quality control in concrete construction work,quality control after construction; stage-1 (quality control before concreting) this stage of quality control consists of two steps. checking of specification requirements regarding excavation, forms, reinforcement and embedded fixtures etc. control test on concrete ingredients (i.e. on cement, aggregate & water) cement. quality of cement is.inspector’s manual for hma/pcc construction,the purpose of this manual is to provide guidance to the inspector, quality assurance (qa), and quality control (qc) representatives on construction oversight of hot mix asphalt (hma) and portland cement concrete (pcc) airfield pavements. this manual is not a contract document and does not take the place.

construction inspector’s checklist for portland cement concrete pavement . while its use is not required, his checklist has been prepared to provide the field inspector a t summary of easy-to-read step-by-step requirements relative to the proper construction of pcc pavement (section 420). the following questions are based on information found in
quality control for concreting in construction: 0. concrete is a heterogeneous mixture of cement, coarse aggregate, fine aggregate (sand) and water. in addition to the above concrete needs the use of special materials which is admixture to reduce the water-cement ratio of mix. mineral or chemical admixtures are generally used for construction
you can also check aci 311 'guide for concrete plant inspection and testing of ready-mixed concrete' and aci 363 'guide to quality control and testing of high-strength concrete'. be warned, your inspectors may get flack from the plant if they try and do more than read the tickets.

this concrete quality control checklist is free to use and easily editable, shareable and printable for your own company and projects. concrete is the most widely used construction material - used on every kind of project and in batches of all sizes.
concrete depends on type of concrete, i.e. pcc or rcc, type of elements to be casted, such as rcc slab, columns, footing, beams, walls etc. although it is easy to remember number of checks during inspection of concrete member, a checklist is always required for record of the placement of concrete and quality control measures taken at site.
