37、re that where the words “as indicated“ are used the sizes, positions or other designated information is actually shown on the design drawings.*The Contractor is responsible for equipment, materials, testing, labor and other items and services required to accomplish the work. Equipment and techniques

38、 proposed for use in the work shall not be used until they have been demonstrated and approved. Materials and equipment, which have not been approved for use in the work, shall not be stored or brought on to Government property. Provide equipment, materials, and labor to demonstrate materials, equip

39、ment, and techniques proposed for use in the work. Perform the demonstrations at the site, at a time and location as directed. The demonstration shall include surface cleaning, excavation, surface patching (including finishing, texturing, and curing materials and methods), curing, safety procedures,

40、 surface finish and appearance. The Contractors quality control shall conform to Section 01 45 01 USACE QUALITY CONTROL. All sampling and testing shall be the Contractors responsibility, and shall be performed by an approved independent commercial testing laboratory, except as otherwise specified.1.

41、3.1 Compressive StrengthEach class or mixture of concrete and mortar proposed for use in the work shall have a 28-day compressive strength matching the compressive strength of the adjacent existing concrete in the structure as determined by SECTION 03 01 30 Page 8Provided by IHSNot for ResaleNo repr

42、oduction or networking permitted without license from IHS-,-,-ASTM C 39/C 39M for concrete and ASTM C 109/C 109M for mortar. Determine the compressive strength of the existing concrete from testing of samples for each portion of the work in accordance with ASTM C 42/C 42M. Take test specimens of exi

43、sting concrete from a sound and intact representative portion of the structure, at locations indicated.1.3.2 Air EntrainmentEach class or mixture of concrete and mortar proposed for use in the work shall have a total air content matching the total air content of the adjacent concrete. Determine air

44、content of the proposed mixture in accordance with ASTM C 231. When air-entrained concrete is required for resistance to freezing and thawing, the concrete shall contain an air-entraining admixture conforming to ASTM C 260 and having an air content as indicated in ACI 301, (Table 3.4.1).1.3.3 Admixt

45、uresConcrete may contain admixtures, such as pigments, water reducers, high-range water reducers, or set retarders to provide special properties to the concrete. Use of admixtures shall be subject to approval.1.3.4 Cementitious ContentEach class or mixture of concrete and mortar proposed for use in the work shall have a cement content matching the cement content of the adjacent existing concrete in order to provide uniform strength, weathering characteristics, and appearance of
