Common use of MATERIAL REQUIREMENTS Clause in Contracts

MATERIAL REQUIREMENTS. Use a Department approved pre-packaged, non-shrink, non-metallic grout. Contact the Materials and Tests Unit for a list of approved pre-packaged grouts and consult the manufacturer to determine if the pre-packaged grout selected is suitable for the required application. When using an approved pre-packaged grout, a grout mix design submittal is not required. The grout shall be free of soluble chlorides and contain less than one percent soluble sulfate. Supply water in compliance with Article 1024-4 of the Standard Specifications. Aggregate may be added to the mix only where recommended or permitted by the manufacturer and Engineer. The quantity and gradation of the aggregate shall be in accordance with the manufacturer’s recommendations. Admixtures, if approved by the Department, shall be used in accordance with the manufacturer’s recommendations. The manufacture date shall be clearly stamped on each container. Admixtures with an expired shelf life shall not be used. The Engineer reserves the right to reject material based on unsatisfactory performance. Initial setting time shall not be less than 10 minutes when tested in accordance with ASTM C266. Test the expansion and shrinkage of the grout in accordance with ASTM C1090. The grout shall expand no more than 0.2% and shall exhibit no shrinkage. Furnish a Type 4 material certification showing results of tests conducted to determine the properties listed in the Standard Specifications and to assure the material is non-shrink. Unless required elsewhere in the contract the compressive strength at 3 days shall be at least 5000 psi. Compressive strength in the laboratory shall be determined in accordance with ASTM C109 except the test mix shall contain only water and the dry manufactured material. Compressive strength in the field will be determined by molding and testing 4” x 8” cylinders in accordance with AASHTO T22. Construction loading and traffic loading shall not be allowed until the 3 day compressive strength is achieved. When tested in accordance with ASTM C666, Procedure A, the durability factor of the grout shall not be less than 80.
