15、EN 12504-3:2005) has been prepared by Technical Committee CEN/TC 104 “Concrete and related products“, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by Septe
16、mber 2005, and conflicting national standards shall be withdrawn at the latest by September 2005. This European Standard is based on ISO/DIS 8046 “Concrete hardened Determination of pull-out strength“. This standard is one of a series of methods for testing concrete in structures. A draft standard w

For convenience it has now been decided to combine these separate draft standards into three new standards with separate Parts for each method, as follows:
18、Testing fresh concrete (EN 12350) Testing hardened concrete (EN 12390) Testing concrete in structures (EN 12504) This series EN 12504 includes the following Parts where the brackets give the numbers under which particular test methods were submitted to CEN enquiry: EN 12504 Testing concrete in struc

EN 12504-3:2005 (E) 4 Introduction A range of different methods of measuring pull-out force
22、 are available. ISO/DIS 8046 only refers to embedded inserts. This document has been extended to include similar inserts which can be inserted into the hardened concrete and expanded, but which do not create sideways stresses in the concrete. There are methods which rely on gluing or on the producti
23、on of sideways stresses to secure an insert, but it is not yet clear whether these give the same results as the methods included in this part. The measurement can be used to estimate in-situ strength, to determine when post tensioning can proceed, when forms and props can be removed, when winter pro
24、tection and curing can be terminated, or for comparative testing. EN 12504-3:2005 (E) 5 1 Scope This document specifies a method for the determination of the pull-out force of hardened concrete using a cast-in disc insert and rod, or a similar device installed afterwards by drilling into the hardene
