ASTM C-42 Concrete Testing <br />1.04 DESCRIPTION <br /> <br />A. Concrete shall be of portland cement, ASTM C-94, fine aggregate, coarse <br />aggregate, water and admixtures as specified and shall be ready-mixed, <br />or transit-mixed concrete. All constituents, including admixture, shall be <br />batched at the central batch plant. <br /> <br />B. Reinforced concrete shall conform to ACI Specification 318-89 or latest <br />revision. <br /> <br />C. Field testing and inspection services required will be provided by the <br />Owner. Cost of such work, except as specifically stated otherwise, will be <br />paid for by the Owner. Methods of test will comply in detail with the latest <br />applicable ASTM Methods of Testing. <br /> <br />D. Samples of constituents and of concrete as placed will be subjected to <br />laboratory tests. Materials incorporated in the work shall conform to <br />approved samples. <br /> <br />E. Under special circumstances, the Engineer may allow minor deviations <br />from the material requirements specified, provided the resulting concrete <br />quality is not adversely affected or provided a suitable adjustment in <br />cement content is made to compensate for such deviations without cost to <br />the Owner. <br /> <br />1.05 SUBMITTALS <br /> <br />A. Submit, as provided in the General Conditions and Section 01340, shop <br />drawings showing placement of forms, form joints, major inserts and <br />blockouts. <br /> <br />1.06 QUALITY ASSURANCE <br /> <br />A.
