In the <br /> absence of strength data the cementitious content shall be a maximum 150 lbs/cy. <br /> 4. In-place yield of// at least 98% of design yield for permanent type // a maximum of <br /> 110%of design yield for removable types at I year H. <br /> 2.03 CURING COMPOUNDS <br /> Concrete curing compound shall be a clear compound complying with ASTM C 309,Type I-D, Class A and <br /> B,such as"RES-X"by Burke,or an equivalent approved by CERTIFYING ENGINEER. <br /> PART 3: EXECUTION <br /> 3.01 STRUCTURAL CONCRETE <br /> Place structural concrete as shown on DRAWINGS. <br /> 3.02 INSTALLATION <br /> A.

Vibrators shall be used that <br /> will maintain at least 9,000 cycles per minute when immersed in the concrete. <br /> H. Vibrations shall be used only to minimize honeycomb and accomplish compaction of the concrete, <br /> and shall not be used to move concrete from one location to another. Concrete shall not be moved in <br /> the forms more than 5 feet. <br /> I. The surface of hardened concrete on which fresh concrete is to be placed shall be rough, clean, <br /> sound, and damp.
