walls and other items detailed as structures in contract documents. Non-structural concrete is all other concrete.
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 IP( ≤20), Type IS( ≤30), Type IL(5-15), Type II, Type III, and Type V 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 Type IP( ≤20), Type IS( ≤30), Type IL, Type II, or Type III, or Type V cement complete the work using Type I cement. Do not intermix cement types in any structural unit except when finishing with Type I. Discontinue the use of Type V cement used for the purpose of sulfate resistance if unsatisfactory results are obtained. Provide a new mix design addressing sulfate exposure shall be submitted for approval.
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.
601.02.04 Water. Conform to Section 803.
601.02.05 Fine Aggregate. Conform to Section 804.
601.02.06 Coarse Aggregate. Conform to Section 805.
601.02.07 Joint Materials. Conform to Section 807.
601.02.08 Structural Steel. Conform to Section 812.
601.02.09 Miscellaneous Metals. Conform to Section 813.
601.02.10 Concrete Curing Materials. Conform to Section 823.
601.02.11 Masonry Coating. Conform to Section 828.
601.02.12 Mineral Admixtures. Conform to Section 844.
601.02.13 Forms. Provide forms that are mortar tight, true to the dimensions, lines,
and grades of the structure, and of sufficient strength to prevent appreciable deflection during placing concrete.
A.Form Panels. Form panels are continuous sections of form facing material unbroken by joint marks, against which concrete is placed. For exposed surfaces, use form panels of plywood conforming to U.S. Product Standard PS-1 for 601-1
