3. Section-800 4.2 Tests / checks during construction The tests required to be carried out during construction are indicated in Table 800.14 TABLE 800.14: QUALITY CONTROL TESTS DURING CONSTRUCTION S.No. Material / Work Test / Check Frequency 1. Fine and coarse aggregate Moisture content (IS:2386 part 3) Once before commencement of work – each day 2. Cement (consumption) Minimum quantity (Kg/m 3 ) Daily 3. Concrete a) Workability – slump cone test (IS:1199) 2 tests/ day b) Cube Strength (IS:516) Minimum of 6 cubes (3 each to determine 7 days and 28 days strength) to be cast every day) 4. Construction Joints Fixing location before concreting and As and when work demands resumption of work 5. Formwork For stability, leakage of slurry, bulging etc. Throughout concreting 6. Concreting a) Transporting / placing segregation of Random check in each member concrete b) Precautions for hot weather or cold Once check before weather concreting commencement of work c) Compaction with vibrators Regularly 7. Curing of concrete Regular (till 28 days after casting) inspection Daily 4.3 Quality Control Checks by AE / EE Quality checks to be exercised by AE / EE are indicated in Table 800.15 TABLE 800.15: QUALITY CONTROL CHECKS BY AE/EE S.No. Material / Work Test / Check Frequency Designation of Inspecting Officer 1. All concrete components a) Soundness of concrete - Sounding Test by strikingwith a ½ Kg hammer - Schimdt’s Rebound hammer test (if quality is in doubt) After hardening of concrete AE b) Honey Combing and Finishing Before acceptance of work AE c) Tolerances As per drawings AE d) Workmanship As and when inspected EE 2. Cube Strength Review of Cube strength Random EE test results 146
C. Do’s and Don’ts 1. Use cement of the same grade and same source for a single work. 2. Use 20 mm (nominal) size aggregate for RCC. Do’s Don’ts 3. Use potable water with pH value between 6 and 8 for producing concrete. 4. Determine moisture content in both fine and coarse aggregates as frequently as possible to adjust. 5. Remix concrete, if there is segregation after unloading from the mixer. 6. Compact before initial setting of concrete but not later than 30 minutes of its discharge from the mixer. 147 Quality Assurance Handbook for Rural Roads 1. Do not mix different types of cement or mix Blast Furnace Slag with Ordinary Portland Cement at site. 2. Do not use fine aggregates having positive alkali-silica reaction. 3. Do not use sea water for mixing and curing of concrete. 4. Do not increase water content in concrete mix to ‘enhance’ its workability 5. Do not use of aggregates or wooden pieces to provide cover to reinforcements instead of concrete briquettes. 6. Do not drop concrete into place freely from a height exceeding 1.5 m. 7. Do not change or increase the number of construction joints from those shown in drawings. 8. Do not club different lots for the purpose of acceptance.
