QAQC in Construction

Significance and Use of ASTM C31 Concrete cylinder samples are made for your lab technician to break in a hydraulic press machine and find the compressive strength of the concrete that is being poured for a specific part of a structure. You will get a representative sample of freshly mixed concrete from the truck or mixer, perform slump, temperature, and air content tests on it, and then make cylinders that will be taken back to the lab. These samples provide quality control for architects and engineers and allow them to determine if they will be able to put that concrete into service for their structure, or if they need to remove what they have poured. The cylinders' curing process will help those in charge of the project determine how to best protect the concrete in the structure as it cures and gives them a set of limits for form and shoring removal time. While you are out on site making cylinders, you can keep lookout for errors in the mixing and pouring of the con...

The consultant representative or the quality engineer shall select the area to be tested and shall mark on the drawing. There are many ways to determine the compaction of soil but widely being used  Sand Replacement Method ,  which we are using on our site. And before blinding works, you have to make sure that the inspection request is submitted to the consultant and compaction test report is passed. But first, here are the apparatus and equipment for the In-situ density test. Apparatus for In-Situ Density Test 1. Pouring Cylinder 7. Meter 2. Pointed Steel Rod 8. Hammer 3. Large Screw Driver 9. Bent spoon dibber 4. Sand or Silica Container 10. Gloves 5. Glass plate 11. Metal trays, 500mm square, 50mm depth with 200mm dia. hole in the center 6. Sample container (plastic bag or plastic container) Here are the procedure on how to do the  Compaction test  or  In-Situ Density test . 1. Place the metal tray.  The technician can now...
