This chapter covers commonly encountered concrete work other than concrete paving, which is covered in Chapter 20. Specialized procedures such as pumpcrete, pressure grouting, shotcrete, preplaced aggregate concrete, etc. are not covered. b. Inspectors are cautioned that the contract 'requirements for concrete for a given job are. contained in the drawings and specifications prepared for that job. Also, that contract requirements may change from job to job. There are many dif­ ferences between the requit'ements for concrete for Civil Works construction and concrete. for Military construction, and between the requirements for concrete for large jobs and concrete for small jobsa This guide information will assist you in preparation for the work phase and in the inspection. process together ~ith the knowledgeable application of the spe­ ci.fication requirements for the individual job. 3A-0 2 , RECORDS a. Check ¥11th your su.pervisor and be sure that you know what records you will be required to keep and that you fully understand th·e preparation of the various forms involved. b. Enter the required inforl!lation accurately, completely and promptly in these records. c. In general, the records to be kept -will be prescribed by the Oistrict. Some modifications of the record-keeping system may be in order because of conditions distinctive to a given project I but no such modifications should be made without the full knowledge and approval of your supervisor. 3A-03. MATERIALS a.~ (1) At preparatory inspectlon, before starting conct"ete work check: (a) Has contractor given advance notice of sources of materials? (b) Have samples been furnished? (c) !lave mixes been established? (d) Have tests been coapleted on ai r-entraining a.gent? On curing compound? Concrete placement condi t 1.ons may be such as to re.quire admixture other th8n air-entraining agent or calcium chloride. Has this admixture been tested and approved? Reduction of cement content for basic design mix is not per­ mitted, (e) Have shop drawings for steel reinforcement and embedded items been approved? 3A-l EP 415-1-261 30 Dec 82 (f) Does the aggregate meet the contract requirements? (g) Has cement been tested? (If required) (2) Check as w"Ork proceeds- Are test reports, mill cer­ tificates and other certificates of compliance on hand for all materials being used? (3) Is cement the type specified? b, Storage and Handling (1) Cement (a) Is cement transported from the mill to the mixing plant in weathertight containers? (b) If intermediate storage 1s involved, is cement ade­ quately protected from exposure to moisture during intermediate storage and in loading and unloading operations? (c) Is storage at mlxing plant weathertight and properly ventilated? (d) Is sufficient storage capacity availabl e? (e) Is oldest celQent used first? (f) Has over-age cement, if any been tested? (g) If concrete supplier has other customers, are adequate prec.autions taken to see that cement tested and approved for your job by the Bureau of Standards or the Waterways Experiment Statton is not being used in concrete delivered to others? That untested cement is not being used in concrete delivered to your job? (h) Have arrangements been made to secure all cement from one. manufacturer? ( i) Is the cement being used in the same sequence as 1 t is being delivered? (j) Where pozzolan is used, be sure hin dividers are leak­ proof to assure no contamination of cement. Pennit use of poz­ zolan of only one type and from one source with approved design mtx. Double wall dividers will provide a positive method of avoiding contamination. Do not permit use of pozzolon that is contaminated or damaged. c. Forms (1) General (a) Use specified wood or metal prefabricated or jobsite fabricated units~ (h) Check fitup and bracing to prevent deflection from line and grade. (c) Are forms readily removable, as required? JA-2 EP 415-1-261 30 Dec 82 (2) For concealed surfaces the concrete forms must be tight and sound. {3) For exposed surfaces the forms will be: (a) Made of like-new plywood or equivalent material in 4 by 8 foot sections. (b) Same for form lining. Linings shall have solid backing. (c) Round column foms shall be prefahricated seamless type. (d) Check form panel sizes when joints must be located for architectural alignment. ( 4) Metal forms retained-in-place for slabs; (a) Factory fabricated units are required.
