Reinforced concrete shall conform to ACI Specification 318-89 or latest revision. <br />C. Field testing and inspection services required will be provided by the Contractor. <br />Cost of such work, except as specifically stated otherwise, will be paid for by the <br />Contractor. Methods of test will comply in detail with the latest applicable ASTM <br />Methods of Testing. <br /> <br />D. Samples of constituents and of concrete as placed will be subjected to laboratory <br />tests. Materials incorporated in the work shall conform to approved samples. <br /> <br />E. Under special circumstances, the Engineer may allow minor deviations from the <br />material requirements specified, provided the resulting concrete quality is not <br />adversely affected or provided a suitable adjustment in cement content is made to <br />compensate for such deviations without cost to the Owner. <br /> <br />SUBMITTALS <br /> <br />A. Submit, as provided in the General Conditions and Section 01340, shop drawings <br />showing placement of forms, form joints, major inserts and blockouts. <br /> <br />QUALITY ASSURANCE <br /> <br />A. The actual acceptance of aggregates and development of mix proportions to <br />produce concrete conforming to the specific requirements shall be determined by <br />means of prior laboratory tests made by the Concrete Supplier or the Contractor at <br />his expense with the constituents to be used on the work. <br /> <br />B. The Concrete Supplier shall submit through the Contractor to the Engineer for <br />approval the concrete mix he intends to use, designed within the limits of these <br />specifications, listing the brand of cement, source and results of tests of <br />aggregates and admixtures not later than 14 days prior to the beginning of placing <br />concrete. <br /> <br />C. The limiting strengths, water-cement ratios and cement factors as shown on (Table <br />A) shall apply. Maximum water-cement (#/#) for structures shall be 0.53 by weight. <br /> <br />TABLE A <br /> <br />Minimum <br />Compo Str. <br />psi at 28 days <br /> <br />Maximum Net <br />Water Content <br />gals/100 Ibs* <br /> <br />Minimum <br />Cement Factor <br />100 Ibs/cu yd** <br /> <br />2500 <br />3000 <br />3500 <br />4000 <br /> <br />7.4 <br />7.0 <br />6.4 <br />5.85 <br /> <br />4.3 <br />4.8 <br />5.64 <br />5.64 <br /> <br />*Maximum; decrease if possible.
