Concrete shall be of such consistency and mix composition that it can <br />be readily worked into the corners and angles of the forms and around <br />the reinforcement, inserts, and wall castings without permitting <br />' <br />materials to segregate or free water to collect on the surface, due <br />consideration being given to the methods of placing and compacting. <br />I. No excessively wet concrete will be permitted, and if at any time <br />concrete of such consistency beyond the limits of Table B is delivered <br />to the job, the Engineer may direct the Contractor to reject same or to <br />add extra cement for which no additional payment will be made. A <br />supply of the approved cement shall be kept available at the site for <br />this purpose. No additional water shall be added by drivers of <br />transit -mix trucks except that established for the design. Failure to <br />comply with this requirement shall be justification for rejecting the <br />' <br />concrete. <br />J.
