production to the requirements of ASTM C 109 The folloving alternates to the testing of grout vill be implemented:
a) Batch Plant Mixed Grout The specifications require that each class of concrete has a companion grout mixture for use on construction joints, buttering pump lines and such other applications as shown on the drawings. As appropriate to the concrete mix, the Erout mix is specified to be the concrete mix *elthout the addition of coarse aggregate,leavin6 the cement, pozzolen. sand (fine aggregate 3/8 inch or less) and admixtures in the same ratio as before and enough veter to provide.the desired consistency. b2t not exceeding the maximum veter/(cement + pozzolan) ratio established for the concrete mix. Since this vill produce a grout at lesst as strong as its companion concrete (due to the high cement content per cubic yard), testing of all the materials used in manufactarin6 Srout is done as part of the concrete in process testing program, and this accomplishes satisfactory quality control of the grout.
b) Premixed Grou't Factory packaged grout which requires addition of vater and 3 mixing in accordance with the manufacturer's instructions vill be tested in accordance with ASTM C 109 for each lot purchased as a quality control check on the factory's production. Since the project specifications require proper storace to prevent deterioration, there is no reason to require daily testing.,
