He shall also furnish evidence satisfactory to the purchaser that the materials to be used and propor- tions selected will produce concrete of the quality specified. Whatever strengths arc attained the quantity of cement used shall not be less than the minimum specified. 5.5 The proportions arrived at by Options A, B, C for each class of concrete and approved for use in a project shall be assigned a designation' to facilitate identification of each concrete mixture delivered to the project. This is the designation required in 16.1.7 and supplies information on concrete proportions when they are not given separately on each delivery ticket as outlined in 16.2. A certified copy of all proportions as established in Options A, B, or C shall be on file at the batch plant. 5.6 The purchaser shall ensure that the manufacturer is provided copies of all reports of tests performed on concrete samples taken to determine compliance with specification requirements. Reports shall be provided on a timely basis. 6. Tolerances in Slump 6.1 Unless other tOlerances are included in the project specifications, the following shall apply. 6.1.1 When the project specifications for slump are writ- ten as a "maximum" or "not to exceed" requirement: Specified slump: If 3 in. (76 mm) If mom than 3 in. or leas (76 mm) Plus tolerance. 0 0 Minus tolerance: 1 i/~ in. (38 mm) 2"/a in. (63 mm) This option is to be used only if one addition of water is permitted on the job provided such addition does not increase the water-cement ratio above the maximum per- mitted by the specifications. 6.1.2 When the project specifications for slump are not written as a "maximum" or "not to exceed" requirement: Tolemnce~ for Nominal Slumps For Specified Slump off Tolerance 2 in. (51 mm) and less +V~ in. (13 mm) More than 2 through 4 in. (51 to 102 mm) :el in. (25 mm) More than 4 in. (102 mm) :el ~/2 in. (38 mm) 6.2 Concrete shall be available within the permissible range of slump for a period of 30 min starting either on ~arrival at the job site or after the initial slump'adjustment permitted in 11.7, whichever is later. The first and last Ils yd3 or l/n ma discharged arc exempt from this requirement. If the user is unprepared for discharge of the concretes from the vehicle, the producer shall not be responsible for the limita- tion of minimum slump after 30 rain have elapsed starting either on arrival of the vehicle at the prescribed destination or at the requested delivery time, whichever is later. Z,_Ak-_Entrained Con_cretem 7.1 When air-entrai~-'~ concrete is desired the purchaser limits of 11.7 and prior to discharge for placement shows an air content below the specified level by-more than the allowable tolerance in accordance with 7.2, the manufacturer may use additional air entraining admixture to achieve the desired air content level, followed by a minimum of 30 revolutions at mixing speed, so long as the revolution limit of 11.7 is not exceeded (see Note 9). NOTE 9--Acceptance sampling and tearing in accordance with Prac- tice C 172 ia not obviated by this provision. 8. Measuring Materials 8.1 ExcePt as otherwise specifically permitted, cement shall be measured by weight. When mineral admixtures (including ground granulated blast furnace slag, fly ash, silica fume, or other pozzolans) are specified in the concrete proportions, they may be weighed cumulatively with cement, but in a weigh hopper and on a scale which is separate and distinct from those used for other materials. Cement shall be weighed before mineral admixtures. When the quantity of cement exceeds 30 % of the full capadty of the scale, the quantity of the cement shall be within + 1% of the required weight, and the cumulative quantity of cement plus mineral admixtures shall also be within + 1% of the required weight. For smaller batches to a minimum of 1 yda (1 ma), the quantity of the cement and the cumulative quantity of cement plus mineral admixture used shall be not less than the required amount nor more than 4 % in excess. Under special circumstances approved by the purchaser, cement may be measured in bags of standard weight (Note 10). No fraction of a bag of cement shall be used unless weighed. NOT~ l(~---In the United States the standard ~veight of a'bag of portland cenien~ ia 94 lb (42.6 kg) :1:3 %. : 8.2 Aggregate shall be measured by weight.
